West Nile in PA

West Nile  in PA

Reading, PA (WENY)---The first mosquito carrying the West Nile virus has been detected in Pennsylvania.

The virus was found near Reading in South-eastern Pennsylvania. It's the earliest detection since testing began in 2000.

Usually the virus carrying insects don't show up until mid-June, but this year's unseasonably warm weather accelerated the cycle.

In humans, the virus can result in inflammation of the brain. Officials say most infected people do not become ill, but older adults and people with weak immune systems have the highest risk of getting sick.
