Traveling? Watch out for "tourista"

In 2008 and 2009 I travelled internationally and developed severe diarrhea and vomiting on the return trips to the United States. As a result of the 2008 trip, I spent a few days in the hospital. So, if you're doing any travel this summer (I'm definitely not), here are a few precautions (all of which I followed) from Harvard Men’s Health Watch, April 2010.

Traveler’s diarrhea, or “tourista,” is a well-known hazard for visitors to developing countries where sanitation is flawed. Here are some tips to prevent intestinal infections:

•Wash your hands with soap and water or an alcohol-based hand gel before you eat.
•Avoid salads, uncooked vegetables, and unpasteurized milk and cheese.
•Only eat fruit that you’ve washed in clean water and peeled yourself.
•Do not eat undercooked or rare food. Eat cooked foods while they
are still piping hot. Be especially wary of food from street vendors.
•Avoid the water unless you have boiled it yourself; chemical disinfectants
and water filters are available for use in special circumstances. Don’t use ice made from untreated water. Don’t use untreated water to brush your teeth. In general, unopened bottled or canned beverages are safe, as is coffee or tea made from boiled water.
•Ask your doctor about taking along antibiotics in case prevention fails.
•Above all, suspect everything.
