A previously reported possible case of West Nile virus in Harris County has been ruled out, according to the Texas Department of State Health Services.
The adult male from eastern Harris County showed symptoms consistent with WNV, but required lab testing was not performed by the treatment facility. Without that testing, DSHS determined the case does not meet confirmation standards.
No Confirmed WNV Cases in Harris County
As of now, there are no confirmed human cases of West Nile virus in Harris County. Harris County Public Health remains on alert and continues to monitor mosquito-borne illnesses across the region.
Help Prevent Mosquito Bites: Follow the “3 Ts”
HCPH urges all residents to take steps to protect themselves from mosquito bites, especially in the warmer months. Their mosquito prevention strategy is based on the “3 Ts”:
- Tip – Remove standing water from items like flowerpots, buckets, birdbaths, and tires where mosquitoes breed.
- Toss – Get rid of unused objects that can collect water.
- Take Action – Wear long sleeves and pants outside, use EPA-approved insect repellent, and check that window and door screens are intact.
