Data Source For Areas Affected

The maps designate countries considered to be affected by a disease. Areas within countries may or may not be affected by a specific disease. Consult with a Travel Healthcare Provider or www.cdc.gov/travel about your specific itinerary prior to travel. Reporting activity data are provided by Sitata and derived from numerous sources, including official surveillance data and news reports. Reporting activity does not reflect current risk of infection with a disease. Not all areas report cases of disease; therefore, the absence of activity on the map does not indicate that a disease is not present. The relationship between the intensity of reporting activity and actual disease transmission is unknown and does not indicate a difference in risk. Maps do not reflect differential distribution of diseases within a country.

Travel health tips

Resist petting dogs during your travels! Rabies is spread by saliva, so even a friendly lick can be dangerous

Lots of us are “dog” people and can’t resist petting an adorable pup during our travels. But if you don’t know it, don’t pet it! Rabies is spread by saliva, so even a friendly lick can be dangerous. Take a picture of it instead.

Be cautious of a fresh fish catch! Certain areas have a higher risk of toxins that cause Ciguatera, a type of food poisoning

There’s nothing like the taste of a fresh catch, but certain fish (like red snapper, sea bass, and sturgeon) found in the Caribbean Sea and the Pacific and Indian Oceans have a higher risk of toxins that can cause Ciguatera (sig-wah-TARE-ah), a type of food poisoning. Consider catch and release when fishing in those areas!

Lower your risk of catching an infectious disease by using mosquito repellent and wearing long sleeves and pants

Mosquitos can spread serious, even fatal infectious diseases. To lower your risk of catching one of these diseases, remember to use mosquito repellent on bare skin, and wear long pants and long-sleeved shirts, socks, and shoes. And, to help turn off mosquitos, turn on the air conditioning.

Beware of fruity drinks while traveling! Go for canned or bottled to lower the risk of diarrhea and other diseases

Fruity drinks may hit the spot when you’re at a tropical location but go for the canned or bottled kind. Local tap or well water (or ice made from either), along with fruit washed with the same local water, can put you at risk for traveler’s diarrhea and other diseases.
