SAVANNAH, Ga. (WSAV) – The Chatham County Health Department reports that West Nile Virus (WNV) has been detected in mosquito populations in Chatham County.
The infected mosquito was collected from just south of Savannah, marking the first time this year that a mosquito population in Chatham County has tested positive for WNV.
Mosquito control companies are spraying the area with insecticides.
WNV is transmitted to humans through the bite of an infected mosquito. Many people infected with the virus do not experience any symptoms. Others experience mild to moderate symptoms, such as fever, headache, body aches, vomiting, diarrhea, and a rash. Severe cases can lead to serious and sometimes fatal illness.
There is no vaccine or treatment for WNV, so prevention is key. All residents should take measures to avoid mosquito bites and eliminate standing water. Following the 5 D’s to avoid mosquito bites can help reduce the risk of infection.
- Dusk/Dawn – Avoid activity at dusk and dawn during the summer months when mosquitoes are most active.
- Clothing – Wear loose fitting, long sleeved shirts and trousers to reduce exposed skin.
- DEET – Apply insect repellent containing DEET to exposed skin, the most effective repellent against mosquito bites.
- Drain – Empty all containers that hold water, such as buckets, barrels, flower pots and tarps, as these provide breeding grounds for mosquitoes that carry the virus.
- Doors – Make sure your doors and windows are in good repair and securely installed, and repair any torn or damaged screens to stop mosquitoes from getting inside your home.
Mosquito control units routinely collect and sample mosquitoes throughout Chatham County to detect viruses that can infect humans.
