Medical advice for travelers should include evaluation of the risk for adverse outcomes depending on the traveler's medical conditions, the itinerary, anticipated activities, and potential exposures . Risks of illness associated with travel include:
●Development of illness while in transit 
●Exposure to infections endemic to areas visited
●Environmental exposures associated with travel
The pretravel evaluation should provide advice about the risks for vaccine-preventable infections, the appropriate immunizations, and prophylaxis against travelers' diarrhea and malaria . It should also include advice about behavioral precautions and environmental exposures.
