Immunizations, medications, and common sense for the international traveler.

Health advice for international travelers should be individualized, taking into account the itinerary, the lifestyle of the traveler, the duration of travel, the patient's medical history, and other modifying factors. Although patients often seek advice because of immunization requirements, the pretravel visit should consider additional indicated immunizations; health maintenance advice regarding food, drink, and activities; malaria prevention when indicated; and diarrhea management. The traveler should be advised about a basic medical kit and receive information as to where to seek medical advice should serious illness develop while travelling.
