Medicines for your Vacation. Travelers should see a physician before leaving for a trip if they are going to developing countries, going off the usual tourist routes, or if they have chronic diseases that could be affected by travel. Travelers should protect themselves against common diseases that may be mild but that will disrupt their trip as well as protecting themselves against less common diseases that may be serious or even fatal. Some foreign countries require certain vaccinations before they will allow the traveler to enter the country. All travelers need to be up to date on routine vaccines they would normally get if they were not traveling (for example, an annual influenza vaccination if indicated).
Travelers to all inclusive resorts can pick up infections from contaminated food or water, from insect bites, animal bites, or from other people. Vaccinations, medications, and simple precautions can reduce or eliminate the risk of many of these travel-related infections.
Traveler's diarrhea is the most common medical complaint in travelers. It occurs when infectious organisms are ingested by travelers, resulting in one to five days of loose stools. The stools are often watery and may be accompanied by abdominal cramps. Up to half of travelers to developing countries will get traveler's diarrhea. Although not fatal, traveler's diarrhea can cause dehydration, vomiting, low-grade fever, and discomfort to the point that some travelers have to change their itinerary. It is important to note that traveler's diarrhea is not associated with bloody stools, severe abdominal pain, or high fever. These symptoms are suggestive of more serious conditions and should prompt medical attention.
Traveler's diarrhea is spread when bacteria or other infectious agents are ingested. It can be spread through contaminated food or water, or by putting contaminated hands in the mouth. Even small amounts of contamination can cause disease. Travelers can get diarrhea in most areas of the world, but some countries pose a higher risk. High risk areas include most of Asia, the Middle East, Africa, and Central and South America. Risk is increased if the traveler is adventurous with his or her diet, eats from street vendors, or travelers to areas off the usual tourist routes. Protective measures may help prevent or shorten the duration of traveler's diarrhea. All travelers should wash their hands often and understand basic food and water precautions. However, it has been shown that many people will still choose to eat foods that pose an increased risk of traveler's diarrhea. Therefore, travelers at risk should carry along an antimotility agent such as loperamide and start taking it if they get symptoms. Bismuth subsalicylate is also helpful. Many physicians also recommend that travelers carry along an antibiotic to take in case they get diarrhea. Fluoroquinolones, azithromycin, or rifaximin are those that are often used. Because organisms are developing resistance, many of the older antibiotics do not work well. If an antimotility agent and an antibiotic are started at the first sign of diarrhea, symptoms may be shortened to only a few hours instead of a few days. In rare cases, physicians might prescribe daily antibiotics or daily bismuth subsalicylate to prevent diarrhea, but this is not needed for most travelers. Affected people should stay hydrated. Pregnant women and children need special advice because many of these drugs are not appropriate for them. .
