Atlanta Park Closed Due to West Nile Virus Mosquitoes
Old National Park in Atlanta has been closed due to mosquitoes testing positive for West Nile virus, according to Fulton health officials.
Atlanta, GA, August 11, 2026 —
Old National Park in Atlanta has been temporarily closed following the detection of mosquitoes that have tested positive for West Nile virus. The closure was announced by Fulton County health officials.
The presence of the virus in the local mosquito population led health authorities to take immediate action to protect public health. While the specific timeline for the park’s reopening was not provided, officials indicated that the closure is a precautionary measure.
West Nile virus is typically spread to people through the bite of an infected mosquito. Most people infected with West Nile virus do not develop any symptoms. However, about 1 in 5 people who are infected develop West Nile fever, which can include fever, headache, body aches, joint aches, vomiting, diarrhea, or rash. About 1 in 150 people infected develop a serious neurologic illness, such as encephalitis or meningitis, or WNND (West Nile Neuroinvasive Disease). Severe symptoms can include high fever, neck stiffness, disorientation, coma, tremors, seizures, or paralysis. These severe symptoms may be permanent. Older adults and people with weakened immune systems are at a higher risk of developing severe illness.
Fulton health officials have not released specific details regarding the number of mosquitoes tested or the exact locations within the park where the positive samples were collected. Further information regarding the park’s status and any ongoing public health advisories is expected to be released by the department.
