Information for Travelers
Travel Health Insurance
As a traveler you must ensure that you are familiar with your health insurance coverage while
abroad. You must determine whether coverage applies to pre-existing medical conditions, to
conditions acquired during travel, to hospitalizations, or to medical evacuation from abroad. It is recommended that you contact your current insurance carrier for information and
documentation. You may wish to purchase travelers insurance to cover such conditions if
your current insurance plan does not meet your needs. For information regarding purchasing
travelers insurance you may visit the web si This web site also
provides information on acquiring passports, visas and special documentations for your destinations. Furthermore, you may search for local physicians for medical care at the
International Association for Medical Assistance to Travelers web si Again,
you must check with your insurance provider as to coverage and if any limitations apply.
Al travelers are encouraged to carry a travel kit which al ows you to have supplies and
medications readily accessible during your trip. The amount of supplies needed for such a kit wil depend on various factors such as travel expertise, location and conditions of destination,
duration of stay, pre-existing il nesses and availability of medical care if needed. Because
diarrhea and cold symptoms are the most common complaints during travel, it is advisable to
include items such as a thermometer, loperamide (Imodium), antacid, Bismuth subscalicylate
(Pepto Bismol tablets), analgesics (acetaminophen/non-steroidal anti-inflammatory), decongestants (psuedoephedrine), antihistamines (diphenhydramine), and cough
suppressant/expectorant. In addition, items such as sunscreen, antifungal cream, and
cortisone cream will be useful as skin problems are also common from insect bites, sun
exposure, and skin al ergens. Injuries although common are usual y minor such as blisters,
cuts, abrasions or bruises. Items to assist with the self treatment of these conditions include bandages and adhesives, scissors, splints, ace bandage, and duoderm or mole skin for blister
care. Another factor to consider when preparing your kit is the endemic diseases found in
the area of destination. Anti-malarial medication and insect repellent are a must to malaria
endemic areas. Visit the fol owing web sites for detailed information about recommendations for your destination,an
If you have pre-existing conditions you must ensure that usual medications are
sufficient for your trip and that your supply is adequate. If you have chronic medical
conditions you may notice exacerbation of your conditions while traveling. For instance, if
you have asthma you must ensure that you have a supply of a bronchodilator (Albuterol) in case of an exacerbation. If you suffer from severe al ergic reactions to certain foods or animal
bites you must carry an Epinephrine injection in case of anaphylaxis. In addition, if your
destination is to remote areas in developing countries where blood supply and medical
access are questionable you should consider carrying needles and syringes to ensure that
For most travelers purchasing a kit is less expensive then assembling one. More
information on travel kits is available at thweb site.
Note: Al travelers should carry original copies of their prescriptions if narcotics or injectable
medications are included. A written letter from the prescribing clinician which indicates the
medications and their purpose may also be utilized. Prescription medications and needles and syringes may be obtained through your travel clinician during your consultation.
In travelers the major cause of serious disability or loss of life is not infection. Trauma
caused by accidents, particularly automobile accidents, leads the list. Most vehicle accidents
are preventable or can be abated. In developing areas, roads are generally not as well
engineered as in developed areas, and road hazards are common. Defensive driving is the most important preventative measure. You should use safety belts when available. As a high
proportion of accidents occur at night when returning from “social events,” avoid non-
essential nighttime driving, alcohol, and driving with persons who are obviously under the
influence of alcohol or drugs. Pedestrian travel is sometimes risky in poorly regulated traffic,
Other major accidents include drowning, carbon monoxide poisoning, electric shocks,
and drug reactions from exposure to dangerous drugs. Protection against some potential y
hazardous drugs is nonexistent in some countries. Do not buy medications “over the
counter” unless you are familiar with the product.
Food and Water Precautions
Contaminated food and beverages are common sources for the introduction of infection into the body. Among the more common infections that travelers may acquire from
contaminated food and drinks are Escherichia coli (E. coli), shigellosis, bacil ary dysentery,
giardiasis, cryptosporidiosis, and hepatitis A. Other less common infectious disease risks for
travelers include typhoid fever and other salmonelloses, cholera, infections caused by
rotavirus and Norwalk-like viruses, and a variety of protozoan and helminth parasites (other than those that cause giardiasis and cryptosporidiosis). Many of the infectious diseases
transmitted in food and water can also be acquired directly through the fecal-oral route.
In areas where chlorinated tap water is not available, or where hygiene and sanitation are
poor, travelers should be advised that only the fol owing may be safe to drink:
Beverages, such as tea and coffee, made with boiling water.
Canned or bottled carbonated beverages, including carbonated, bottled soft
Beer and wine (in moderation), but not mixed alcoholic drinks.
Travelers should consider ice, and containers for drinking, contaminated if water itself may be
contaminated in that region. Thus, in these areas ice should not be used in beverages. If ice
has been in contact with containers used for drinking, the container should be thoroughly cleaned, preferably with soap and hot water, after the ice has been discarded.
It is safer to drink directly from a can or bottle than from a questionable container.
However, water on the outside of cans or bottles of beverages might be contaminated.
Therefore, wet cans or bottles should be dried before being opened, and surfaces which are contacted directly by the mouth in drinking should first be wiped clean. Where water may be
contaminated, travelers should avoid brushing their teeth with tap water.
Treatment of Water
Boiling is by far the most reliable method to make water of uncertain purity safe for drinking.
Water should be brought to a vigorous boil and al owed to cool to room temperature - do not
add ice. At very high altitudes, for an extra margin of safety, boil for several minutes or use
Chemical disinfection with iodine is an alternative method of water treatment when it
is not feasible to boil water. Two well-tested methods for disinfection with iodine are the use
of tincture of iodine, and the use of tetraglycine hydroperiodide tablets (Globaline, Potable
Agua, Coghlan’s, etc). The tablets are available from pharmacies, sporting good stores and/or
travel stores. The manufacturer’s instructions should be fol owed. There is a variety of
potable filters currently on the market which according to the manufacturers’ data wil provide safe drinking water. The CDC makes no recommendations regarding the use of any
As a last resort, if no source of safe dinking water is available or can be obtained, tap
water that is uncomfortably hot to touch is usual y safe. After al owing such hot water to cool
to room temperature in a thoroughly cleaned container, it may be used for brushing teeth, as well as drinking.
To avoid illness, food should be selected with care. Al raw food is subject to contamination.
Particularly in areas where hygiene and sanitation are inadequate, the traveler should be advised to avoid salads, uncooked vegetables, unpasteurized milk and milk products such as
cheese, and to eat only food that has been cooked and is stil hot, or fruit that has been
peeled by the traveler. Undercooked and raw meat, fish and shellfish may carry various
intestinal pathogens. Food and beverages from street vendors should be avoided.
Treatment of Travelers’ Diarrhea
Most cases of diarrhea are self limited and require only simple replacement of fluids
and salts lost in diarrhea stools or vomiting. Fluid and electrolyte balance can be maintained
by potable fruit juices, soft drinks (preferably caffeine-free), and salted crackers. Iced drinks
and noncarbonated bottled fluids made from water of uncertain quality should be avoided.
Dairy products aggravate diarrhea in some people and should be avoided. Travelers may prepare their own fruit juice from fresh fruit. Individuals with dehydration may require fluid
and electrolyte replacement in the form of oral re-hydration solutions (ORS) such as those
recommended by the World Health Organization (WHO). An ORS packet, available at stores
and pharmacies in almost al developing countries, should be added to boiled or treated
water, according to the packet instructions, and consumed or discarded within 12 hours if
held at room temperature, or 24 hours if held refrigerated.
Let your stools dictate your diet. If stools are watery, stick to a liquid diet. If stools are soft, eat
semi-solid foods. When stools return to normal, resume a regular diet.
When traveling to a developing country, consider carrying a thermometer, Loperamide
(Imodium AD - an over the counter anti-motility agent) and an antibiotic prescribed by your
clinician (e.g. Ciprofloxacin, Zithromax). In case of severe diarrhea (3 or more loose stools in
an 8 hour period or one loose stool accompanied by abdominal pain or blood), take your temperature:
If there is not an increase in your temperature, take the antibiotic and the
If you have a fever, take the antibiotic only. In case there is no prompt improvement, seek medical assistance.
(Loperamide is contraindicated in cases where fever accompanies travelers’ diarrhea. The
reason: fever may be due to organisms which are more likely to invade the intestinal lining.
Imodium slows intestinal motility. This may give the organism a better chance to invade the lining and prolong diarrhea).
Schistosomiasis is a parasitic infection found in travelers to Africa and occasional y Asia and
South America. It is found in contaminated fresh waters in these areas. Travelers are advised
to avoid swimming, bathing or wading in fresh bodies of water such as streams, ponds, rivers, lakes where this parasite may be found. Salt and chlorinated waters are thought to be free of
this parasite. Toweling oneself dry after unavoidable contact with these waters decreases the
risk of infection with this parasite. For more detailed information, visit the CDC website at
Leptospirosis is an infectious disease that is primary contracted through contact with contaminated soil or surface water in tropical areas. Activities such as kayaking, canoeing,
rafting, scuba diving, jungle trekking, and swimming in jungle rivers have been associated
with higher risk for this infection. Measures to minimize risk is to avoid potential y
contaminated soil and water and in some cases using an antibiotic as prophylaxis. Toweling
oneself dry after unavoidable contact with these waters decreases the risk of infection. Protective clothing and footwear should be worn and submersion in and drinking of surface
water should be avoided. For more detailed information, visit the CDC website at
Animals in general tend to avoid humans beings, but they can attack, particularly if they are
with their young. In areas of endemic rabies, domestic dogs, cats, or other animals should not
be petted or fed. Wild animals should be avoided. Rabies vaccine might be recommended in certain countries for long term travelers or certain occupations or activities (missionaries,
those en route with bikes, in those working with animals, or in those who explore caves). For
more detailed information, visit the CDC website at www.CDC.gov/travel/diseases.
Sexually Transmitted Diseases
International travelers are at risk of contracting sexual y transmitted infections (STIs) including human immunodeficiency virus (HIV, the cause of AIDS) if they choose sexual partners who
have these diseases. Travelers should be aware that the risk of STIs is high in some areas of
the world. AIDS has become a global health problem and the prevalence of HIV infection in
many populations continues to escalate. Also of concern are the antibiotic-resistant STI
agents, particularly penicillin-, tetracycline-and quinolone- resistant strains of Nesseria gonorrhea.
To avoid the risk of acquiring an STI, travelers should not have sexual contact with
persons who may be infected. Persons most likely to be infected are those with many sex
partners, such as prostitutes and others who have anonymous partners. In many areas,
persons who make themselves available for sex with travelers are likely to be persons with many partners. In addition, persons who use intravenous drugs are at high risk of being
infected with HIV, regardless of their number of sex partners.
Persons choosing to have sexual contact may reduce their risk of acquiring infections if
they avoid anal intercourse and ensure that a latex condom is always used during any genital
contact. Some unproven strategies for reducing the risk of STI transmission during sexual contact include: (1) using vaginal spermicides, (2) washing the genitals before and after
intercourse; and (3) mutual genital inspection prior to contemplated sexual contact with
avoidance of contact if signs of an STI are noted in either partner.
Persons with possible exposure to an STI should promptly seek competent medical
examination and treatment if they develop vaginal or urethral discharge, unexplained rash or genital lesion, or genital or pelvic pain. Since STIs are often asymptomatic, especial y in
women, persons with possible exposure should consult their clinician regarding the
Recommendation for prevention of HIV infection
HIV infection is preventable. HIV is transmitted through sexual intercourse, needle sharing, by
blood or blood components, and perinatal y from an infected mother. HIV is not transmitted
through casual contact; air, food, or water routes; contact with inanimate objects; or through
mosquitoes or other arthropod vectors. The use of any public conveyance (e.g., airplane, automobile, boat, bus, train) by persons with AIDS or HIV infection does not pose a risk of
• Have sexual intercourse (homosexual or heterosexual) with an infected person; • Use or al ow the use of contaminated, un-sterilized syringes or needles for any
injections or other skin-piercing procedures including acupuncture, use of illicit drugs,
steroid injections, medical/dental procedures, ear piercing, or tattooing;
• Use infected blood, blood components, or clotting factor concentrates. HIV infection
by this route is a rare occurrence in those countries or cities where donated
blood/plasma is screened for HIV antibody.
In less-developed nations, there may not be a formal program for testing blood or biological
products for antibody to HIV. In these countries, use of local y-produced blood clotting factor
concentrates should be avoided (when medical y prudent). If transfusion is necessary, the
blood should be tested if at al possible for HIV antibodies by appropriately trained laboratory
technicians using a reliable test. Needles used to draw blood or administer injections should be sterile, preferably of the single-use disposable type, and prepackaged in a sealed
container. Insulin-dependent diabetics or other persons who require routine or frequent
injections should carry a supply of syringes and needles sufficient to last their entire stay
A traveler who has had contact with blood or bodily fluids of another individual should
consider post-exposure prophylaxis (PEP) with antiretroviral medications. It should be started
as soon after exposure as possible and within 72 hours. Examples of high risk contacts
include travelers who are sexual y assaulted or health care workers with accidental needle
sticks. The travelers should receive medical evaluation as soon as possible and baseline blood testing (e.g. HIV, hepatitis C and B, Syphilis) should be done immediately, and repeated at 6
weeks, 12 weeks, and 6 months. Current guidelines recommend antiviral drugs be used for
at least 4 weeks after exposure. Discuss with your travel clinician current recommendations
for self administered antiretroviral medications in case high risk contact occurs. For example
a health care worker or volunteer providing care to HIV patients in rural areas may choose to obtain a prescription for an antiviral regimen in case a high risk contact occurs while carrying
for these patients. For further information and resources visit the www.aidsinfo.inh.gov web
Insect Borne illnesses
Personal protection measures/Avoiding mosquitoes and other anthropods • Avoidance is the main factor. Many insects are active at dusk and thus remaining
indoors at night is best. Stay in air-conditioned or well screened housing, and/or sleep
• Wearing long -sleeved shirts, socks, full length pants and a hat will protect most skin
• Tucking pant legs into socks or boots. • Apply insect repellent to exposed skin, clothing, mesh insect nets or shelters, window
screen, tents, or sleeping bags. This is the most effective and easiest way to protect
against bites. The CDC recommends repellent products that contain either 20-35%
DEET (N, N-diethyl-m-toluamide) or Picaridin (Bayrepel). They may be available in
lotion, towellet, gel, solid stick, and spray forms. Higher concentrations of active ingredient(s) provide longer duration of protection. Products with sustained release
or control ed release formulations may provide longer protection time. However,
concentrations above 50% do not confer more protection. Picaridin is odorless, not
greasy or oily. The 20 % Picaridin is as effective as DEET at the same concentration and
the 7% Picaridin is as effective as 10% DEET. Picaridin is less likely to cause skin irritation.
• Use a mosquito net over the bed if your bedroom is not air conditioned or screened.
For additional protection, treat the mosquito net with the insecticide permethrin.
• Spray an insecticide, permethrin (Permanone, Duranon), on clothing or to fabrics as
mosquitoes may bite through thin clothing. Do not apply to skin.
• Spray permethrin or a similar insecticide in your bedroom before going to bed. • If using sunscreen, apply sunscreen first and then repellent.
Note: Vitamin B and ultrasound devices do not prevent mosquito bites.
Malaria in humans is caused by one of four protozoan species of the genus Plasmodium: P.
falciparum, P. vivax, P. ovale, and P. malariae. Al are transmitted when an infected female
Anopheles mosquito bites and injects malaria parasites into humans. Occasionally transmission occurs by blood transfusion or congenital y from mother to baby. The disease is
characterized by fever and flu-like symptoms including chills, headaches, myalgias, and
malaise, which may occur at intervals. Malaria may be associated with anemia and jaundice,
and P. falciparum infections may cause kidney failure, coma, and death. Deaths due to
Information on malaria risk in specific countries is derived from various sources
including the World Health Organization (WHO) and the Center for Disease Control (CDC).
While this is the most accurate information available at the time of publication, factors which
can vary from year to year, such as local weather conditions, mosquito vector density and
prevalence of infection can have a marked effect on local malaria transmission patterns.
General advice for travelers to malaria-endemic areas
Al travelers to malarious areas of the world are advised to use appropriate drug regimen and
personal protection measures to prevent malaria; however, regardless of methods employed,
malaria may stil be contracted. Malaria symptoms can develop as early as 8 days after initial exposure in a malaria-endemic area and as late as several months after departure from a
malarious area, after chemoprophylaxis has been terminated. Travelers should understand
that malaria can be treated effectively in the course of the disease, but that delay of
appropriate therapy can have serious or even fatal consequences. Individuals who have
symptoms of malaria should seek prompt medical evaluation, including thick and thin blood smears, as soon as possible.
In choosing an appropriate chemoprophylaxis regimen before travel, persons should consider several factors. The travel itinerary should be reviewed in detail and compared with
the information on areas of risk within a given country to determine whether the traveler wil
actual y be at risk of acquiring malaria. It should also be determined whether the traveler wil
be at risk of acquiring chloroquine-resistant P. falciparum malaria. In addition, it should be
established whether the traveler has previously experienced an al ergic or other reaction to the antimalarial drug of choice and whether medical care will be readily accessible during
Malaria chemoprophylaxis should begin several days or weeks before travel to
malarious areas (depending on antimalaria medication used). In addition to assuring
adequate blood levels of the drug, this al ows any potential side effects to be evaluated and treated by the traveler’s clinician before departure. Chemoprophylaxis should continue
during travel in the malarious areas (and depending on the antimalaria medication) for days
to weeks after leaving the malarious areas.
In case of il ness
Symptoms of malaria may be mild, and you should suspect malaria if you experience
unexplained fever or other symptoms such as persistent headaches, muscular aching and
Malaria may be fatal if treatment is delayed. Medical help should be sought promptly
if malaria is suspected, and a blood sample should be taken and examined for malaria parasites on one or more occasions.
Self-treatment should be taken only if prompt medical care is not available. Medical
advice should still be sought as soon as possible after self-treatment.
Pregnant women and young children require attention because they cannot use some drugs
(e.g. doxycycline). Concurrent use of other drugs, e.g. beta-blockers, may be a

• Do not stop taking the tablets after arriving home; it is essential to complete the full
Trypanosomiasis/Tumbu fly larva infections.
Trypanosomiasis infection is transmitted via the tsetse fly found primarily in game parks of
East, Central and South Africa. It is also found in South America where it is called Chagas’
disease. Precautions include wearing long shirts and trousers, keeping vehicle windows rol ed up, by using insect repellents. Using bed netting permeated with insect spray when
sleeping in rural areas will also decrease transmission.
Tumbu fly larva infection occurs in tropical Africa. It occurs when the fly deposits eggs
on clothing or bathing suits dried outdoors. The larvae hatch and then penetrate the skin
when the garment comes in contact with the skin. It is prevented by ironing clothes dried outdoors.
Primarily found in urban areas Dengue fever or breakbone fever affects travelers to Southeast
Asia and Latin America and less frequently in Africa. It is transmitted via the Aedes aegypti
mosquito. Symptoms include fever, headache, body aches and at times a rash. The more
serious form of Dengue fever which is hemorrhagic fever occurs in people who are exposed with a second dengue infection. Preventative measures involve insect repellent/insecticide
