Pa. confirms year’s first detections of West Nile

HARRISBURG, Pa. (WHTM) – A mosquito sample collected in York County has tested positive for West Nile virus.

The mosquito collected May 22 in Springettsbury Township is one of the first 2015 detections of West Nile, according to a Health Department news release.

The virus was also found in a bird  found May 26 in Harris Township, Centre County.

Certain mosquito species carry the virus, which may cause humans to contract West Nile fever or West Nile encephalitis, an infection that can result in inflammation of the brain.

Last year, West Nile Virus was detected in 39 counties and resulted in 13 human cases, including one fatality.

Older adults and those with compromised immune systems are at the highest risk of becoming ill.
