New positive mosquito pools for West Nile Virus

The Tennessee Department of Health Laboratory in Nashville identified nineteen additional mosquito pools testing positive for West Nile Virus in Shelby County since the last report on July 9. This indicates that West Nile Virus activity has significantly increased in Shelby County, resulting in the increased risk of human infection. The Memphis and Shelby County Health Department’s Vector Control Section will begin spraying in heavily affected areas for adult mosquitoes (adulticiding) as soon as weather conditions permit. Residents in the affected areas will be notified before the Health Department begins spraying. All residents in Shelby County are at risk of mosquito bites and should take appropriate precautions. The Memphis and Shelby County Health Department strongly encourages everyone to take extra precautions against mosquito bites. The recent rainfall throughout Shelby County may have washed out some of the areas where mosquito eggs were ready to hatch, but the rain will also increase the potential for more mosquito-breeding in any standing water that does not evaporate or drain off well. All residents are strongly encouraged to eliminate any standing water around homes and businesses. At the same time residents should take measures to protect themselves, including the safe use of a mosquito repellant containing DEET. The battle against West Nile Virus in our community cannot be won through just the efforts of the Health Department. Citizens are urged to minimize the risk of being bitten by mosquitoes by following precautions to protect themselves from possible exposure to infected mosquitoes, including the safe use of mosquito repellents. Residents can contact the West Nile Virus Hotline at (901) 544-7503 for more information about bird testing or general questions relating to West Nile. Individuals outside of Shelby County should contact their state or local health department for information regarding bird surveillance.
