General Information

Contact your health care provider at least 6 weeks before departure for current health information on the country you plan to visit and to obtain vaccinations and medications as needed.

The risk of becoming ill during international travel depends on the regions of the world visited, the types of destinations within a country, season of travel, individual factors, and diligence in use of protective measures.

~Wash hands often with soap and water, or use an alcohol-based hand gel.
~Drink only bottled or boiled water, or carbonated (bubbly) drinks in cans or bottles.
~Avoid tap water, fountain drinks, and ice cubes.
~Eat only thoroughly cooked food or fruits and vegetables you have peeled yourself.
~Avoid purchasing food from street vendors. Remember: boil it, cook it, peel it, or forget it.
~Protect yourself from mosquitoes, especially between dusk and dawn by wearing
long-sleeved shirts, long pants, and hats. Use insect repellents that contain DEET Picaridin, or Oil of Lemon Eucalyptus following the directions and precautions on the product label. Please read Mosquito Bite Prevention for Travelers.
~Walk and drive defensively. Avoid walking barefoot.
~Don’t swim in fresh water. Salt water is usually safer.
