Mosquitoes in Anne Arundel County carry West Nile virus

Mosquitoes trapped in Anne Arundel County, Maryland, have tested positive for West Nile virus, marking the first identification of the virus in mosquitoes in the U.S. this year. No human cases have been reported. The Maryland Department of Agriculture will spray affected areas, and while the Environmental Protection Agency has deemed it safe, outdoor activity is advised against during spraying. The spraying is scheduled for July 23 near Crain Highway and Davidsonville Road. West Nile virus is transmitted through mosquito bites, with about 20% of those exposed developing symptoms such as headache, fever, and fatigue.
