The PA Department of Health has issued Health Advisory 576 regarding 2021 West Nile Virus (WNV). The first WNV-positive pools were identified in Pennsylvania in Lebanon and Beaver counties for the 2021 arbovirus season through the routine seasonal monitoring conducted by the Pennsylvania Department of Environmental Protection (DEP) West Nile virus (WNV) surveillance program. This indicates that WNV may have begun to circulate in Pennsylvania. Risk of human WNV infection is likely to remain elevated over the next several months. This is a reminder to consider the diagnosis of arboviral infection in persons presenting with undifferentiated febrile illness or signs of meningoencephalitis.
