Cholera is a socioeconomic disease. It's a disease of malnourishment, poor health practices, slums and the poor, and it resides in those communities where these conditions are found. Travelers following the usual tourist itinerary and using standard accommodations in countries reporting cholera are at virtually no risk of infection. In fact, the risk of cholera to U.S. travelers (1 in 500,000 returning travelers) of any age is so low that it is questionable whether vaccination is of benefit. Our own Centers for Disease Control (CDC) in fact recommends against it. Always Be Foodwise and Waterwise to protect yourself from this disease. Currently no country or territory requires vaccination as a condition for entry, but some local authorities may continue to require documentation of vaccination against cholera or a letter from your physician stating that you have a contraindication to its use.
