Savannah’s coastal environment, marsh influence, shaded squares, drainage canals, older neighborhoods, and frequent warm-weather rain can create conditions where mosquitoes thrive. Georgia health officials monitor mosquito-borne diseases statewide, and the Georgia Department of Public Health warned in 2026 that West Nile virus infections were increasing in Georgia.
West Nile virus circulates primarily between birds and mosquitoes. A mosquito becomes infected by feeding on an infected bird, and it can later pass the virus to a person, horse, dog, cat, or other animal through a bite. People and pets do not usually spread the virus to others through everyday contact, and humans and most mammals are considered dead-end hosts.
In Savannah, mosquito breeding sites may include flowerpots, buckets, gutters, birdbaths, fountains, tarps, low areas, storm drains, and other places where water sits for several days. Properties near shaded vegetation or water may experience heavier mosquito pressure, especially in the evening and early morning.
Most people infected with West Nile virus do not develop symptoms. When symptoms occur, they may include fever, headache, body aches, fatigue, joint pain, vomiting, diarrhea, or rash. In a smaller number of cases, the virus can cause severe neurologic illness such as meningitis or encephalitis. Severe cases may involve neck stiffness, confusion, tremors, muscle weakness, paralysis, coma, long-term complications, or death.
There is no specific cure for West Nile virus disease. Mild illness is generally managed with rest, fluids, and symptom relief under medical guidance. Severe illness may require hospitalization, IV fluids, respiratory support, pain control, and careful monitoring.
Dogs and cats can be infected after mosquito bites, but serious illness is uncommon. Horses are more vulnerable to severe disease, so horse owners should consult a veterinarian about West Nile virus vaccination and prevention. Any pet with sudden neurologic signs, weakness, fever, or unusual behavior should receive veterinary attention.
In Savannah, reducing standing water and preventing mosquito bites are the most important steps for lowering West Nile virus risk around homes, businesses, and outdoor living spaces.
