Quite a few diseases, including hepatitis A and typhoid fever, are transmitted by unsanitary food handling procedures and contaminated water. Food and beverage precautions are essential in order to reduce chance of illness.

Hepatitis A vaccine is recommended for all travelers over one year of age. It should be given at least two weeks (preferably four weeks or more) before departure. A booster should be given 6-12 months later to confer long-term immunity.

Hepatitis B vaccine is recommended for travelers who will have intimate contact with local residents or potentially need blood transfusions or injections while abroad, especially if visiting for more than six months.
