First 2025 West Nile Cases Found in Texas, NC

The first human cases of West Nile virus in 2025 have been confirmed in Hays County, Texas, and Durham County, North Carolina, according to health officials. No positive mosquito pools have been detected in Hays County, but the confirmed case highlights the need for prevention, especially among vulnerable populations. In Durham County, the case is the first since 2022, while mosquito surveillance in Pitt County, NC, has detected West Nile-infected mosquitoes. Most people infected are asymptomatic, but about 20% may develop mild symptoms and a small fraction can experience severe neurological complications. Health departments are urging the use of EPA-approved repellents, protective clothing, and elimination of standing water to reduce risk. Surveillance and mosquito control efforts are being intensified as officials emphasize continued vigilance during the summer months.
