Key Points:

  • Health risks vary according to destination, itinerary, duration of journey, and medical history of the traveler.
  • Up to 65% of travelers to the developing world self-report a health problem during their trip. Most of these are mild, self-limited illnesses such as diarrhea, respiratory infections, and skin disorders.
  • About 8 percent of these travelers are sick enough to seek medical care either while traveling abroad or shortly after returning home.
  • Motor vehicle accidents and drownings are the most important cause of deaths in travelers younger than age 55; there is an increased incidence of injury-related death and drownings in Africa (2.7x) and SE Asia (1.6x) compared to the U.S.
  • Cardiovascular disease is the cause of most deaths in travelers >55 years of age.
  • Pre-departure planning, with assessment of potential disease risks, can help prevent illness or injury during your travel abroad.
  • Today, only 3 countries in the world have never stopped transmission of polio (Pakistan, Afghanistan and Nigeria) and vaccination may be required/recommended.

The Risk of Illness While Traveling

How risky is foreign travel? People tend to exaggerate dangers such as terrorism, or exotic diseases, such as Ebola virus, and disregard or minimize the more common perils of motor vehicle accidents and malaria. Disasters, like the Indonesian tsunami of December 2004, killed thousands of tourists, but such catastrophic events are infrequent and unpredictable. Large disasters often divert attention from the simple day-to-day precautions that you can take to stay healthy and safe.

The chances of acquiring certain diseases, or of having an accident, depend largely on where you travel and what you do while traveling. Out of over 30 million Americans who go abroad each year, approximately 8 million go to less developed countries where the incidences of tropical and infectious diseases are often high. Almost 7 million U.S. citizens travel to countries where there is risk of malaria. Surveys of travelers show that:

  • There is a 60% to 70% possibility of illness when traveling in less developed countries for up to 90 days (median trip duration—19 days). Most of these illnesses are minor.
  • There is a 5% to 8% chance you will seek medical care while traveling in a developing country.
  • Your chance of being hospitalized will be less than 1%.
  • The most common reported illnesses are: diarrhea (34%); a respiratory disease (26%); a skin disorder (8%); acute mountain sickness (6%); motion sickness (5%); an accident and injury (5%); an illness with fever (3%).
  • On return home, there is about a 25% chance that you will have a bout of diarrhea, a respiratory illness, a skin problem, or a fever related to your trip.

Your individual risk, however, may vary considerably. For example, if visiting the Indian subcontinent, (and particularly friends and relatives) your risk of typhoid fever may be 18 times greater than for any other geographic region. Other variables that can affect your health include (1) the duration of your trip; (2) your use (or nonuse) of antimalarial drugs; (3) your use of prevention measures against insect bites; (4) your vaccination status; (5) your risk-taking (or avoidance) behavior; and (6) your underlying health status.

Bear in mind, though, that traveling is usually good for one’s physical and emotional health. Aside from seeking holiday pleasures, some people travel to improve their lifestyle, perhaps to change harmful personal habits, “get in shape”—or temporarily (perhaps permanently) leave a stressful job, a bad relationship, a harsh climate, or other adverse life situation.

Prevention of Illness

Preventing illness abroad involves learning as much as possible about the countries you will be visiting, consulting with a travel medicine provider to receive immunizations and medications and taking the necessary clothing, equipment, or devices (such as a water filter or mosquito net) to deal with local health conditions and climate. Your own health status should also be evaluated.

Most travel-related diseases can be prevented. Hepatitis, meningitis, yellow fever, and rabies are some of the many diseases that can be prevented by vaccination. Chemoprophylaxis, combined with protective measures against mosquito bites, can prevent virtually all cases of malaria, as well as many other insect-transmitted diseases, such as dengue fever and Japanese encephalitis. Sexually transmitted diseases, including HIV, can be avoided with behavior modification.

Types of Illnesses

Diarrhea (Chapter 6) This is the most common malady affecting travelers. There is a 35% to 60% chance that you will acquire travelers’ diarrhea during a month-long trip to a less-developed country. Adhering to safe food and drink practices can reduce your risk (but most travelers have trouble sticking to the guidelines). Prompt treatment with antibiotics (Azithromycin or Ciprofloxacin) and loperamide quickly controls most cases of travelers’ diarrhea.

Malaria (Chapter 7) This mosquito-transmitted illness, which can be fatal, is the most important parasitic disease to avoid overseas. Malaria is a serious health problem in many tropical and subtropical countries, especially sub-Saharan Africa. Check your itinerary carefully to assess your risk of exposure.

Hepatitis (Chapter 12) The viruses hepatitis A and hepatitis B pose potential risks for some travelers. Although both are rarely fatal, hepatitis A can ruin a carefully planned vacation and result in weeks or months of disability; contracting hepatitis B can have serious long-term consequences, including cirrhosis of the liver and liver cancer. You can prevent both hepatitis A and hepatitis B with vaccination. Although there are no vaccines against hepatitis C and E, Chapter 12 outlines measures you can take to reduce your risk of these illnesses.

Other Illnesses Colds and respiratory infections, skin rashes, ear infections, sunburn, sprains, contusions, and superficial injuries account for the majority of less serious problems.


Although it is quite possible you will have some type of minor illness while abroad, the chance that your illness will be fatal is reassuringly small. Approximately 6,000 Americans die outside of the U.S. each year. The majority of these are long-term residents of a foreign country. The U. S. Department of State assists with the return of remains for approximately 2,000 Americans annually. Mortality abroad is due mainly to heart attacks, motor vehicle accidents, drownings, and other injuries. Cardiovascular disease causes about 50% of all deaths abroad, but most of these occur in older travelers. Cardiovascular death rates are not significantly increased by travel. Other points include the following:

  • Injuries are the most common cause of death in younger travelers. Fatal injuries are mostly due to motor vehicle accidents and drownings. Air crashes (usually nonscheduled carries), suicides/homicides, burns, and electrocution are less frequent causes.
  • The number of accidental deaths in 15- to 44-year-old travelers is higher by a factor of 2 to 3 as compared with rates among the same age group back at home in the United States or Canada. “Excess mortality” abroad, therefore, is mainly due to accidental injuries—not cardiovascular disease.
  • Infections cause fewer than 4% of deaths abroad.

Accidents are the leading cause of death among travelers younger than the age of 55. Death rates from motor vehicle accidents, according to The Association for Safe International Road Travel, are 20 to 80 times higher in some countries than in the United States, illustrating one reason why “excess mortality” abroad is primarily injury related.

Studies have revealed that many road accidents involving tourists do not involve a collision between two vehicles but are due to loss of driver control caused by fatigue, alcohol or drug intoxication, unfamiliar road conditions, or other factors. In addition, in most developing countries vehicles are often in disrepair; roads poorly maintained; and common-sense rules of the road disregarded.

The Bethesda, Maryland-based Association for Safe International Road Travel (ASIRT; Tel: 301-983-5252; website: www.asirt.org) can provide a report on road safety conditions in 70 foreign countries. Their road travel reports also contain information about seasonal hazards; city, rural, and interstate traffic; and the most dangerous roads in various countries. ASIRT currently cites Egypt, Kenya, India, South Korea, Turkey, and Morocco as some of the most dangerous countries. (ASIRT, a nonprofit organization, requests a small donation in exchange for the information it provides.)

Preventing Traffic Accidents and Injuries

If you follow the recommendations below, you will decrease your chances of having an accident or being injured while driving overseas.

  • Always wear a seat belt. Do not rent a vehicle without seat belts.
  • Bring a car seat for infants, and place them in the back seat.
  • Consider hiring a qualified guide or driver. This is essential in many countries, e.g., India.
  • Do not be afraid to tell your driver to slow down or use more caution.
  • Rent a larger rather than a smaller vehicle.
  • Know the meaning of all international road sign symbols.
  • Note that in some countries road signs are almost totally lacking—or the signs may be in the local language.
  • Be sure you have collision/liability insurance.
  • Know that a driver approaching a traffic circle must yield the right of way to those already in the circle.
  • This traffic rule, like many others, may not be followed. Many drivers overseas just “drive with their horn.”
  • Know the route to your destination. Study road maps (if available) thoroughly in advance of your trip.

Other advice for improving your road safety:

  • Drive defensively.
  • Keep a well-stocked first aid kit in your car and know how to use it.
  • Travel in convoy with other cars.
  • Do not travel alone in a vehicle.
  • Have a communications system that covers where you are traveling.
  • Report your progress to someone who knows your route plan and agree with them what action they will take if you do not make contact at a scheduled time.
  • Plan how you will get emergency service in response to an accident.
  • Plan how you will get medical treatment in case of an accident.

The two most important rules to follow are:

  • Do not drive at night in rural areas.
  • Do not ride a motorcycle, moped, or bicycle (even if you are experienced).


Although you can’t escape the remote possibility that you simply may find yourself “in the wrong place at the wrong time,” you can take steps to enhance your personal safety while traveling: plan your trip carefully, be reasonably cautious, obey common-sense rules of behavior, and don’t panic! Remember that the vast majority of travelers arrive home unscathed.

The following guidelines will be helpful in ensuring your travel safety:

  • Carefully select swimming areas. Don’t swim alone, while intoxicated, or at night.
  • Avoid small, nonscheduled airlines in less developed countries.
  • Don’t travel by road at night outside urban areas. If you are out at night, stay in a group.
  • Don’t go out alone on beaches at night.
  • Don’t hitchhike or pick up hitchhikers.
  • Don’t sleep in your car or RV at the roadside at night.
  • Camp only in legal campsites.
  • If you are drinking alcohol, don’t relax by sitting on the railing of your hotel balcony. Falls and serious injuries often occur this way.
  • Review hotel fire safety rules. Locate nearest exits.
  • If possible, book a room between the second and seventh floors—high enough to prevent easy entrance by an intruder and low enough for fire equipment to reach.
  • Lock your hotel room at all times.
  • Keep valuables and travel documents in your room (in-room safe) or hotel safe.
  • Avoid countries or regions where there is drug-related violence and drug trafficking. Avoid excursions into remote areas of certain countries such as Mexico, Colombia, or Peru, where you might be mistaken for a drug agent or a rival drug dealer.
  • Never purchase, transport, or use illegal drugs.
  • Don’t accept drinks or rides from a stranger you have just met.
  • Familiarize yourself with the local laws and customs of the countries to which you are traveling and abide by them. Know the laws about exchanging money and deal only with authorized agents when you exchange money or purchase art or antiques.
  • Put identifying markings on your luggage. Don’t, however, put your home address or telephone number on your luggage tags. Instead, put a business card in the tag, or a use a P.O. box address and a business, mobile telephone, or third- party telephone number for contact.
  • Do not put all your valuables in luggage you check; e.g., jewelry, cameras, watches. Besides your luggage possibly being lost, there is, unfortunately, increasing theft occurring during security searches of checked luggage. The best course is not to travel with any item of significant value.

There are numerous publications that provide specific advice on personal safety and security. Suggested titles include The Safe Travel Book—A Guide for the International Traveler by Peter Savage (Lexington Books: 800-462-6420) and The Security Minute; How to Be Safe in the Streets, at Home, and Abroad So You Can Save Your Life! by Robert L. Siciliano (Safety Zone Press: 800-438-6223).

State Department Security Advisories

You can obtain in-depth advice about specific security issues in any country by contacting the Regional Security Officer (RSO) at the embassy of the country to which you will be traveling. Here is the procedure:

  • Contact the Department of State at 202-647-4000 and ask to be connected to the Country Desk covering the destination country.
  • Request the name and overseas telephone number of the Regional Security Officer (RSO) stationed at the embassy. The State Department maintains a listing of these Key Officers at each embassy.
  • Telephone the RSO during embassy business hours in the destination country. Inquiries often include questions about:
  • The safest taxi cab/route to take from the airport
  • Street crime or terrorism problems
  • Neighborhoods to avoid
  • Recent incidents involving tourists or corporate executives
  • Safety of public transportation


The Overseas Security Advisory Council (OSAC) was established in 1985 by the U.S. Department of State to foster the exchange of security-related information between the U.S. Government and American private sector operating abroad. Administered by the Bureau of Diplomatic Security, OSAC has developed into a successful joint venture for effective security cooperation. Through OSAC, the American private sector, including colleges and universities, is provided timely information on which to make informed corporate decisions on how best to protect their investment, facilities, and personnel abroad.


How the U.S. Government Can Help

The website of the Bureau of Consular Affairs (www.travel.state.gov) is an extensive and convenient source of information that lists passport and visa requirements, foreign country entry requirements, a listing of embassies and consulates overseas, and emergency services for U.S. citizens abroad. The Bureau of Consular Affairs Office of American Citizens Services and Crisis Management (a division within the Bureau of Consular Affairs) issues consular information sheets, travel advisories/warnings, and public announcements on more than 200 countries.

  • Consular information sheets include the location and telephone number of the embassy and each consulate, information on health conditions, political disturbances, currency, entry regulations, and crime and security activities in each country.
  • Public announcements disseminate information about terrorist threats and other relatively short-term and/or trans-national conditions posing significant risks to the security of travelers.
  • Travel warnings list countries the State Department believes should be avoided, except for essential travel. Some travel authorities believe, believe, however, that the travel warnings are often alarmist and damage tourism to a particular country.

Emergency Services to U.S. Citizens Abroad

The Office of American Citizens Services and Crisis Management (ACS) serves Americans traveling or residing abroad. The ACS corresponds organizationally to American Citizens Services offices set up at U.S. embassies and consulates throughout the world. ACS has five geographical divisions with case officers who assist in all matters involving protective services for Americans abroad, including arrests, death cases, financial or medical emergencies, and welfare and whereabouts inquiries. The office also issues Travel Warnings, Travel Alerts and Country Specific Information (see above) and provides guidance on nationality and citizenship determination, document issuance, judicial and notarial services, estates and property claims, third-country representation, and disaster assistance. Services provided by ACS include help with the following:

  • Arrest/detention of an American citizen abroad
  • Robbery of a citizen abroad
  • Death of an American citizen abroad
  • American citizen missing abroad; welfare and whereabouts inquiries
  • Legal services; document issuance; help with financial emergencies
  • Disaster assistance
  • Crises abroad that involve a U.S. citizen
  • Medical emergencies. If emergency medical transport or an air ambulance is needed, the OCS may refer you (or the people helping you) to an assistance company. The U.S. government won’t pay the costs of transport, but the OCS can facilitate transfer of funds. Working with the embassy or consulate, the OCS will help coordinate stretcher transport on a commercial airliner to bring a sick traveler home to the United States. In event of death, they will assist with returning the remains.
  • Contacting the Office of Overseas Citizens Services directly Consular duty personnel are available for emergency assistance 24 hours a day, 7 days a week, at embassies, consulates, and consular agencies overseas and in Washington, D.C. To contact the Office of Overseas Citizens Services in the U.S. call 1-888-407-4747 (during business hours) or 202-647-5225 (after hours). Contact information for U.S. embassies, consulates, and consular agencies overseas is on the Internet site. Overseas Citizens Services Telephone Assistance—888-407-4747 (From Canada and overseas: 202-501-4444).

How Foreign Government Agencies Can Help

The Canadian, British, and Australian governments provide extensive information resources for the traveler. These updated reports focus on travel advice by country, safety and security, entry requirements, health issues, travel insurance, and more. The Foreign and Commonwealth Office (FCO) in the UK is one of the best organized and concise – they even have a LOCATE service that provides emergency advice to UK nationals who register with them. The Australian Government’s Smartraveler is another excellent resource. Canadian travel information is contained on two websites, Foreign Affairs Canada and Public Health Agency of Canada.


Almost all health problems related to travel are either preventable or can be minimized, but most travelers are often unaware of just what those risks may be. A travel clinic can be an excellent source for this information, but time constraints limit the amount of advice a practitioner can dispense in one or two office visits. And if the clinic hands out printed material, how much will you read or remember? And is the information you are given sufficient? It is often essential that you do additional pre-departure reading and data gathering. The Internet can provide the most current information, if you know where to find it, but books that are updated on a regular basis are also good references (and can be brought along on your trip, as well). However, it’s possible that no single resource, printed or electronic, will provide all the information that you may need, so numerous resources are listed in this chapter. Be aware that these sources of information may not always be in agreement. For example, the Centers for Disease Control and Prevention (CDC) recommends that malaria prophylaxis be taken in all malarious areas, whereas many travel clinics and other information sources usually advise that low-risk, short-term travelers may rely instead on insect bite-prevention measures, or carry standby malaria treatment medication. And some literature in travel medicine advises that children with diarrhea not be treated with quinolone antibiotics, when in fact this treatment may be preferred. NOTE: Information is sometimes available from retail travel agents, tour operators, and airlines and other common carriers, but the quality of this information varies and may be unreliable.

Travel Health Information from the CDC

CDC’s Traveler’s Health website – http://wwwn.cdc.gov/travel

Go to the website of the Centers for Disease Control and Prevention (CDC) to obtain a vast amount of travel health advice and information, such as disease outbreaks, vaccination requirements, destination risks, and much more. You can also download for free chapters from Health Information for International Travel (the Yellow Book. The Yellow Book is published every two years by the CDC as a reference for those who advise international travelers of health risks, but it is also useful for travelers who are not medical professionals.

Europe and worldwide


Before you depart you’ll want to consult with your health-care provider if you have medical problems, are traveling to a less-developed country (where there is often the risk of tropical and infectious diseases), or planning an extended trip abroad. Specialized immunizations and prophylactic medications may be recommended or required. Although your own doctor may be able to administer some routine immunizations, most physicians’ offices don’t stock specialized vaccines, such as typhoid, rabies, or meningitis, and they are not authorized to stock and administer yellow fever vaccine, or issue the International Certificate of Vaccination. (Public health departments can administer yellow fever vaccines.) More importantly, your health-care provider may not have the expertise or resources to advise you about safe travel, or what to do if you get sick abroad. There are more than 220 different countries with evolving and varying disease-risk patterns, and providing travelers with accurate health information can be complex and time consuming. Most physicians are not prepared, or willing, to give this type of consultation.

Fortunately, the specialty of travel medicine has expanded rapidly over the past 15 years and there are now many physicians and nurse practitioners that either specialize in this field, or have added it to their regular practice. Although no specialty board certification is required to practice travel medicine, most travel medicine practitioners have received further training under the auspices of the International Society of Travel Medicine (www.istm.org) and/or the American Society of Tropical Medicine and Hygiene (www.astmh.org). Both of these organizations have developed specialty examinations that award a Certificate of Knowledge.

More information on the practice of travel medicine is found here.

Types of Travel Clinics Travel clinics vary in their ranges of services and professional staffing. Sometimes a medical facility is dedicated solely to this specialty, but often a travel clinic is from a doctor’s private practice, an ambulatory care clinic, an HMO or group practice, an occupational health clinic, or the infectious disease department of a university teaching hospital. These clinics, unlike regular physician’s offices, are almost all tied into Internet and electronic databases that provide them with updated travel/health information and conditions worldwide.

Travel clinics supervised by physicians trained in infectious and/or tropical diseases are usually better able to counsel travelers with special needs, or who have returned from abroad with a suspected or undiagnosed tropical or infectious disease. Such clinics are often, but not invariably, associated with a university hospital or a medical school.

Finding a Travel Clinic

If you need to locate a travel clinic, visit one of the websites listed below. They have extensive listings, but no one website lists all clinics currently operational. The ISTM, ASTM&H, and Travel Medicine, Inc., websites also list travel clinics in many countries worldwide. This can be helpful if a travel/tropical disease specialist needs to be contacted for an illness occurring abroad.

Finding Hospitals and Doctors Overseas

The International Association for Medical Assistance to Travellers (IAMAT) publishes a booklet listing English-speaking physicians and healthcare facilities worldwide. IAMAT also provides information on tropical diseases such as malaria and schistosomiasis. IAMAT is a tax-free foundation, and there is no charge for their publications; a donation, however, is requested. IAMAT, 417 Center Street, Lewiston, NY 14092; 716-754brr4883. In Canada: 40 Regal Road, Guelph, Ontario, N1K 1B5; 519-836-0102.

The Destinations section on www.travmed.com has listings of hospitals and physicians for every country.

Chapter 16 of this book will tell you how to locate medical care abroad.

Hotels and resorts can refer you to a local English-speaking doctor.

Most U.S. and Canadian embassies and consulates maintain lists of physicians and medical facilities for distribution to travelers needing medical care. The inclusion of a specific physician or medical facility does not constitute a recommendation and the Department of State assumes no responsibility or liability for the professional ability or reputation of, or the quality of services provided by, the medical professionals, medical facilities, or air ambulance services whose names appear on such lists. See U.S. Embassies and Consulates websites to access medical lists for specific countries. Lists are normally found under the American. Citizens Services section of the embassy website. Note: These lists are not always well-maintained or updated. The U.S. Department of State has not established a standard form or protocol for identifying medical in each country. https://www.uhcsafetrip.com

Travel insurance policies with assistance. Companies such as the International SOS (http://www.internationalsos) and UnitedHealthcare (http://www.uhcsafetrip.com) provide policyholders with access to an extensive network of doctors and hospitals worldwide. Physician referrals and monitoring of hospital care are parts of the assistance package provided.

Obviously, in many emergencies, such as a heart attack, stroke, or serious motor vehicle accident, you won’t be able to choose which facility you’re transported to. (And in many locations there won’t be alternative choices.) This is why travel medical insurance that has an “assistance” feature is so important; the assistance hotline center can monitor your medical care and decide if immediate evacuation to a more advanced medical facility, even in another country, is indicated.

Travel Medicine Databases

During the past decade, there have been dramatic increases in the amount of travel health information available electronically, either via the Internet or distributed on PC disks or CD-ROMs. The advantage of these systems lies in their ability to provide updated, organized, itinerary-specific information in a format that can be printed out for the traveler. This is of great help in pre-travel counseling and trip preparation. In addition, some systems can also alert overseas travelers via e-mail about evolving emergency conditions—be they medical or safety/security related. Other systems allow a company to check on an employee’s whereabouts and current status—a feature especially used by corporate medical and security departments tracking overseas employees who may be at risk.

TRAVEL CARE—International SOS Assistance, Inc., 3600 Horizon Boulevard, Suite 300, Trevose, PA 19053; 215-942-8000 or 1-800-523-8930. Website: www.internationalsos.com or www.internationalsos.com/demo/travel_care for a free demonstration.

Online travel health program designed for the medical professional conducting pre-travel medical consultations. TRAVEL CARE’s sophisticated but easy-to-use databases help the practitioner decide on appropriate vaccinations and malaria prophylaxis and also evaluate current health risks for any itinerary.
