Atlantic County public health officials announced that testing of mosquito samples in July 2026 confirmed the presence of West Nile virus in five towns throughout the county. The detection was made through routine laboratory analysis conducted by the county’s mosquito control program, which flagged the virus after a series of collections from multiple locations.
County mosquito control officials said the positive results triggered an immediate response, including intensified surveillance of mosquito populations and expanded testing in surrounding areas. The agencies are working together to map the locations where the virus was identified and to monitor any changes in mosquito activity that could affect the spread of the disease.
Public health officials are urging residents of the affected towns to take additional steps to avoid mosquito bites. Recommended actions include wearing long sleeves and pants, applying EPA‑registered insect repellent, and ensuring that standing water is eliminated from yards and property. The guidance is consistent with standard precautions for West Nile virus prevention and is being distributed through local health department alerts, flyers, and community outreach events.
The county’s ongoing monitoring program continues to collect mosquito samples on a regular schedule. Health officials stress that the current findings are part of an established surveillance system designed to detect West Nile virus early and to inform timely public‑health interventions. Outreach efforts are also focused on educating the public about the symptoms of West Nile infection and the importance of seeking medical care if they experience fever, headache, or other related signs.
No human cases have been reported in the county as of the July 2026 update. Authorities will keep the public informed as additional testing results become available and will adjust control measures as needed to reduce the risk of transmission.
