The risk of becoming ill during travel depends on many factors including, but not limited to: region of the world visited, traveler's age and health status, immunization history, length of trip, and diversity of planned activities.
For people planning to travel out of the United States, particularly to developing countries such as Africa, Asia, and Latin America, it is important to talk to a physician who has expert knowledge of travel medicine as far in advance of your travel as possible.
Travel medicine physicians are up to date on international health regulations as well as which vaccines or medications would be needed in the preparation of your trip.
