Mosquito-borne Viral Diseases

Several mosquito-borne viruses circulate in Georgia each year and are capable of causing disease in humans and other animals. The most common mosquito-borne viruses in Georgia include West Nile virus, Eastern Equine encephalitis virus, and LaCrosse virus. Saint Louis encephalitis virus has also been detected in Georgia in the past. Mosquito-borne viruses are most active late spring through early fall in Georgia.
 

Information for the Public

Mosquito-borne viruses can infect birds, horses, and other animals in addition to humans. If public health reports positive birds or horses in your area, or if you see large numbers of mosquitoes, you could be at increased risk of infection. Always take personal protective measures to avoid mosquito bites, especially when mosquito-borne viruses have been identified near you.

Information for Healthcare Providers and Laboratories

Testing for West Nile Virus – Forms and Instructions:
Commercial tests to detect WNv and other arbovirus antibodies are readily available at most commercial laboratories. During 2009, GDPH recommends that diagnostic testing for human arbovirus infections be performed at commercial laboratories. The Georgia Public Health Laboratory (GPHL) can perform testing for serologic evidence of infection with each of the arboviruses that circulate in Georgia, but due to limited resources, specimens will not be tested by GPHL unless they meet the testing criteria. Please call the Georgia Department of Public Health (404-657-2588) or the appropriate District Health Office before submitting specimens for arboviral testing to assure that the criteria are met for testing at GPHL and all necessary forms are completed. If needed, specimens with positive results for WNv or other arboviruses at commercial laboratories can be confirmed at GPHL. Please do not submit specimens unless testing criteria are met; ineligible specimens will not be tested.

Dead bird and mosquito testing is no longer provided free of charge through the Southeastern Cooperative Wildlife Disease Study at University of Georgia in Athens, although a few counties are still doing some limited testing either through Environmental Health or through mosquito control.

Mosquito Control

Be an Educated Consumer!
From University of Florida: There are many devices on the market advertised to control mosquitoes. The advertisements for these devices are aimed at the average homeowner. How do you know if they will work? It is unfortunate that many advertisements take advantage of the concerns we have to protect family members from mosquito-borne disease. This factsheet is provided to assist homeowners in smart decision-making when it comes to protecting the health of you and your family.

Mosquitoes can be annoying and sometimes pose a serious risk to public health. In certain areas of the United States, mosquitoes can transmit diseases like West Nile Virus and equine encephalitis. To combat mosquitoes and the public health hazards they present, many federal agencies, states and localities have established mosquito control programs.
