West Nile Virus Detected in Nueces County Mosquito Sample

Corpus Christi, TX, October 6, 2026 —
Officials in Nueces County have confirmed the detection of West Nile virus (WNV) in a mosquito sample. The sample was collected in an area near Chapman Ranch.
The discovery marks the first identification of the virus in the county for the current season, according to available information. West Nile virus is transmitted to humans through the bite of infected mosquitoes. While many people infected with WNV may show no symptoms, some can develop severe illness, including neurological disease.
The county has not provided details regarding the specific species of mosquito that tested positive or the precise date of collection for the sample. Information on any public health advisories or recommended preventative measures by county officials was also not immediately available in the provided summary.
West Nile virus is typically found in tropical and subtropical regions. Mosquitoes that feed on infected birds can become carriers and then transmit the virus to humans and other animals when they bite.
Symptoms of West Nile virus disease can appear anywhere from 3 to 14 days after an infected mosquito bite. The majority of human infections, approximately 80%, are asymptomatic. About 20% of people who become infected develop West Nile fever, with symptoms that can include fever, headache, body aches, joint pains, vomiting, diarrhea, and rash. Less than 1% of infected people develop a severe neurological illness, such as encephalitis or meningitis, or West Nile neuroinvasive disease. This severe form of illness can be fatal.
Health authorities generally advise residents to take precautions to avoid mosquito bites, such as using insect repellent, wearing long sleeves and pants during dawn and dusk when mosquitoes are most active, and eliminating standing water around homes where mosquitoes can breed.
Further details regarding the extent of the virus’s presence, specific risk areas within the county, and ongoing surveillance efforts were not specified in the initial confirmation.
