Chikungunya Fever-An Emerging Mosquito Virus of Concern

As you prepare for the July 4th holiday, remember to protect yourself and your family from mosquito-borne diseases. Outbreaks of Chikungunya fever were first reported in Tanzania in 1952. Chikungunya fever is a virus and two mosquito species commonly found in Florida- the yellow fever mosquito, Aedes aegypti, and the Asian tiger mosquito, Aedes albopictus, are potential vectors. Increasingly, individuals who have traveled to Caribbean and Latin American countries have returned to the U.S. with imported cases of Chikungunya fever. Over time, the potential for locally acquired cases of Chikungunya exists due to the distribution of the mosquito vectors within Florida. Symptoms of the disease may include a high fever, rash, muscle pain, and joint pain within two weeks of a mosquito bite. Additionally, it is possible for a mosquito to transmit both Chikungunya fever and Dengue fever to a person. The Florida Department of Health continues to protect the citizens of Florida through weekly mosquito surveillance and disease reports. Weekly reports are available at: Image of the Florida Department of Health Chikungunya website.

During 2014, travel related cases of Chikungunya (48) and Dengue (24) have occurred in Florida.

How can you prevent exposure to Chikungunya or Dengue? Use EPA approved mosquito repellants, such as those containing DEET, reduce standing water in your yard (a habitat for immature larval mosquitoes), and avoid the outdoors during dawn and dusk. It is also important for homes to have screens and windows that will prevent entry of mosquitoes into the home.
