The DeKalb County Board of Health has trapped West Nile virus-positive mosquitoes at 3 locations in the county – Brookhaven, Chamblee and the Redan area of unincorporated DeKalb County. According to the CDC, no data or scientific evidence suggests that mosquitoes spread COVID-19 or other similar coronaviruses.

Due to the virus, the Board of Health will not perform its usual door-to-door canvas of the affected areas. Instead, measures include placing larvicide in areas with standing water, like in storm drains. These actions keep young mosquitoes from becoming flying, biting adults. This year, there have been no human cases of West Nile virus infection confirmed in DeKalb County.

To reduce the spread of West Nile virus and other mosquito-borne diseases, the Board of Health advises people to take the following precautions:

  • Reduce mosquito breeding in your yard by eliminating standing water in gutters and items such as planters, toys, wheelbarrows, and old tires.
  • Discourage mosquitoes from resting in your yard by trimming tall grass, weeds, and vines.
  • Reduce outdoor exposure at dawn and dusk, when the mosquitoes that transmit West Nile virus are most active.
  • Wear a long-sleeved shirt, long pants, and socks outdoors, particularly at dawn and dusk, and in areas with large numbers of mosquitoes.
  • Make sure window and door screens fit tightly to keep out mosquitoes.
  • Use an insect repellent containing DEET, picaridin, oil of lemon eucalyptus, or IR3535. Apply according to label instructions.
  • Spray clothing with products containing permethrin according to label instructions.
