A person in the Baltimore area has Maryland's first confirmed case of symptomatic West Nile virus infection this year, health officials said.
The Department of Health and Mental Hygiene announced the case Thursday, and warned that virus activity has been detected in mosquitos and birds. Officials said three pools of mosquitos in Montgomery County tested positive for infection. And three sick birds from a Montgomery County wildlife center also tested positive.
Residents are urged to monitor their yards for standing water that can allow mosquitos to breed.
