Chikungunya Virus

Chikungunya is an illness spread by the bite of an infected mosquito. Chikungunya virus is transmitted in certain countries in Africa, Asia, Europe, the Indian and Pacific Oceans, the Caribbean, and the Americas. Cases in the U.S. are very rare and usually occur after travel to an area where chikungunya is common. Not all mosquito bites will make you sick, but it is still important to take steps to protect yourself and your family while traveling. Chikungunya is preventable. Please visit the Centers for Disease Control and Prevention (CDC) Travelers' Health page for more information on how to protect yourself from mosquito bites while traveling.
