West Nile Virus Positive Activity and Arbovirus Program Update

Mosquito

DeKalb County Board of Health has been notified of its first human case this year of West Nile virus (WNV). This has been a busy year for West Nile virus activity. Surveillance has shown an abundance of the mosquito species that can carry the virus. In fact, more mosquitoes have been collected and tested positive for the virus than in previous years.

DeKalb County’s 2011 season West Nile virus (WNV) positive activity total now consists of 1 human case of WNV infection, 74 WNV positive mosquito collections from 17 WNV positive mosquito trap locations.

Residents throughout DeKalb County should be aware there is a potential for WNV activity anywhere in the county. It is important to take precautions against WNV infection.
Apply insect repellent. DEET (N, N-diethyl-meta-toluamide), picaridin, oil of lemon eucalyptus and IR3535 are effective repellents recommended by the Centers for Disease Control and Prevention. For more information, please see:

When possible, wear long sleeves, long pants and socks. Clothing may also be treated with permethrin.
Use extra care when mosquitoes are most active. The mosquitoes that are most likely to carry West Nile virus are more active from dusk to dawn.
Remove any water holding containers.
Attached is an Arbovirus Program Update highlighting program activity for the 2011 season, a map showing WNV positive activity and a press release.
