West Nile Virus

On April 12, 2021 the Centre County West Nile Virus Surveillance and Control season began.  West Nile Virus (WNV) is a mosquito borne disease that produces severe neurological symptons in about 1% of humans that become infected.  The bite of a mosquito infected with WNV is the way in which humans acquire the disease.  There are about 50 species of mosquitoes in PA, and of these, 12 are capable of infecting humans with WNV.

The Surveillance and Control Program is managed by the Centre County Planning & Community Development Office.

The program consists of trapping larval and adult mosquitoes in populated areas of the County and shipping them to PA DEP in Harrisburg, where they are identified as to species, and the adults of species capable of transmitting WNV are tested for the virus. 

Additionally, they are responsbile for collecting and submitting dead birds for WNV testing. 

In Centre County in 2020 there were 4 positive tests for WNV, 0 were from birds, 4 were from mosquitoes, and 0 were from horses. 

We are asking people to please do their part by eliminating sources of standing water such as unused swimming pools, stagnant ornamental ponds, poorly functioning roof gutters, and especially used tires. 

Between May and the end of September, adult mosquito trapping will be periodically conducted in our municipality.

If you have any question, concerns, or comments, please contact the County Planning & Community Development Office.
