Dengue and Dengue Hemorrhagic Fever: Spread by mosquitoes, dengue viruses infect up to 100 million people annually. Puerto Rico experienced its largest outbreak in 2010 and Florida has reported local cases for the first time in 75 years. DVBD is working to advance diagnostics, improve patient survival, find new methods of mosquito control and develop innovative vaccines. Read CDC’s Dengue Update for more.
Lyme and other tick-borne diseases: Tick-borne diseases, including Lyme disease and Rocky Mountain spotted fever are serious public health problems, infecting tens of thousands in the U.S. each year. CDC is working closely with local communities, developing innovative control approaches and researching improved diagnostics.
West Nile and other mosquito-borne viruses: West Nile virus swept across the U.S. in less than 10 years, causing over 12,700 cases of severe disease. CDC leads ArboNET, an innovative system to monitor mosquito-borne infections in humans, mosquitoes, birds and other animals. This information allows CDC and states to quickly respond, preventing further cases. CDC and its partners implemented screening of the U.S. blood supply for WNV, preventing 3,000-9,000 transfusion-transmitted infections.
Innovation: DVBD scientists have developed innovative candidate vaccines against dengue and West Nile viruses, including the first DNA vaccine ever to be licensed. We are collaborating with industry to bring to market novel insecticides derived from natural products, and are developing new tools to reduce ticks and mosquitoes that spread disease.
Responding to new and old threats: DVBD scientists are working to reduce the impact of plague, an ancient disease, in the U.S. and in Uganda. On the other hand, we are preparing for emerging epidemics, like chikungunya virus, which spread rapidly throughout the Indian Ocean to Europe. On average, 2 new mosquito-transmitted viruses infective to humans are found each year.
