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 Hits U.S. Mainland

The first locally acquired cases of chikungunya were reported in Florida on July 17, 2014. These cases represent the first time that mosquitoes in the continental United States are thought to have spread the virus to non-travelers. Though CDC does not expect widespread cases this year, Americans infected when traveling to the Caribbean, South America, or the Pacific Islands may continue to return and bring the virus with them. For updates on locally acquired and travel associated chikungunya cases, visit CDC’s chikungunya website.

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.

What is Bourbon Virus?

a newly discovered thogotovirus

In 2014, CDC discovered a new virus in a sample from a previously healthy man from eastern Kansas. He became unwell with fever and other symptoms in the late spring. Bourbon virus, named after the county in Kansas where this man lived, is part of a group of viruses (thogotoviruses) known to be spread through ticks and other vectors.

CDC scientist will be working with state partners to understand more about this novel virus. Studies are planned and ongoing to determine who gets infected, how they are infected, where this virus is located, and how this virus is making people sick.
