Lehigh County has recorded its first case of West Nile virus this year.

A mosquito collected in Lower Macungie Township on July 17 tested positive for the virus, the Pennsylvania Department of Environmental Protection announced Wednesday.

The DEP has collected 408 mosquitoes in Lehigh County, with 175 being tested for West Nile so far this year, officials said.

As of Wednesday, the DEP said Lehigh and Berks were two of 15 counties in Pennsylvania considered to be "low risk" for the virus. Northampton County, which has had two mosquitoes test positive for West Nile, was at moderate risk.

All other counties currently under surveillance for West Nile are considered to be at a "remote risk."
