About the Division of Vector-Borne Diseases

The Division of Vector-Borne Diseases (DVBD) strives to protect the nation from bacterial and viral diseases transmitted by mosquitoes, ticks and fleas. Some of these diseases have long been present in the United States while others have recently emerged. These include some of the world's most destructive diseases, many of which are increasing threats to human health as the environment changes and globalization increases. CDC/DVBD plays a unique role, housing much of the world’s expertise in the diagnosis, prevention and control of these diseases.


Chikungunya virus spreading in the Americas

Chikungunya is a viral disease spread to people by the bite of infected mosquitoes. The most common symptoms of chikungunya virus infection are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. This virus was found for the first time in late 2013 among non-travelers in the Western Hemisphere. Local transmission has been identified in Caribbean countries and territories or South America. Chikungunya will likely continue spreading to new areas (North America, Central America, and South America). For updated data on suspected and laboratory-confirmed cases from these areas, visit the PAHO (Pan American Health Organization) website.
