Mosquitoes carrying the West Nile (L.C.) Virus have been found in Anne Arundel County, the third positive test in Maryland this year after years of declines.

“Mosquitoes that are positive for West Nile virus are a rare event; less than one-tenth of 1 percent are positive,” said Mike Cantwell, entomologist for the Maryland Department of Agriculture. “Our peak year was in 2003, and since that time, the incidence of West Nile virus in mosquitoes and in human cases has been declining.”
