Information about the West Nile Virus

West Nile Virus in an infection spread by certain types of mosquitoes, most commonly by the Culex mosquito. An example of the virus transmission is when an infected mosquito bites a human or another animal after biting an infected bird. With the decline of daily temperatures, mosquito biting and flight is significantly reduced. However, if warmer weather returns, increased temperatures may cause mosquito-biting activity to reoccur.  

Residents should keep their grass cut lower than 8 inches and remove all standing water. When outdoors, wear long sleeves and pants and protect all uncovered areas of the body using mosquito spray containing deet. 

Most people who are bitten by an infected mosquito do not display any symptoms. In rare cases, infection can lead to encephalitis, myelitis or meningitis. The incubation period is 3-14 days.
