York County West Nile Virus Program

Waste Tires | WNV Links | York County Data

The residents and visitors of York County continue to be living in an area of concern for the risk of West Nile Virus.  Based on 29 pools of mosquitoes collected in 2008 testing positive, York County ranks eighth out of 67 Counties in Pennsylvania.  For mosquito surveillance, the Penn State Cooperative Extension staff ranks second, submitting 73,135 adult and larval mosquitoes for identification and testing. In 2008, there were no confirmed human cases of West Nile Encephalitis, but there have been human cases of West Nile Virus every year in York County since 2002.

We want to remind all York County residents that West Nile Virus is now an international health issue extending through all 48 States, southern Canada, Central and South America.  Everyone can take simple measures to reduce the number of mosquitoes around your home, neighborhood, farm, and work by eliminating standing water, in which mosquitoes can breed.  Please visit the links below for additional information.  In 2009, we will continue our efforts to educate the public, train municipal workers, and conduct county-wide surveillance and management of mosquito populations. 

Residents of York County are now experiencing issues related to the exotic Asian Tiger mosquito (Aedes albopictus). This is a daytime active, repeat biting mosquito. Small containers, trash and clutter are preferred egg laying habitat by this mosquito. Once water is introduced from rainfall or other sources the mosquito eggs hatch. Community wide clean-up efforts are the best way to eliminate this aggressive mosquito. Issues with Asian Tiger mosquitoes should be reported to the York County West Nile Virus Program and all efforts will be made to perform surveillance in your area of York County.

Report Dead Birds Online or in York County call (717)-840-2375.  For 2009, dead bird collection will occur from May 1st through October 1st.  Collection will only be of Corvids (Blue Jay, Crow, & Raven) and Raptors - Birds of Prey (Hawk, Owl, Falcon, etc.)

Waste Tires

Waste tires are good at holding water, offering mosquitoes a great place to breed. Mosquitoes mature rapidly given the right conditions. So, even in drought years, rainwater can stay in tires long enough to generate mosquitoes. Dispose of tires properly; don't leave them outside to breed mosquitoes.
