Georgia health officials have confirmed eight human cases of West Nile virus and one death in 2026, warning that infections are likely to rise while mosquito season continues through October. Positive mosquito traps in Chatham, Fulton and DeKalb counties show activity in both coastal and metro Atlanta areas, making prevention relevant well beyond a single community.
The Georgia Department of Public Health issued the statewide alert September 16. The agency did not identify the patients or assign all human cases to particular counties, so the confirmed mosquito-trap locations should not be read as a complete map of infection risk. The key operating fact is the calendar: Georgia’s mosquito season typically lasts through October, leaving several weeks for additional exposure.
West Nile is spread primarily through bites from infected mosquitoes. Most infections are silent, but the Centers for Disease Control and Prevention says about 20% of infected people develop a flu-like illness that can include fever, headache, body aches, joint pain, vomiting, diarrhea or rash. Symptoms generally begin two to six days after a bite, though the window can extend to 14 days.
Severe illness is uncommon but consequential. Fewer than 1% of infected people develop disease affecting the central nervous system, according to CDC. Risk rises with age and is higher for people with certain chronic conditions or weakened immune systems. Immediate medical attention is warranted for high fever, neck stiffness, confusion, tremors or muscle weakness. There is no licensed human vaccine and no specific medicine that eliminates the infection; treatment is supportive.
DPH recommends using an EPA-registered repellent, wearing loose-fitting long sleeves and pants, and keeping window and door screens in good repair. The agency specifically lists products containing DEET at 20% to 30%, picaridin, IR3535 or oil of lemon eucalyptus. The Environmental Protection Agency provides a repellent search tool so residents can compare products and application times rather than relying on labels such as “natural” or “strong.” Because mosquitoes can bite during the day as well as at night, protection should be based on exposure and local conditions, not only on time of day.
Household mosquito control matters, too. DPH urges residents to empty water-holding containers after rain or at least weekly, including flowerpots, planters, buckets, toys and wading pools. The CDC’s prevention guidance adds that permanent standing water may be treated with labeled larvicides and that local mosquito-control programs can advise on larger problems.
The alert does not mean every mosquito carries West Nile, and a positive trap does not establish that a nearby person has been infected. It does mean the virus is circulating as outdoor fall activities continue. Georgians with concerning symptoms should contact a health care provider; questions about local activity and control can also be directed to county health departments or mosquito-control programs.
