All travelers should familiarize themselves with conditions at their destination that could affect their health (high altitude or pollution, types of medical facilities, required immunizations, availability of required pharmaceuticals, etc.).
While some of this information may be found in the documents listed above, the key resource for health information is the Travelers’ Health page of the Centers for Disease Control (CDC) website at http://www.cdc.gov/travel.
The CDC website also provides general guidance on health precautions, such as safe food and water precautions and insect-bite protection. The CDC also maintains an international travelers’ hotline at 1-877-FYI-TRIP (1-877-394-8747).
