First West Nile-infected mosquitoes found in Allegheny County
Allegheny County health officials identified the first mosquitoes to test positive for West Nile virus this week.
The Allegheny County Health Department reported Thursday that the infected mosquitoes were from Point Breeze.
Last year, the first West Nile-infected mosquitoes were found in May.
Mosquito samples have already tested positive for the virus in Lawrence, Beaver and Erie counties, according to the state Department of Health. Fifteen other counties, mostly in Southeastern Pennsylvania, reported positive samples.
No human cases of the virus have been diagnosed in the state this year. Allegheny County had two nonfatal cases last year.
The Allegheny County Health Department is urging residents to keep clean potential mosquito breeding sites that hold standing water, including tires, buckets, flowerpots, junk piles and cans, swimming pools, gutters and birdbaths.
