Georgia is entering the peak season for West Nile virus, prompting experts to urge residents across the state, including here in South Georgia, to take urgent precautions against the mosquito-borne disease. Four human cases of West Nile virus have been reported in Georgia this year, according to the Centers for Disease Control and Prevention. Additionally, mosquito traps in Chatham, DeKalb, and Fulton counties have tested positive for the virus, Georgia’s Department of Public Health confirmed.
West Nile virus is the most common mosquito-borne disease in the U.S. and carries the potential for serious health complications, especially for vulnerable populations. The disease is transmitted by Culex mosquitoes, which are most active between dusk and dawn.
While the Centers for Disease Control and Prevention states that the vast majority of people who develop West Nile virus, about 80%, are asymptomatic, approximately 20% will display flu-like symptoms. However, a small portion of those infected will develop severe symptoms that impact the central nervous system, such as encephalitis or meningitis, according to Dr. Robin Dretler, an infectious disease specialist at Emory Healthcare and a board member with the Infectious Diseases Society of America. Dr. Dretler emphasized that these severe symptoms can be deadly and leave lasting health effects in survivors.
Individuals over the age of 50, organ transplant recipients, and those with cancer or diabetes face the greatest risk of developing severe illness from the virus, Dr. Dretler noted. There is currently no vaccine for West Nile virus, and the disease is not contagious. Most cases can be managed at home with over-the-counter medications to alleviate symptoms. However, Dr. Dretler advises that those who experience more serious symptoms should seek medical treatment immediately. He specified critical warning signs to watch for, including "conjunctivitis (pink eye), stiff neck, confused, weakness in the legs," indicating potential severe complications that require prompt medical attention.
Preventing mosquito bites and reducing breeding grounds are key to avoiding infection. Elmer Gray, a public health specialist at the University of Georgia who studies mosquito control, highlighted that the disease is responsible for about 130 deaths each year in the U.S. Gray remarked, "From an entomological standpoint, we consider those preventable deaths," stressing the personal importance for affected families.
Residents can significantly reduce their risk of infection through simple actions. Gray recommended wearing loose-fitting, light-colored clothing and using EPA-approved insect repellent to help prevent mosquito bites. A critical strategy, according to Gray, is to reduce the amount of stagnant water on personal property, such as rainwater that collects in gutters and flowerpots. He explained that the egg, larvae, and pupal stages of mosquitoes all require water at some point. He stressed the need for extreme diligence, especially this time of year, in eliminating standing water in yards and neighborhoods.
Georgia’s Department of Public Health echoed these recommendations, advising residents to use mosquito repellent and actively reduce potential breeding sites. Nancy Nydam Shirek, a spokesperson for the Department of Public Health, provided specific guidance in a statement: Shirek advised residents to "tip out standing water" in items like flowerpots, planters, children’s toys, wading pools, and buckets after every rainfall or at least once a week. She also recommended disposing of unnecessary items that can hold water, such as old tires, bottles, and cans. These actions are crucial as the region navigates the peak season for West Nile virus, aiming to protect public health and prevent further cases across Georgia.
