Fort Bend County West Nile virus activity has led to the county’s first confirmed human case of 2026, health officials announced. Fort Bend County Health & Human Services said the case involves neuroinvasive West Nile virus in a resident of ZIP code 77478.
Fort Bend County West Nile Virus Case Confirmed
Fort Bend County Health & Human Services confirmed the case through its Epidemiology Division. To protect the resident’s privacy, officials said no additional patient information will be released.
The county also reported increased mosquito activity tied to the virus. As of the announcement, the Environmental Health Division’s Vector Control Program had identified 36 mosquito samples that tested positive for West Nile virus in Fort Bend County.
Dr. Letosha Gale-Lowe, Director and Local Health Authority for Fort Bend County Health & Human Services, said the confirmed human case highlights the need for residents to protect themselves from mosquito bites.
“This confirmed human case underscores the importance of preventing mosquito bites, as mosquitoes can spread diseases such as West Nile virus and dengue,” Gale-Lowe said. “The best way to protect yourself and your family is to use insect repellent, wear protective clothing outdoors, eliminate standing water around your home and avoid being outdoors during dusk and dawn, when mosquitos are most active.”
How West Nile Virus Spreads
West Nile virus spreads through the bite of an infected mosquito. However, most people who get infected do not develop symptoms.
About one in five infected people develop a fever. Symptoms can also include headache, body aches, joint pain, vomiting, diarrhea or rash.
In rare cases, West Nile virus can cause serious neurological illness. Because of that risk, health officials urge extra caution for adults over age 60 and people with certain underlying medical conditions.
Mosquito Testing Guides Fort Bend County Response
Fort Bend County’s Mosquito and Vector Control Program conducts mosquito surveillance year-round. Through that work, the program monitors mosquito populations and tests for West Nile virus activity throughout the county.
Positive mosquito samples help guide targeted mosquito control efforts. Those efforts may include additional surveillance and treatment in areas where officials identify virus activity.
Meanwhile, health officials said residents should remain alert during warmer months, when mosquitoes are most active. Regular prevention steps can help reduce exposure around homes, yards and neighborhoods.
The 4 Ds of Mosquito Safety
Fort Bend County officials urge residents to follow the 4 “Ds” of mosquito safety.
Avoid dusk and dawn, when mosquitoes are most active.
Drain standing water around homes and yards.
Dress in long sleeves and long pants when feasible.
Defend against bites by using repellent containing DEET or another CDC-approved mosquito repellent.
The first confirmed Fort Bend County West Nile virus case of 2026 is a reminder for residents to take simple prevention steps. Reducing standing water, using insect repellent and wearing protective clothing can help lower the risk for families and neighborhoods.
