A mosquito collected in Washington Township on July 11 tested positive for the virus, the Pennsylvania Department of Environmental Protection announced Thursday.
The DEP has collected 596 mosquitoes in Berks County so far this year, testing 177 of them for West Nile virus, officials said.
Berks recorded its first mosquito with West Nile virus on Wednesday. It was found in Cumru Township on July 10.
