Summary Studies reporting tick infection rates for Powassan virus ( POWV ), an emerging zoonotic arthropod‐borne pathogen responsible for POWV disease in the Commonwealth of Pennsylvania, are limited. To determine the presence and ascertain a statewide prevalence of POWV , ticks were collected from 9,912 hunter‐harvested white‐tailed deer ( Odocoileus virginianus ) heads presented to six regional Pennsylvania Game Commission Chronic Wasting Disease sampling stations in early December of 2013, 2014 and 2015. Of the 2,973 ticks recovered, 1,990 (66.9%) were identified as adult Ixodes scapularis (black‐legged tick). The 1,990 I. scapularis ticks were PCR ‐tested for the presence of POWV . The ticks had a statewide Powassan/deer tick virus infection rate of 0.05%, providing evidence of this pathogen in Pennsylvania's adult I. scapularis ticks and supporting the need for more comprehensive pathogen prevalence assessment strategies, as well as increased public health awareness for this emerging zoonotic arthropod‐borne pathogen of public health concern.
