A mosquito sample collected by Chatham County Mosquito Control has tested positive for West Nile Virus (WNV). Mosquito Control routinely collects and samples mosquitoes throughout Chatham County. The infected mosquitos were collected from the south side of Savannah. This is the first positive WNV test in the Chatham County mosquito population this year. Mosquito Control is treating the area with insecticide.
Last week, Mosquito Control’s routine testing program also confirmed Eastern Equine Encephalitis (EEE) in a chicken in West Savannah. EEE is another mosquito-borne virus that can infect humans. The testing program acts as an early alert system for detecting these viruses in the mosquito population. The information is used to direct insecticide efforts and to warn residents to take precautions.
WNV and EEE are transmitted to humans by the bite of infected mosquitoes. Many people who are infected with these viruses have no symptoms, but severe cases can lead to serious, sometimes fatal, illness.
There is no vaccine or cure for WNV or EEE, so prevention is key. All residents should take steps to avoid mosquito bites and eliminate standing water. You can reduce your risk of infection by following the 5Ds of mosquito bite prevention:
- Dusk/Dawn – Avoid dusk and dawn activities during the summer when mosquitoes are most active.
- Dress – Wear loose-fitting, long-sleeved shirts and pants to reduce the amount of exposed skin.
- DEET – Cover exposed skin with an insect repellent containing the DEET, which is the most effective repellent against mosquito bites.
- Drain – Empty any containers holding standing water – buckets, barrels, flowerpots, tarps – because they are breeding grounds for virus-carrying mosquitoes.
- Doors – Make sure doors and windows are in good repair and fit tightly, and fix torn or damaged screens to keep mosquitoes out of the house.
