Mosquito-borne Diseases

Several mosquito-borne viruses circulate in Georgia each year and are capable of causing disease in humans and other animals. The most common mosquito-borne viruses in Georgia include West Nile virus, Eastern Equine encephalitis virus, and LaCrosse virus. Saint Louis encephalitis virus has also been detected in Georgia in the past. Mosquito-borne viruses are most active late spring through early fall in Georgia.

Mosquito-borne viruses can infect birds, horses, and other animals in addition to humans. If public health reports positive birds or horses in your area, or if you see large numbers of mosquitoes, you could be at increased risk of infection. Always take personal protective measures to avoid mosquito bites, especially when mosquito-borne viruses have been identified near you.

Information on Repellents:

The GDPH recommends the use of products containing active ingredients that have been registered with the U.S. Environmental Protection Agency (EPA) for use as repellents applied to skin and clothing.

Of the products registered with the EPA, those containing DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection.

EPA registration means that EPA does not expect the product to cause adverse effects to human health or the environment when used according to the label.
