Maryland officials are spraying for mosquitoes.
Maryland is spraying some areas of Anne Arundel County to control mosquitoes after West Nile virus was detected.
The state Department of Agriculture says moisture from heavy rains earlier this summer hatched a high concentration of mosquitoes that can spread the disease. Authorities say the spraying last night targeted an area within a one-mile radius around the home of a person who was infected with the virus.
WJZ TV in Baltimore reports the areas sprayed include parts of St. Margaret's, St. Margaret's Farm, and Old Bottom Estates. Sprayers are expected to be back out tonight.
While most of those who get infected with West Nile don't show any symptoms or ill effects, about 20 percent experience symptoms including fever, headache, body aches, rashes, and swollen lymph glands. Less than 1 percent of those exposed develop more severe infections and in rare instances, the virus can be fatal.
