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 to detect viruses that could be transmitted to people. The information is used to direct insecticide efforts and to warn residents to take precautions.
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.
WNV is transmitted to humans by the bite of infected mosquitoes. Many people who are infected with the virus have no symptoms. Some may have mild to moderate symptoms including fever, headache, body aches, vomiting, diarrhea, or rash. Severe cases can lead to serious, sometimes fatal, illness.
There is no vaccine or cure for WNV, 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
Mosquitoes are most active at dusk and dawn. If you can, avoid going outside at dusk and dawn to reduce your chance of being bitten.
Dress
Wear loose-fitting, long sleeved shirts and pants to reduce the amount of exposed skin. If the mosquitoes can’t get to your skin, they can’t bite you.
DEET
Any skin that is exposed should be covered with an insect repellent containing DEET, which is the most effective repellent against mosquito bites. Be sure to follow the instructions on the label regarding how to apply and how often to reapply.
Drain
Mosquitoes need standing water for breeding, so be sure to empty any containers holding stagnant water, such as buckets, barrels, flowerpots, and tarps. Be especially mindful after a rain, and toss any standing water to discourage mosquito breeding around your home.
Doors
Make sure doors and windows are in good repair and fit tightly. If you have screens on your windows and doors, be sure to fix any rips or tears so mosquitoes can’t get through the screens and into your home.
