West Nile Virus identified in mosquito sample in Chester County
West Chester, PA – The Chester County Health Department is informing residents that a mosquito sample collected in Tredyffrin Township on July 7, 2016 has tested positive for West Nile virus (WNV).
This is the first mosquito sample that has tested positive in Chester County in 2016. The Chester County Health Department sets mosquito traps to collect and test adult mosquitoes for WNV as part of routine surveillance. Traps are placed in highly populated areas, known mosquito breeding areas, and in areas where a resident has previously been identified as having a confirmed case of WNV infection. Traps are also placed in response to complaints from residents regarding high levels of mosquito activity. The Chester County Health Department will continue to monitor these areas as well as surrounding areas and will consider mosquito control activities when appropriate.
The chances of contracting WNV from an infected mosquito are small and chances of becoming seriously ill are even smaller. However, the Chester County Health Department encourages county residents to “Make you and your home a bite-free zone”, reducing the risk of West Nile virus and other mosquito-borne diseases. Because mosquito-borne diseases are spread through the bite of an infected mosquito, residents can reduce their risk by using insect repellent and other personal protection and getting rid of standing water on their property.
The Health Department advises:
Limit outdoor activities at dawn and dusk during warmer months since most types of mosquitoes bite most frequently during these times. Be aware though that some types of mosquitoes bite most frequently during the daytime.
Wear long-sleeved shirts and long pants, and socks. Choose clothing that is light colored and made of tightly woven material.
Stay in places with air conditioning and window and door screens to keep mosquitoes outside.
Sleep under a mosquito bed net if you are overseas or outside. Continue reading
