Central Texas Confirms First West Nile Virus Case

Following a significant outbreak in 2024, the first confirmed case of West Nile virus illness was reported on June 24, 2025, in a resident of Brazos County, Texas.

This Texas Department of State Health Services (DSHS) announcement raises concerns for all Texans as virus-carrying mosquitoes remain active into December.

There were 455 cases of West Nile disease in Texas in 2024 and 56 related fatalities.

Over the last five years, Texas has had 929 West Nile cases and 122 deaths.

“Texans should be aware that mosquitoes transmit disease, and some of these illnesses, like West Nile and dengue, can be severe,” said DSHS  Commissioner Jennifer A. Shuford, MD, MPH. “But taking steps to prevent mosquito bites and eliminating mosquito breeding areas around homes are proactive measures that can reduce the risk of mosquito-borne illness.”

Infected mosquitoes transmit West Nile virus after biting. Although 80% of people exposed to the virus do not develop symptoms, the remaining 20% will experience symptoms such as fever, nausea, headache, fatigue, and muscle and joint pain.

Less than one percent of those exposed will suffer from West Nile neuroinvasive disease, which affects the nervous system and can cause disorientation, neck stiffness, tremors, paralysis, convulsions, and even death.

DSHS urges anyone experiencing West Nile symptoms to contact their health care provider and mention any exposure to mosquitoes.

As of July 3, 2025, no vaccine for West Nile virus exists.
