Key Points:
When traveling overseas, you should:
-
Consider visiting a travel clinic prior to departure. Travel clinics can provide
specialized immunizations and prescriptions for medications, as well
as providing essential advice about how to prevent or treat illness
abroad.
-
Learn about the availability and quality of health care available at
your destination.
-
Know how to obtain the names of qualified, English-speaking doctors
and which facilities provide the best care at their destination.
-
Purchase a travel health policy that directly pays doctors and
hospitals abroad and that also coordinates and pays for emergency
medical evacuation.
-
Carry standby antibiotics to treat travelers’ diarrhea, and bring at
least a basic first aid kit.
-
Have available copies of key portions of your medical records
(e.g., a recent ECG) and a list of their medications, if health
problems are a concern.
-
See a physician immediately if a fever develops during a trip to the
tropics or soon after your return. Malaria is a medical emergency
you may need to consider.
What's New?
-
Travelers should consider carrying the
nonabsorbable antibiotic rifaximin (Xifaxan) to treat travelers'
diarrhea (TD). It is effective against E. coli, the most common
cause of TD.
-
Prophylactic treatment with rifaximin
600 mg/d for 14 days safely and effectively reduced the risk of
developing travelers' diarrhea in US travelers to Mexico.
Rifaximin is effective against enterotoxigenic E. coli (ETEC) and
enteroaggressive E. coli (EAEC) and has also shown effectiveness in
the prevention
of shigellosis.
-
The non-DEET repellent picaridin is
now available in a 20% formulation and is comparable to DEET for
protecting against mosquito bites that transmit malaria and other
infectious tropical diseases. It has more favorable cosmetic
properties than DEET and will not damage synthetic materials, such
as plastic.
-
Traveler-ER is a USB device
(flash drive) that
securely stores copies of your medical records and does not rely on
a central data base.
-
Starting in May 2009, Portable Oxygen
Concentrators must be allowed on all flights originating or ending
in the United States. This will require all airlines operating in
the US, including foreign airlines, to allow the use of approved
POCs on-board and in-flight.
When preparing for your trip, list the countries you will be visiting
(in order) and the length of time you plan to spend in each one. There
are four questions you need to answer about your trip, which will
determine the degree of detail needed in planning ahead.
What is My Destination?
You should ask yourself the following questions: What illnesses are
prevalent in the region I will be visiting? What is the general level of
sanitation? How competent, and close by, is medical care? How harsh is
the climate? How safe are the roads? Is the country politically stable?
Also, remember that a trip to Western Europe, for example, doesn’t
require as much preparation as an extended stay in a remote village in a
less developed region. Because some countries and cities are much safer
than others, be careful not to overdo precautions. You don’t need a
typhoid shot if you are going to London or Tokyo, nor do you necessarily
need a whole series of immunizations if you’re taking a brief trip to a
less developed country but staying exclusively in a deluxe hotel in a
large city. For updated information on country-by-country disease risks,
consult the World Medical Guide section of this book.
What Will I Be Doing?
Staying in rural areas of less developed countries puts you at greater
risk of contact with unsanitary food and drink and usually brings
greater exposure to disease-carrying insects. (However, some diseases,
such as dengue fever, are also transmitted in urban areas. There is also
the risk of malaria in most cities in sub-Saharan Africa.)
Traveling on a tour and staying only in air-conditioned, deluxe hotels,
typically carries less risk than traveling in rural areas off the usual
tourist routes. Planning an adventure or wilderness itinerary with
exposure to extremes of heat, cold, or altitude also takes additional
preparation, as does trekking or camping in a remote area far from
medical care. Driving a car, motorcycle, or moped in a less developed
country may be quite hazardous as motor vehicle accidents account for
most preventable fatalities among travelers. Higher risk activities also
include swimming in unfamiliar, possibly treacherous, waters, or
wading/rafting in freshwater ponds, lakes, or streams. Engaging in
casual, unprotected sex is another potential health problem. Therefore,
a close analysis of your activities is critical in helping you avoid
illness and injury.
How Long Will I Be There?
A brief trip usually means less exposure to diseases and less
opportunity for an accident. Longer trips increase the likelihoods of
side trips and excursions that may place you at an unforeseen risk,
perhaps for a mosquito-transmitted disease such as malaria. Longer
travel may also cause you to discontinue prophylactic antimalarial
medication, abandon safe food and drink practices, or neglect insect
protection measures. Long-stay travel also brings with it the risk of
“culture shock” and the need to know more about local customs,
traditions, and history. Therefore, if you will be working overseas, you
must also consider what psychological stresses you, and perhaps your
family, will experience while adjusting to life abroad and what
resources you will need beforehand to help make a smooth adjustment.
What Should I Bring?
Your itinerary, the climatic conditions you expect to encounter, the
duration of your trip, and the disease risks in the countries you will
be visiting all influence what you should bring. For example, many
travelers to tropical and subtropical regions neglect to take
precautions against insect bites necessary to prevent malaria and other
insect-transmitted diseases. Be sure you have the necessary supplies
(DEET repellents,
permethrin insecticide,
mosquito netting) described in
Chapter 8. Your health status may also require you to take additional
precautions.
When traveling overseas, take an ample supply of any medication that you
use regularly, as well as copies of your prescriptions and the generic
names of the medications; brand names are usually different overseas. Do
not carry a mixture of pills in unmarked vials. To avoid problems with
customs officers who might suspect that your pills are recreational
drugs or illegal narcotics, keep each medication in its labeled original
container. Note: Certain
countries deny entry to HIV-positive travelers. If you are HIV-positive,
be prudent when packing your medications.
Carry legally prescribed narcotics and controlled drugs (tranquilizers,
sleeping pills, etc.) only if medically necessary. If you are a diabetic
taking insulin and carrying needles and syringes, you may also arouse
suspicion at customs checkpoints. Obtain a letter on a professional
letterhead from your doctor certifying the need for these medications
and certifying your diagnosis and treatment. The same applies if you
will be carrying needles and syringes in an HIV/hepatitis prevention
kit.
Use the following checklists as general guidelines and modify them
according to your itinerary and specific travel and health needs. A
nylon or canvas pack (e.g., the
Wallaby Trip Kit by Eagle Creek) or a
first aid kit are
useful for carrying medications and other healthcare items. Any medical
kit containing sharp objects, such as scissors or a scalpel, should be
in your checked baggage to avoid possible confiscation at an airline
security checkpoint. Medications and other items needed en route should
always be carried on your person.
-
An adequate supply of your prescription medications—Carry copies of your
prescriptions by generic names. Determine how much of each medication
you will need for the duration of your trip, and if you will need
refills. Check local availability of medications, but know that
regionally manufactured drugs may be substandard or counterfeit. The
illicit market in bogus, copied, relabeled, adulterated, and look-alike
drugs is burgeoning; therefore, be careful. It may be prudent to bring
enough medications for your entire trip—or make arrangements for
additional drugs to be shipped to you from home.
-
Antibiotics for treating travelers’ diarrhea—Fluoroquinolone antibiotics are
currently the most effective drugs and include levofloxacin
(Levaquin) and ciprofloxacin (Cipro).
-
Azithromycin (Zithromax) is the
best alternative treatment for travelers' diarrhea. It is the drug of
choice for treating travelers' diarrhea in children. Rifaxamin is a new antibiotic effective against E.
coli (ETEC-see Chapter 6). Ciprofloxacin and azithromycin are available
in liquid forms for children.
-
Antibiotics for self-treatment of other infections—The
fluoroquinolone levofloxacin (or ciprofloxacin or moxifloxacin) and
azithromycin are good choices but no one drug covers every illness.
The fluoroquinolones are effective against acute bacterial
bronchitis, community-acquired pneumonia, urinary tract infections, typhoid fever,
skin infections (cellulitis), and nongonococcal
urethritis. Fluoroquinolones may not be
effective against methicillin-resistant staph aureus (MRSA) skin
infections and are no longer recommended for treating gonorrhea.
Azithromycin is a good choice for respiratory infections and is also
effective against typhoid and cholera.
-
Azithromycin is
effective against sexually-transmitted diseases. A
single 2-g dose
of azithromycin is as effective against uncomplicated gonorrhea
as a 250-mg dose of ceftriaxone (but has more gastrointestinal side
effects). Azithromycin is also first-line treatment for chlamydia
infections.
-
Cefixime is now available in a 400 mg
tablet. A single 400-mg oral dose is effective for the treatment of
uncomplicated gonorrhea. The combination of 400 mg single-dose cefixime and single 1-g dose azithromycin is
virtually 100%
effective against mixed gonorrhea/chamydia infections. Travelers
who contemplate possible unprotected sexual exposure may wish to
carry these drugs for self-treatment.
-
Loperamide (Imodium-AD, Diamode)—Use to treat mild to moderate
travelers’ diarrhea, or use in combination with an antibiotic to treat
more severe diarrhea.
-
Antimalarial drugs—Recommended
especially if you are going to sub-Saharan Africa—an area where falciparum malaria is a
major threat (see Chapter 7). These drugs are usually
taken for prophylaxis; occasionally, they are carried for
self-treatment.
-
Medical kit—At a minimum, carry a basic first-aid kit that contains a
thermometer, Band-Aids, gauze pads, 1 or 2 roller gauzes, antibiotic
ointment, scissors, and tape. Blister pads (Spenco, moleskin) should be
included. The size of the medical kit depends on the number of
travelers, length of stay, and the availability of local health care.
Some travelers (especially those with multinational corporations) also
carry kits with suture supplies and intravenous fluids.
-
Sterile needle/syringe
kit—Recommended when traveling to countries where
hepatitis B, hepatitis C and HIV can be transmitted by nonsterile
medical injections or surgical procedures.
-
Water filtration/purification
supplies—MicroPūr tablets,
Katadyn filter, and the
Exstream water
purification bottle are popular.
-
Oral rehydration salts (e.g.,
CeraLyte)—Use to treat dehydration caused
by severe diarrhea. A 1- liter plastic bottle is adequate for storing
water or rehydration solution.
-
Epinephrine kit—If you have a history of severe bee sting reactions or
severe food or drug allergies, have your doctor prescribe an emergency
epinephrine self-injection kit (EpiPen). Be sure you know how to use it before you
leave.
-
Analgesics, such as ibuprofen (e.g., Motrin, Advil) or acetaminophen
(Tylenol)—Acetaminophen with codeine, or with hydrocodone (Vicodin),
also has antidiarrheal properties. Aspirin can lose potency when exposed
to humidity and heat. Acetaminophen is not affected by these conditions.
-
Antacids—Maalox or Mylanta are useful.
-
Pepto-Bismol—Useful for the prevention and treatment of diarrhea
(Chapter 6).
-
Cathartics and/or stool
softeners. Constipation can be a problem in elderly travelers.
-
Motion/sea sickness
drugs—TransDerm Scōp
patch (for sea sickness on cruises); SCŌPACE (scopolamine tablets),
Dramamine, and Phenergan are shorter-acting agents.
-
Drugs to prevent or treat altitude illness (see
Chapter 15)—These should
be considered when ascending above 8,000 feet.
-
Jet lag—Sleeping pills, e.g., triazolam (Halcion) are helpful for some
people who find insomnia the most troublesome symptom of jet lag.
Zolpidem (Ambien), zaleplon (Sonata), and
eszopiclone
(Lunesta) are alternatives. Melatonin has limited effectiveness, and is
not approved by the FDA for this indication.
-
Contact lens wearers—Antibiotic eye drops containing a
fluoroquinolone
(levofloxacin or ciprofloxacin) for treating an infected corneal ulcer
should be carried. Untreated bacterial infections can cause corneal
scarring.
-
Hand sanitizer gel or disinfecting skin towelettes—These are convenient
when soap and water are not available. Good hand hygiene helps prevent
the transmission of travelers’ diarrhea; hand sanitizers also kill
viruses that spread respiratory infections.
-
Nasal decongestant spray—Afrin or Neo-Synephrine.
-
EarPlanes—Pressure-regulating earplugs will reduce pain associated with
air travel. Especially recommended if you have trouble clearing your
nasal passages during flight.
-
Antihistamine tablets—Useful for allergic reactions and rhinitis (hay
fever). Zyrtec and Claritin-D are long acting and less sedating. Check
with your pharmacist about any possible drug interactions with
medications you may be already taking for a chronic condition.
-
VōSol
solution (2% acetic acid)—This prevents or treats swimmer’s ear.
-
Corticosteroid cream, such as Cortaid or Topicort—The steroid creams
available by prescription are more effective for treating rashes than
the over-the-counter products.
-
Antifungal foot powder—Lotrisone and Tinactin are good choices. These
are essential when traveling in the heat and humidity of the tropics.
-
Antifungal tablets—A single, oral 150-mg tablet of fluconazole
(Diflucan) will eradicate a vaginal yeast infection. (These infections
can result from using an antibiotic.)
-
Extra pair of prescription glasses or contact lenses—Bring a copy of
lens prescription.
-
Other useful items:
-
Other useful items: Tweezers (good for tick
and splinter removal), small knife, scissors, or Swiss Army
knife (keep out of carry-on luggage). Large safety pins often come in
handy.
For Rain, Sun, Heat, and Insects
-
Hat, sunglasses, umbrella
-
Sunscreens—Broad-spectrum sunscreen, minimum SPF 30.
-
Insect repellent—Important when traveling to a country where
insect-transmitted diseases, such as malaria, are a threat. Travelers
should use a skin repellent that contains at least 30%
DEET. A good
choice is
Ultrathon, which provides 12-hour protection against
mosquitoes, as well as ticks and biting flies.
-
Clothing insecticide—Permethrin is an insecticide that kills insects
that touch the treated fabric (e.g., clothing, gear, tents, mosquito
nets). Against ticks, it is more effective than
DEET. When used in
combination with a
DEET repellent (as is done by the U.S. military), up
to 100% protection against mosquito and tick bites can be achieved.
-
Mosquito bed net (preferably
permethrin-treated)
-
Insecticide spray (e.g., Raid Flying Insect Spray) to rid sleeping
quarters of night-biting insects

Checking the Weather at Your Destination
Global Weather Information:
http://weather.yahoo.com/
Adequate pre-trip planning is essential. If you’re on an adventure
itinerary, determine what exposure you will have to heat, cold, or
altitude. If you are on a trek, most tour organizers will advise you of
what to bring, but you may need to consult experts in outdoor/wilderness
travel to determine if what is recommended is truly adequate. A
Comprehensive Guide to Wilderness & Travel Medicine, 3rd ed., AMK
Publishers, Oakland, CA 2000, by Eric A. Weiss, M.D., is a recommended
resource and can be ordered from the publisher (Adventure Medical Kits:
800-324-3517) or
amazon.com.
Checklist for campers, hikers, and trekkers—You need to anticipate
sudden changes in weather, in particular, high winds, rain, and
temperature drops. For your comfort and safety, be sure always to carry
an outer shell or parka that is waterproof and breathable, fleece vest
or jacket, cap and gloves. Multiple layers of clothing should be worn in
more extreme conditions. Review the following checklist for additional
items your trip may require.

Shipping my Luggage and Other Stuff
You may want to unburden yourself of
bringing
heavy, bulky suitcases, sports equipment, or other items with you. There are several
companies who will ship ahead for you:

Passports—The Bureau of Consular Affairs’ website
(http://www.travel.state.gov) provides comprehensive information about
applying for, or renewing, a passport or visa. Passport application
forms can be downloaded from this site.
What if I need a passport in a hurry, or I have lost my passport?
Normally, it takes about 6 weeks to get your passport from the U.S.
Passport Agency. The Passport Agency will expedite the process for an
additional $60 (subject to change), plus overnight shipping, and your
passport will arrive in about 2 weeks. Passport/visa service companies,
however, can obtain a passport for you in as little as one business day,
plus overnight shipping. This assumes you have all your documents in
order. Also, if this is a first-time passport, the application must be
witnessed and sealed by an authorized passport acceptance agent (found
at federal, state and probate courts, post offices, some public
libraries, and a number of county and municipal offices) before the
passport/visa service company is able to process the application. This
expediting can be expensive—you pay the passport government’s passport
fee, plus as much as $180, plus shipping for next-day service. Standard
expedited service (6 to 9 business days) is about $60 plus the other
charges. Contact one of the following:American

Q. WHAT
SHOULD A U.S. CITIZENS DO IF THEIR PASSPORT IS LOST OR STOLEN
ABROAD?
A. Contact
the nearest
U.S. embassy or consulate
for assistance. Phone numbers for U.S. embassies and consulates
are also available in our
Consular Information Sheets
and
Key Officers handbook.
You will need to speak to the American Citizens Services unit of
the Consular Section. If you are scheduled to leave the foreign
country shortly, please provide the Consular Section with
details regarding your departure schedule. Every effort will be
made to assist you quickly. You will also be directed to where
you can obtain the required passport photos.
If you are
notified by a relative or friend that their U.S. passport has
been lost/stolen, you may wish to contact
Overseas Citizens Services
, (202) 647-5225 at the U.S. Department of State in Washington,
D.C. providing as much information about possible about the
person's who needs passport services abroad. This will assist us
in trying to verify the person's previous passport, clearing the
person's name through the Department Passport Name Check System,
and relaying this information to the U.S. embassy or consulate.
Your relative/friend must apply for a new passport at the
nearest U.S. embassy or consulate.
Q. WHAT
ARE THE REQUIREMENTS TO OBTAIN A REPLACEMENT PASSPORT?
A. You
will need to complete a new
passport application .
The consular officer taking an application for replacement of a
lost, stolen, or misplaced passport must be reasonably satisfied
as to your identity and citizenship before issuing the
replacement. In virtually all cases this can be done through
examination of whatever citizenship and identity documents are
available, conversations with the applicant, close observation
of demeanor and replies to questions asked, and discussions with
the applicant’s traveling companions or contacts in the United
States. Please note the
new requirements for passports for
minors under the age of 14 and how this will change
the way passport applications for minors are handled abroad.
Q. WHAT
INFORMATION WILL I NEED TO PROVIDE THE CONSULAR OFFICER?
A. You
will be asked for certain information to assist in verifying
your citizenship:
Personal Data: (including, but not limited to)
If you can
provide the U.S. embassy or consulate with a photocopy of your
passport identification page, that will make getting a new
passport easier since your citizenship and identity information
would be more readily available.
Affidavit Regarding Loss/Theft of the Passport/Police Report:
When you
report the loss, theft, or misplacement of your passport you
must execute an affidavit fully describing the circumstances
under which it was lost, stolen. U.S. Department of State form
DS-64 may be used for
this purpose, or you may simply execute a sworn statement before
the consular officer describing what happened. A police report
is not mandatory but may be required when the embassy/consulate
believes a problem may exist such as possible fraud. An
applicant eligible to receive a passport should not be placed in
circumstances to miss a plane or unreasonably delay travel to
obtain a police report.
Citizenship Verification and Name Clearance:
The U.S.
embassy/consulate will confirm your previous passport issuance
through the Passport Verification System. The consular section will also
attempt to clear your name through the U.S. Department of State
name check system to ensure there is nothing preventing issuance
of a U.S. passport to you (for example: outstanding arrest
warrant, court order, etc.)
Proof
of Identity:
You will
also be asked for some proof of your identity. If all your
personal papers were lost or stolen with your passport, your
identity can be established in a number of ways. In most cases
the problem of identity is resolved quickly. It should be noted,
however, that if there is any indication of possible fraud the
consular officer may request additional documentation or other
information.
Information From Consular Interview: The consular officer may be
satisfied as to your identity based on the interview with you,
or may require other information.
Identifying Witness: Persons traveling with a group or with
friends, family or associates in the foreign country can have
such a person execute an affidavit of an identifying witness
before the consular officer. An identifying witness does not
have to be a U.S. citizen.
Information From Family, Friends or Associates in the United
States: If you are traveling alone and do not know anyone in
the foreign country who can attest to your identity, your
family, friends, or associates in the U.S. may contact the
consular officer by phone or fax confirming your identity. This
is usually quite informal. In emergency situations, your
contacts may also communicate with the U.S. Department of State,
that
Overseas Citizens Services
, (202) 647-5225.
Information From Previous Passport Records: If necessary,
information about your identity may be obtained from your
previous passport application which may have to be retrieved by
Overseas Citizens Services
, (202) 647-5225, in the U.S. Department of State from the
Federal Records Center which is located outside of Washington,
D.C.
Q. WILL
THE REPLACEMENT PASSPORT BE ISSUED FOR THE FULL 10-YEAR VALIDITY
PERIOD FOR AN ADULT?
A.
Replacements for lost passports are normally issued for the full
10-year period of validity for adults. Occasionally, cases will
arise in which the consular officer has some lingering doubt
because of statements made by the applicant, or other
circumstances, but is still reasonably satisfied as to identity
and citizenship. If there is not time to request and receive the
Department’s verification, a passport limited to 3 months may be
issued. Limited passports may also be issued in cases in which
an applicant has, by mistake, packed the passport with luggage
being sent to another location, left the passport at home,
perhaps in another country, but has to travel immediately, lost
or been robbed of multiple passports in a short timespan, etc.
When issuing a limited passport in an emergency situation,
consular officers will carefully explain to the applicant that
the passport is limited for the duration of the present trip
only. When the applicant returns to the United States and wishes
to travel again internationally, the applicant will have to
apply for a replacement passport and pay the regular fee.
Q. ARE
FEES CHARGED FOR REPLACEMENT OF LOST/STOLEN PASSPORTS ABROAD?
A.
The normal passport fees are collected from applicants for
replacement passports. Applicants will be asked to provide names
of persons they feel would be able to assist them financially if
there is sufficient time. See our information about Financial
Assistance to U.S. citizens abroad and Learn About Sending Money
Overseas to U.S. Citizen in an Emergency.
However,
if: the
applicant’s money and documents have been lost or stolen, or the
applicant is a victim of a disaster and the
applicant does not have and cannot reasonably be expected to
obtain money to pay the fees before continuing travel, no
passport fee will be charged and a limited validity passport
will be issued. When the person applies for a full validity
passport on their return to the United States the regular
passport fee will be charged for the replacement passport. See
the
U.S. Department of State Schedule of
Fees, 22 CFR 22.1
|
Q. CAN THE
U.S. EMBASSY ISSUE A REPLACEMENT PASSPORT OVER A WEEKEND OR
HOLIDAY?
A. U.S.
passports are not routinely issued by U.S. embassies and
consulates abroad on weekends and holidays when the
embassy/consulate is closed. All U.S. embassies and consulates
have an after hours duty officer available to assist with life
or death emergencies of U.S. citizens abroad. Contact the
nearest
U.S. embassy or consulate after hours duty officer for assistance if you have an emergency
need to travel. Phone numbers for U.S. embassies and consulates
are also available in our
Consular Information Sheets and
Key Officers handbook.
If you are
scheduled to travel directly to the United States, the duty
officer may be able to assist in issuing a transportation letter
to the airline and alerting U.S. Customs and Immigration to the
fact that you will be attempting to enter the United States
without a passport.Duty
officers must focus primary attention on life or death
emergencies. Depending on the circumstances and conditions in
the foreign country, it is possible that a replacement passport
may not be issued until the embassy/consulate reopens for
business. At that time the Consular Section will be in a better
position to verify your citizenship and identity and clear your
name through the Department of State name check system.
|
· Visas—The best source to obtain up-to-date visa requirements for travel
to other countries is the website of the Bureau of Consular Affairs
(http://travel.state.gov/travel/tips/brochures/brochures_1229.html).
After verifying the need for a visa, contact the embassy or consulate of
the country or countries of your destination to verify information
regarding the documents you will need and the processing time required.
You can also use one of the passport expeditor companies listed on the
previous page to file the application. Go to their websites to view the
process and fees.
· HIV testing requirements for entry into foreign countries—Not
all
HIV testing
requirements are found on the U.S. Department of State website, or the requirements may have changed, so
check with the embassy or consulate of the country that you plan to
visit to verify the requirement for entry, if any. The HIV test is
usually required only for those applying for a foreign work permit,
prolonged residence, or immigration—not for tourist visits of less than
1 to 3 months. Tests done in the United States or Canada may not be
accepted..
· International Certificate of Vaccination (Yellow Card)—Yellow fever
vaccinations must be given at official Yellow Fever Vaccination Centers
(e.g., a travel clinic, local health department) as designated by
respective state health departments. The international certificate of
vaccination (the Yellow Card-pictured below) must be validated with the “Uniform Stamp”
and signed by the physician or the physician’s designee. The Centers for
Disease Control and Prevention website (www.cdc.gov/travel)
lists all the authorized
Yellow Fever
Vaccination Centers within the United States, by state, that are
licensed to administer the yellow fever vaccine and the certificate of
vaccination.
You need to have in your possession a validated International
Certificate of Vaccination when
entering
countries that require proof of yellow fever vaccination.
Some countries in sub-Saharan Africa require ALL travelers to have a
valid Certificate, but for most countries the requirement is only if you
are arriving from an infected area or from any country in the yellow
fever endemic zones. The
Certificate of Vaccination becomes valid 10 days after the
immunization is administered. Be sure to take this lag period into
account.
You
should carry the yellow card with your passport.
Newly revised in 2007, the new
International Certificate of Vaccination is approved by the World Health
Organization as the official document verifying that proper procedures
were followed in administering vaccinations for foreign travel. It is
used to demonstrate receipt of required vaccinations for entry into
foreign countries, and is designed to fit into a passport. In addition,
the International Certificate of Vaccination is used to record the
following information:
- Date and dose of all vaccinations
received for foreign travel
- Medical exemption from receipt of
required vaccinations
- Personal health history
- Drug allergies
- Current medications
- Prescriptions for eyeglasses or
contact lenses
Note: Currently no country “officially” requires cholera vaccination as
a condition of entry. Local authorities in some (usually sub-Saharan)
countries, however, may require documentation of vaccination. This
tactic may be used to extract a bribe to waive the “requirement.”
Depending on your itinerary (and because the cholera vaccine is no
longer available in the United States), you may have your health-care
provider state on your Yellow Card “Exempt from cholera vaccine” and
have the exemption stamped and signed. Note:
There is no section for cholera vaccination on the new Yellow Cards.
Some travel clinics routinely state that the vaccine is contraindicated;
in some cases the clinic will create a cholera stamped area while being
sure that the traveler knows that they did not receive the injection.
· Extra photos—Obtain at least eight (8) additional 2¢¢
´
2¢¢
photos when applying for your passport or visa(s). These extra photos
will come in handy if you need additional visas or an international
driver’s permit or if you need to replace a lost passport or other
document.
· Personal health records—Consider carrying photocopies of your health and
hospital records, recent electrocardiogram (ECG), laboratory test
results, list of current medications, allergies, etc. Or, you may wish
to subscribe to a service that can assemble all of your pertinent
medical records, store them in a computer, and fax or e-mail them
anywhere in the world within minutes. Contact Global Med-Net
(800-650-SAVE) for further information. Another resource is
Traveler-ER. They
sell a USB device that stores emergency contact and personal
health information and which does not, for security reasons, rely on any
central database.
· Travel health insurance—It is always a good idea to purchase a travel
insurance policy (Chapter 18). These policies pay overseas doctors and
hospitals at the time of the visit, and they also cover emergency
medical transport. Check your existing health insurance policy to see
what benefits are provided in case of illness overseas. Normally, only
emergencies are covered. Medicare does not pay for out-of-country
illnesses or accidents, so anyone with Medicare should also have MediGap
coverage.
· Doctors and hospitals abroad—The International Association for
Assistance to Travelers (IAMAT) publishes a booklet listing hospitals
and English-speaking physicians overseas. 417 Center Street, Lewiston,
NY 14092; 716-754-4883. The
Destinations Section of this website has extensive country listings
of doctors and hospitals, with many website addresses.
· Medic Alert bracelet—If you have a serious or chronic medical condition,
a history of severe drug allergy, etc., you should consider wearing a
Medic Alert bracelet. Call 1-800-ID-ALERT to order.
· Prescription drugs abroad—Worldwide delivery of non-controlled
(non-narcotic) medications sent via Federal Express or DHL. Contact:
Global RX, 4024 Carrington Lane, Efland, NC 27243; Tel: 919-304-4278;

· Divers Alert Network (DAN)—For non-emergency medical questions and
general information, scuba divers can call (919) 684-2948 for DAN’S Dive
Safety and Medical Information Line. (Website:
www.diversalertnetwork.org).
For scuba diving emergencies, DAN’S Diving Emergency Hotline is (919)
684-4DAN (4326) or (919) 684-8111. These lines are open to all divers.
· Telephone number and e-mail address of your personal physician
or medical group
· Foreign language telephone assistance—When dealing with medical problems
long distance, there may be language barriers. Call AT&T’s Language Line
at 800-628-8486 for assistance. The service costs vary per minute,
depending on the language being interpreted.
· Traveler’s checks—Make a photocopy of the numbers. Leave the photocopy
at home and carry with you the list of numbers that you get with the
checks. Copy the date and place of purchase and where to call if the
checks are lost or stolen.
· Credit cards—Know your charge card credit limits. U.S. citizens have
been arrested in some countries for exceeding credit limits. Keep a copy
of your card numbers in case they are lost or stolen. Report the loss
immediately.
· Money—ATM facilities in other countries are becoming more prevalent;
they offer convenience and usually the best exchange rates. Foreign
banks usually will advance cash against your credit card. Be sure you
have your PIN number.
· Birth certificate and photo ID—These documents can sometimes be used in
lieu of a passport for entry into certain countries. They’re also useful
to have if you lose your passport. If you are living overseas or getting
married in a foreign country, be sure to have these documents with you.
· Green card for resident aliens—Don’t leave home without it.
· Doctor’s letter—You may want a doctor’s letter describing and
authorizing the prescription medications you will be taking on your
trip, including needles/syringes
if you are a diabetic. The letter should contain the generic names of
the medications and the dosages.
· International driver’s permit—This is available at any AAA office. When
applying you’ll need two passport-sized photos (they can take the
photos), your driver’s license,
and $15 for the fee. The international driver’s permit is printed in
nine languages and serves as a translation for your license, which is
valid in many countries. Note: You also need to take your regular
driver's with you when you drive abroad. A few countries (China, Egypt, Nepal) do not
allow tourists to drive.
· Notarized parental consent—Necessary when a minor child is traveling
with the noncustodial parent. This permission letter may even be
required when one parent is traveling internationally alone with his/her
child. You may not be able to board the aircraft or enter a country
(e.g., Mexico) without this document.
· Mobile phones overseas—Unless you have a multi-band GSM phone, your own
mobile phone (cellphone)) is probably useless overseas, so you may want
to buy or rent a phone for your trip. A low-cost option is buying a
cheap, prepaid phone on arrival. You can also buy a phone before
departure, or at your destination, whose SIM card can be reloaded with
airtime purchased locally. Good resources for mobile phones overseas
include Telestial (www.telestial.com) and Cellular Abroad (www.cellularabroad.com). NOTE: Camera phones are not allowed in Saudi Arabia
and their use in some other countries may arouse suspicion.

Avoiding a Large Phone Bill When
Traveling
By DAVID A. KELLY
UBIQUITOUS connectivity has its downside, especially when it comes
to the price of using your cellphone abroad. The proliferation of
smartphones and the increased use of data have made it easier than
ever to rack up huge communications bills while traveling overseas,
even on a short trip.
“Many leisure travelers with iPhones are going to
Europe, not turning off their data and allowing their apps to
continue downloading data,” said Ken Grunski, chief executive of
Telestial, a company that provides wireless services for travelers.
“U.S. travelers were already getting hammered with expensive voice
calls that start at $1 per minute. I know of people that have
returned home to $1,000 or more roaming bills.”
Luckily for tech-savvy travelers who want to stay in touch, there
are ways to avoid spending a small fortune. Here are some options.
Getting the Right Phone
Many countries outside the United States rely on a wireless
network technology called GSM. But two major American carriers —
Verizon and Sprint — use different technologies in most of their
standard phones. Owners of those devices will need a special
cellphone when traveling to many countries.
Verizon users have a fairly convenient way to deal with this
problem. If you’ve been a subscriber for six months or longer,
Verizon will lend you a global phone free of charge for trips of 21
days or less; the customer pays only the two-day
FedEx fee of $9.99.
Once you receive the phone, call Verizon to activate it and
select an international rate plan (with the $4.99 a month plan, a
call from, say, France, will cost 99 cents a minute compared with
$1.29 without the plan; texts, which cost 50 cents per message sent
and 5 cents per message received, are not included). After the trip,
just ship the phone back.
AT&T and T-Mobile have GSM networks, so many of their standard
phones will work overseas, although you’ll still need to sign up for
an international roaming plan to keep rates down. For example, with
the $5.99 a month AT&T plan, calls from many Western European
countries to the United States are only 99 cents. A package of 50
roaming texts costs $10.
Another option is to buy an inexpensive travel phone from a
company like Telestial (telestial.com)
or Planet Omni (planetomni.com).
They typically cost less than $50. For example, Planet Omni’s Kit
V520 ($49) offers a dual-band GSM phone, SIM card with both a United
States phone number and a global phone number, and $5 in airtime.
The service allows you to receive free incoming calls in France,
Italy, Spain and Britain on the global number, and free voice mail
in 60 countries. Costs for outgoing calls depend on the country. For
example, an outgoing call from France to a United States landline is
99 cents per minute, while a call to a mobile phone is $1.49 per
minute. Telestial’s Passport package (starting at $99) provides free
incoming calls in Europe, as well as calls back to the United States
for 49 cents per minute.
Data Deals
With everything from Internet radio to online maps to multitudes
of apps, iPhones and smartphones can consume huge amounts of data.
It might not be a big deal at home, but using all those apps on the
road can add up quickly. If you plan on using a lot of data services
while traveling, make sure you check with the carrier to see if it
offers international data roaming plans.
For example, AT&T offers data roaming plans for the
iPhone and smartphones that provide 20 megabytes of data usage
within 90 countries for $24.99 per month, and up to 200 megabytes
for $199.99 per month.
These charges are in addition to whatever your usual monthly
charge is in the United States, but the cost pays off if you use a
lot of data, especially when you consider that the standard
international roaming rates for many Western European countries are
about $20 per megabyte (according to Mr. Grunski, of Telestial, some
Web pages are half a megabyte, so downloading, say, five pages in a
single day could cost you $50 without a plan).
In addition, AT&T recommends that iPhone users go to their
settings and turn off data roaming and options to fetch new data.
They should also reset their usage tracker to zero so they can keep
an eye on new charges, and make sure to use Wi-Fi instead of their
phones’ 3G services to check e-mail messages or use the Web.
SIM Cards
Frequent travelers may want to consider another money-saving
technique: replacing a phone’s American SIM card (the little
electronic memory card that identifies and configures your phone)
with a local (or country-specific) SIM card. In general, when you do
that, all incoming calls will be free and outgoing calls (local or
international) can be significantly cheaper.
Be aware that replacing the SIM card means that your phone has a
different number, so you may want to let your contacts know, or set
your phone to forward all calls to the new number before you go.
Your phone also has to be unlocked so it can work with other
carriers’ networks — your cellphone company can provide information
on how to do this — and it needs to be compatible with the wireless
services in the country you’re visiting.
“Even with an international roaming package on AT&T, it can cost
99 cents a minute or more for voice calls,” said Philip Guarino, an
international business consultant and founder of Elementi Consulting
in Boston. “The moral of the story is, dump your American SIM card
and buy a local one instead.”
When Mr. Guarino travels he simply buys a SIM card at his
destination airport and uses it for cheap local calls.
“In a pinch, even if I call directly from my phone using a
foreign SIM card, the average direct-dial rates are about 60 cents
U.S. per minute, which is cheaper than using my original U.S. SIM,”
he said.
The VoIP Option
Internet-based voice services (VoIP) such as Skype (skype.com)
or Truphone (truphone.com),
which charge as little as 2 cents for calls to regular phones, are
among the cheapest ways for international travelers to communicate.
This spring, Skype announced support for the iPhone, allowing iPhone
users to make or receive Skype calls over either Wi-Fi or 3G
connections.
One good option for travelers wanting to use Skype or Wi-Fi while
traveling is Boingo Wireless. For $7.95 per month, travelers can
sign up with Boingo (boingo.com)
for unlimited Wi-Fi access in hotels, restaurants, cafes, airports
and more in over 70 countries. Coupled with Skype or a similar VoIP
product on an iPhone, smartphone or computer, it’s hard to beat the
value.
Last, but Not Least
Don’t forget the old-fashioned calling card. When Mr. Guarino
travels, he often uses discounted international calling cards from
local cafes or newsstands.
“The rates to the U.S. are about 3 cents per minute, plus the
cost of the local call,” he said. “It’s a good option for making a
call from a land line, especially if you have a conference call to
make where you don’t want to worry about call quality.”
More
About Mobile Phones Overseas (NY Times):
As a T-Mobile
subscriber, Ken Grunski, a businessman in San Diego, knew that his
cellphone would work during a trip to Tanzania. What he did not expect
was the bill: $800 for 10 days’ use. “I didn’t think I was
going to use my phone that much,” Mr. Grunski said. “But two to three
10-minute calls a day, and it adds up.”
What a shame that Mr.
Grunski did not heed his own company’s advice. If he had, he would have
saved himself a bundle. Mr. Grunski owns
Telestial, a company that sells SIM cards, small chips that replace
those in cellphones sold by T-Mobile and Cingular and lower the costs of
calls when overseas.
While his American
phone worked abroad without one, Mr. Grunski was paying sky-high rates
because he was roaming in a foreign country. T-Mobile charged him $5 a
minute to roam in Tanzania. If Mr. Grunski had
used one of the SIM cards he sells, he would have paid $1.15 a minute to
call the United States and his calls — averaging 16 minutes a day —
would have cost him $184, rather than $800.
While Americans have
embraced the convenience of using cellphones, trying to dial from
overseas often brings surprises. Even if the phone works, voice mail may
not. Depending on the handset, coverage can be spotty. Make the wrong
choices, and you may find a huge bill.
The right tactics to
avoid those headaches depend on which carrier you use, the length of
your trip and your destination.
A majority of the
world’s cellphone subscribers — 82 percent — use the GSM technology
standard, according to the GSM Association. In the United States, the
major carriers use two systems. Cingular (now
AT&T)
and T-Mobile use GSM, while
Sprint
and
Verizon
use CDMA, an incompatible technology.
CDMA technology is
found in North America, as well as some Asian countries, but it is
basically nonexistent in Europe, Australia and South Africa. As a
result, Sprint and Verizon customers can use their phones in just 26
countries. (AT&T and T-Mobile customers can potentially use theirs in
over a hundred.)
When traveling in
non-CDMA countries, Sprint and Verizon customers can rent or purchase
GSM phones from those providers. Sprint rents a
Motorola Razr
for $58 for the first week, and $70 for two weeks, plus $1.29 to $4.99 a
minute of airtime. Verizon charges $3.99 a day to rent, plus $1.49 to
$4.99 a minute. Verizon also sells three combo CDMA-GSM models, priced
from $150 to $600 with a two-year contract.
Cingular and T-Mobile
customers have more options — if their existing phones can pick up
multiple frequencies. To complicate matters, the American GSM standard
operates on 850 and 1,900 megahertz, while the rest of the GSM world
uses 900 and 1,800 megahertz.
To use an American GSM
cellphone in a foreign country, the handset you own must be tri-band or
quad-band and able to operate on one or both of the frequencies used
outside the United States. The Cingular and T-Mobile Web sites, as well
as Telestial’s and others, list the predominant frequencies used in each
country, and show if your phone can operate on one or both overseas
bands.
To protect against
fraud, American cellphones are typically blocked from making calls when
used abroad. Before traveling, call your provider and ask to have that
restriction removed.
A Temporary SIM Card
GSM phones use SIM
cards (subscriber identity modules), tiny electronic chips that hold a
cellphone’s “brains,” including the subscriber’s contact numbers and
phone number. (CDMA phones store such information directly in the
hardware.)
GSM customers can
avoid sky-high roaming charges by replacing their American SIM cards
with ones from other countries. For example, travelers to Britain can
pick up a SIM card from the British carrier
Vodafone; once inserted, it gives
the phone a temporary British phone number. Calls within Britain and to
the United States would be much cheaper.
For example, T-Mobile
charges its customers $1.99 a minute for using their phones in Britain,
whether calling a pub in London or your home in New Jersey.
Insert a prepaid
British SIM card instead, and local calls drop to 26 cents a minute,
while calls back to the United States cost 9 to 14 cents a minute.
Another benefit when
using overseas SIM cards is that incoming calls are typically free in
most countries.
Overseas SIM cards can
be purchased before you travel from companies like Cellular Abroad (www.cellularabroad.com)
and Telestial (www.telestial.com)
or at local shops in foreign countries.
Unlocking the Phone
Even if you have a GSM
phone that operates on both overseas frequencies, domestic cellphone
providers do not want you to use your phone with another company’s SIM
card, because they do not make any money when you do. To prevent your
doing so, cellphones bought through Cingular and T-Mobile are
electronically locked — they accept only their own company’s SIM cards.
Before you throw your
phone off the Eiffel Tower in frustration, know that there are several
ways to unlock your phone and avoid those high overseas roaming rates.
Cingular and T-Mobile
will unlock their customers’ phones under certain conditions. Cingular
will provide unlock codes to customers whose contracts have expired, who
have canceled their service and paid an early termination fee, or who
have paid a full rather than subsidized price for their phones,
according to Rich Blasi, a Cingular Wireless spokesman.
T-Mobile has more
lenient policies. It will provide the unlock code to any customer after
90 days of service, but no more than one unlock code will be provided
every 90 days, said Graham Crow, a T-Mobile spokesman.
If you do not meet
these requirements, you can still get your phone unlocked from a private
company. For a few dollars, the Travel Insider (www.thetravelinsider.com)
and UnlockTelecom (www.unlocktelecom.co.uk)
will provide your phone’s specific unlocking code.
Other GSM Phones
Cellphone customers
with dual-band GSM phones that cannot be used overseas can always
purchase unlocked quad-band phones from third-party providers. These
phones can be used solely when traveling outside the United States.
Since they are unlocked, they can also be used instead of your current
phone on your American network.
Because the phone is
not subsidized by a carrier, the price is higher. For example, an
unlocked quad-band Motorola Razr V3 can be bought for $140 from Cellular
Blowout (www.cellular-blowout.com).
Cellular Abroad and Telestial also sell unlocked phones.
A Few More Tips
When entering numbers
in your phone, always add the plus (+) sign and the country code; that
way, the number can be dialed automatically no matter from what country
you are calling.
Store your GSM phone’s
numbers in the phone itself, rather than the SIM card. Then the numbers
will still be available to you when you use an overseas SIM card. To
transfer them to a new phone easily, store them on a device like
Backup-Pal (www.backup-pal.com),
an external U.S.B. memory unit.
While you will not pay
any charges for incoming calls when you use a foreign SIM card, tell
your American callers to get an overseas calling plan from their phone
company before you ask them to ring you. If they do not, they could be
paying the same sky-high rates that you just avoided.
And if you take your
American phone overseas, make sure that its battery charger is dual
voltage; without one, all the effort to get your phone to work in other
countries may go up in smoke the first time you plug it in.
Vaccinations
See Chapter 3 for travel vaccination guidelines.
TRAVELERS WITH SPECIAL
NEEDS
If you have a history of coronary heart disease, and your condition is
stable, travel is generally low risk, and airline travel is considered
safe. Heart disease, per se, is not a contraindication for travel to
high altitudes (see Chapter 15, Altitude Illness). No matter where you
go, be sure you have:
Pacemakers A pacemaker or an implanted defibrillator/cardioverter
(AICD)
is not a contraindication to air travel, and these devices are not
affected by walk-through airport security magnetometers. However, the
handheld security magnetometers should never be used on someone with an
implanted defibrillator. Electronic telephone checks of pacemaker
function cannot be transmitted by international satellite.
The cabins of commercial airlines are
pressurized to an altitude of 1524 to 2438 meters (5000 to 7998 feet).
Most healthy individuals tolerate this cabin pressure, but symptoms of
mild altitude sickness are sometimes reported (fatigue, headache,
lightheadedness and nausea) after three or more hours of flight.
If you have chronic obstructive pulmonary disease (COPD, emphysema), air
travel is considered safe if you can walk a block or climb a flight of
stairs without becoming breathless. In-flight oxygen may be indicated if
your sea level arterial oxygen saturation (Pao2)
on room air is 67 mm Hg or less or if the expected in-flight Pao2
is less than 50-55 mm Hg.
Starting in May 2009, Portable Oxygen
Concentrators must be allowed on all flights originating or ending in
the United States. This will require all airlines operating in the US,
including foreign airlines, to allow the use of approved POCs on-board
and in-flight.
If your doctor advises in-flight oxygen, contact the airline medical
department at least 48 to 72 hours prior to departure. There may be a
$50 to $75 charge for oxygen for each flight/plane
change. The airline will request a physician’s letter stating your
medical condition and a prescription for the oxygen. Be sure to carry
copies of these documents with you.
Portable Oxygen Concentrators (POCs) can be purchased or rented. If you
are interested in renting a POC for short term usage during travel you
should contact your regular oxygen supplier. Here are some other
companies which specialize in POC rentals.
If you take pills to control blood sugar, no time zone adjustment of
dosage is necessary when flying. Take your medication according to the
local time.
-
If you are a diabetic using insulin, take enough insulin and U-100
syringes to last the entire trip. (Many countries still use U-80
syringes.)
-
If traveling by air, call the carrier 72 hours before departure to order
a diabetic menu.
-
Hand carry your insulin at airport security checkpoints.
-
Consider carrying all diabetic supplies in a specially designed case,
such as the DIA-PAK. Insulin will keep its full potency for several
months even if it’s not refrigerated, but its temperature should be kept
below 86°
F. The DIA-PAK (two models available) has a refreezable cold pack for
keeping insulin cool in hot climates. The company also carries glucose
gel pabrkets abbr other accessories. Contact B & A Products at
918-696-5998 or www.baproducts.com.
-
Test blood glucose at 6-hour intervals or before each meal during the
flight.
-
Carry sugar cubes, glucose gel, or a snack in case an insulin reaction
(hypoglycemia) occurs.

in-Flight Arterial Oxygen Tension from Cabin Altitude and Preflight
Arterial Oxygen Tension

Schedule a dental checkup—Allow enough time for corrective work. Avoid
dental work and injections in countries where HIV and hepatitis B
infections are threats. Consider carrying an emergency dental kit to
treat broken or lost fillings—a DenTemp kit (for example see Fig. 2.2.)
Figure 2.2 The Den-Temp dental repair kit
is available at most pharmacies

Check your feet—Proper foot care is essential, especially for hikers and
diabetics. Carefully trim nails, corns, and calluses. Use foot powder to
keep feet dry and fungus free. Be sure shoes and hiking boots are broken
in and fit properly. Don’t let a painful, infected blister or another
preventable foot problem ruin your trip or jeopardize your health.
Schedule an eye examination—Carry an extra set of eyeglasses.
Contact-lens wearers should also carry a pair of eyeglasses. Keep a copy
of your eyeglass prescription with you. Also, if you wear contact
lenses, carry antibacterial eye drops (Ciloxan, containing
ciprofloxacin, is a good choice). Contact-lens wearers, especially those
who wear their lenses overnight, are at increased risk for developing
bacterial keratitis (infected corneal ulcers, which may be caused by
Pseudomonas or Serratia bacteria). These infections may cause permanent
corneal scarring or perforation if not treated promptly. NOTE: Even
daily-wear soft contact lenses are three times more likely to cause
bacterial keratitis as are the daily-wear, rigid, gas-permeable lenses.
Pre-travel evaluation Pre-travel medical screening should include (just
as with all travelers) a medical history, immunization history, allergy
history, and a history of any problems during previous travel. Those
whose CD4+
cell counts are normal or greater than 500/mL are usually at no greater
risk than noninfected travelers for travel-related problems, but those
whose CD4+
cell counts are less than 200 cells/mL,
or who are symptomatic, are at a greater risk of acquiring infections.
Travelers’ Diarrhea In HIV-positive travelers, this disorder can occur
more frequently, be more severe, and be more difficult to treat.
Infections with Salmonella, Shigella, and Campylobacter species are more
protracted and more oftedn associated with bacteremia. The usual 1- to
3-day course of antibiotic treatment for travelers’ diarrhea may need to
be extended to 7 days.
Cryptosporidium, a common cause of diarrhea in the tropics, produces
severe chronic diarrhea, malabsorption, and, occasionally, inflammation
of the gallbladder (cholecystitis). Cyclospora parasites cause similar
symptoms. Isospora belli infections are also common and cause
malabsorption and weight loss. There is no apparent increased risk for
gastrointestinal infections caused by viruses, Entamoeba histolytica,
Giardia lamblia, or enterotoxigenic Escherichia coli (ETEC-the most common
cause of travelers’ diarrhea).
Other Infections Respiratory illnesses, such as bacterial pneumonia and
fungal infections (e.g., histoplasmosis and coccidiomycosis), cause
greater mortality in HIV-positive patients. Tuberculosis is a serious
risk for those living or working in lower socioeconomic populations in
the developing world. Short-term business travelers and tourists are at
low risk for acquiring tuberculosis. Visceral leishmaniasis is difficult
to diagnose and treat, and the mortality is high. Even short-term
travelers to Spain, southern Europe, and other risk areas have acquired
this illness. Increased severity of malaria has not been demonstrated
conclusively in HIV-infected patients, but this infection must be
prevented by chemoprophylaxis and insect-bite prevention measures.
Preventive Measures Food and drink precautions should be carefully
followed. Undercooked meat, fish, shellfish, eggs, raw and unpeeled
fruits, raw vegetables and salads, tap water, and unpasteurized dairy
products should be avoided. Hands should be washed, or a hand sanitizer
gel applied, before meals to reduce the spread of gastrointestinal and
respiratory diseases. Consideration should be given to giving
prophylactic antibiotics to short-term travelers with low CD4+
cell counts to prevent travelers’ diarrhea. All other travelers,
including those travelers taking prophylactic sulfa drugs to prevent
pneumocystis pneumonia, should carry a standby self-treatment course of
a quinolone antibiotic. Taking precautions against insect bites is
important to prevent diseases such as malaria, dengue, and
leishmaniasis.
Sexually Transmitted Diseases HIV-infected travelers should be counseled
against engaging in sexual behavior that might infect others or that
will increase their own risks of acquiring infections such as syphilis,
herpes simplex, or an intestinal microorganism. Hepatitis B is likely to
be more severe as is the chance of becoming a chronic carrier of the
virus.
Immunization (vaccination) All HIV-positive travelers should be
appropriately immunized, but the antibody response to immunization may
be impaired, especially when the CD4+
cell counts are less than 200 cells/mL. Increased doses of hepatitis B
vaccine, for example, may be needed in immunosuppressed individuals.
Because the antibody response to vaccines is higher in individuals with
early HIV disease and higher CD4+
counts, it is best to immunize such individuals at the earliest
opportunity. This applies to any HIV-positive person who contemplates
possible future travel, as well as any person who has imminent travel
plans. In general, live vaccines are contraindicated in those who are
symptomatic or who have low CD4+
cell counts.
Evaluation of Illness
Acquired Abroad
If you traveled abroad, you may be at risk for having acquired a
bacterial, viral or parasitic disease that becomes symptomatic after
returning home. You could also infect others close to you if you
unknowingly became infected with a disease such as tuberculosis, HIV, or
typhoid.
Fever is the most important post-travel symptom and should always be
carefully and promptly evaluated. Your doctor must determine if your
fever is caused by a travel-related illness or is due to an illness that
you acquired later. However, in about 25% of travelers, no cause of the
fever can be found, and it is assumed in these instances that the fever
is due to a self-limited viral infection.
Important Post-Travel Symptoms
The most common symptoms of a tropical or infectious disease are the
following:
Key point: If you become sick after returning home, ask your primary care physician to consult with a
travel medicine specialist - when the diagnosis is unclear - if there is any possibility that
your
illness might be caused by a travel-related or tropical disease.
Diagnosing the Cause of Fever
The length of time after returning home and the length of time after
possible disease exposure have diagnostic implications. Some diseases
cause symptoms only a few days after exposure, whereas others become
evident after weeks to months. Table 2.1 lists the most common travel-related
diseases with fever and their incubation periods.
Your travel itinerary helps the clinician determine what illness may be
causing the fever. Certain diseases, such as malaria, can immediately be
eliminated if they don’t exist in any of the countries you visited.
Also, being vaccinated against a disease makes it much less likely to
contract it. Consult the World Medical Guide in this book to see which
infectious or tropical diseases are present in the countries on your
itinerary. Then combine the knowledge of possible disease exposure
(e.g., insect bites, exposure to potentially contaminated food or water)
with the incubation period data in Table 2.1 to narrow the diagnostic
possibilities. Finally, laboratory testing can often clinch the
diagnosis.
For example, if you have returned from
sub-Saharan Africa and two to three weeks later develop a high fever, malaria
is probably the most likely diagnosis; however, if a blood count shows a
high percentage of eosinophils (a type of white blood cell), you may
have
Katayama fever, which is the initial phase of schistosomiasis,.another
parasitic disease.

THE POST-TRAVEL MEDICAL CHECKLIST
Although you might have traveled in countries where certain diseases
exist, this doesn’t necessarily mean you had any exposure; therefore, a
detailed history of your actual activities is essential to assess your
risks. Your immunization status is also important. Questions a clinician
should ask you are the following:
-
Your itinerary: What countries did you visit and for how long? Were you
in a disease-endemic area in that country?
-
Were you visiting friends or family?
-
What were your arrival and departure dates? When did you return home?
-
Which vaccinations did you receive prior to departure? For example, if
you were given the hepatitis A or yellow fever vaccine, these diseases
could virtually be eliminated as diagnostic possibilities. The typhoid
fever vaccine, however, is not 100% effective, so vaccination will not
entirely eliminate the risk of this disease.
-
Did you travel in rural areas of tropical/semitropical
countries?
-
Did you take measures to prevent insect/mosquito
bites?
-
Did you adhere to your malaria prophylaxis schedule (if prescribed) and
was the drug appropriate?
-
Did you adhere to safe food and drink guidelines? Did you eat snails,
crabs, prawns, raw fish, or inadequately cooked exotic foods made from
beef, pork, bear, walrus, or fish?
-
Did you have contact with sick people with respiratory illnesses, such
as tuberculosis?
-
Did you get sick during your trip? Were you treated by a doctor? Was
your illness diagnosed? What medications were you given? Did you receive
any injections or blood transfusions?
-
When was the onset of your post-travel symptoms—days, weeks, months,
after return?
-
What was your exposure to the following:
-
Unsafe food and drink—Did you eat undercooked or raw meat or fish (e.g.,
sushi); cold food from salad bars; street vendor food not piping hot?
-
Insect and animals bites—Were you bitten by mosquitoes, flies, or ticks?
Were you bitten by a dog or other animal?
-
Walking barefoot on beaches or moist soil?
-
Freshwater swimming, wading, or bathing?
-
Unprotected sex with a new partner?
-
Recreational drugs (especially by injection), tattooing, body piercing,
or plastic surgery procedures?
-
People with infectious diseases?
Table 2.3 Laboratory Tests
| The basic laboratory tests available
to evaluate post-travel illness include the following: |
| Complete blood count to screen for
anemia, eosinophilia, elevated white blood cell count and/or
low platelets |
| Thick and thin blood films to screen
for malaria (3 times over 24 hours) |
| Dip stick malaria assay, if available |
| Stool culture. Smear for fecal
leukocytes |
| Microscopic examination of stool for
ova and parasites |
| Liver function tests |
| HIV test. Suspect HIV when WBC count is
low, especially low total lymphocyte count. |
| Blood cultures |
| Serology testing (e.g., dengue, brucellosis,
typhus, amebiasis orl other parasites, etc.) |
| Chest x-ray, ultrasound, MRI |
| Urinalysis and urine culture |
It is only after a detailed history has been taken that a physical
examination should be performed and select laboratory tests obtained.

Important Alert
Malaria is the
most important illness to consider if you develop a fever after
having been in a malaria-endemic area, especially one in sub-Saharan
Africa or Oceania. If you develop a fever after returning home, be
sure to tell your doctor that you have traveled abroad and that a
tropical illness, especially malaria, is a possibility. If malaria
is a consideration, request thick and thin blood films and have them
repeated two to three times over 24 hours if the initial result is
negative. |
