West Nile Virus Positive Mosquito Sample Found in Clay County

The Clay County Health Department collected a West Nile virus positive mosquito sample on June 21st from Louisville.

Confirmation of a West Nile Virus positive mosquito sample means that the virus is circulating in the community and there is a heightened risk of infection for humans. Residents are urged to take the necessary precautions to protect themselves from mosquito bites. It is important to remember the three R’s – reduce your exposure to mosquitoes, repel them by wearing insect repellant, and report areas where mosquitoes typically breed.

West Nile virus is transmitted to humans through the bite of an infected mosquito. Mosquitoes pick up the virus by feeding on an infected bird. The illness is not spread from person-to-person.  Most people infected with West Nile virus show no symptoms. However, some people may experience fever, nausea, headache, and muscle aches. Symptoms may last from a few days to a few weeks. In rare cases, severe illness including meningitis or encephalitis, or even death, can occur. People older than 50 are at higher risk for severe illness from West Nile Virus.

The Clay County Health Department is conducting surveillance for West Nile virus throughout the county. Surveillance activities include laboratory tests on mosquito batches, the submission of dead crows, blue jays, robins, and other perching birds, and responding to concerns of mosquito production sites.  

If you find a dead perching bird, or would like more information on West Nile virus, contact the Clay County Health Department at 662-4406 or visit their website www.healthdept.org.
