Key Points:
The Risk of Illness While TravelingHow risky is foreign travel? People tend to exaggerate unlikely dangers such as terrorism or the potential for transmission of Ebola virus, and disregard or minimize more common perils such as 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 travelers 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 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:
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 preventive 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 events. Prevention of IllnessPreventing 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 IllnessesDiarrhea (see 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 and loperamide quickly resolves most cases of travelers’ diarrhea. Malaria (see 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. Check your itinerary carefully to assess your risk of exposure. Hepatitis (see 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. Figure

Countries
ACCIDENTS AND FATALITIES DURING TRAVELAlthough 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:
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. Table 1.1 Reported Deaths of U.S. Citizens Abroad by Cause of Death
*From October 1, 2002 to December 31, 2004 NOTE: This chart does not represent a statistically complete account of U.S. citizen deaths abroad. The chart depicts only deaths that were reported to the Department of State for which it was possible to establish that death was not due to natural causes. Most U.S. citizens who die abroad are resident abroad. Also, it is difficult to establish how many deaths go unreported to the Department of State. Note also that deaths attributed to "terrorist action" do not include deaths of U.S. military and government personnel in Iraq. 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 InjuriesIf you follow the recommendations below, you will decrease your chances of having an accident or being injured while driving overseas.

PERSONAL SAFETY GUIDELINESAlthough 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:
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). CORPORATE SECURITYRisk Management CompaniesIn times of geopolitical turmoil and terrorist activity, corporate interests are often targeted and advising corporations on matters of safety and security has become increasingly important. The companies listed below provide a variety of services that include the following: crisis management and contingency planning; hostage-release negotiation; counter-terrorism education/training; defensive driving training; executive protection; travel advisories and warnings; country-specific political analyses and risk assessments.

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
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.

Emergency Services to U.S. Citizens AbroadThe Office of American Citizens Services and Crisis Management (ACS) serves Americans traveling or residing abroad. Services provided by ACS include help with the following:
TRAVEL HEALTH INFORMATIONAlmost 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 CDCCDC'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. The book can also be purchased online (softcover) for $24.95 at http://www.amazon.com/ or at Elsevier Inc. at their website http://www.us.elsevierhealth.com/product.jsp?isbn=9780323048859.

The National Travel Health Network and Centre, NaTHNaC, was created to promote clinical standards in travel medicine by improving the quality of travel health advice available to GP practices and other health care providers. The Outbreak Surveillance reports are especially useful and much more comprehensive and up-to-date than those of WHO.
"fitfortravel" is a public access website provided by the NHS (Scotland). It gives travel health information for people travelling abroad from the UK. The website is compiled by a team of experts from the Travel Health division at Health Protection Scotland (HPS). This is the only site the Health Guide could find that has malaria maps of all endemic areas. Australia The Australian Government's travel advisory and consular assistance service. Europe
TRAVEL CLINICSBefore 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 ClinicIf 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. Travel Clinics in the United States & Canada
Finding Hospitals and Doctors OverseasThe 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 (see link below). 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. Travel insurance policies with assistance. Companies such as the International SOS (http://www.internationalsos.comand Medex (http://www.medexassist.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 DatabasesDuring 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.
