Prior to going on any trips abroad, check the Centers for Disease Control and Prevention's web page or by calling 1-800-311-3435 to determine if there are any medical warnings for the country you are planning to visit. This site will also recommend any inoculations that may be needed before your trip. Check early as some vaccinations require a lead-time of months before a trip.

Obtain information on the country you are visiting at:

Centers for Disease Control and Prevention's Travelers' Health

and
