The Brazos County Health District (BCHD) conducts Mosquito Surveillance with weekly trapping in both Cities of Bryan and College Station, beginning each May through the end of October to monitor for the presence of West Nile Virus, St Louis Encephalitis Virus, and Eastern Equine Encephalitis Virus.
BCHD staff also collects mosquitoes trapped by members of the Brazos Valley Vector Collaborative (BVVC) in the six adjacent counties of Burleson, Grimes, Leon, Madison, Robertson, and Washington. Traps are set by BVVC members every other week and samples are collected, prepared and shipped to the Texas DSHS Arbovirus Laboratory in Austin by the BCHD.
Brazos County Health District officials have notified the other members of the Vector Surveillance and Control Partnership along with the City of Bryan, City of College Station, Texas A&M University, and affected surrounding counties.
Enhanced surveillance including additional traps and larvicide treatments of confirmed breeding habitat in the area of the positive sample collection will begin as specified in the Brazos County
Health District Phased Response Guidelines. Residents in all areas of Bryan, College Station, the Brazos Valley area, and surrounding counties should empty and eliminate any standing water in containers on their property and ensure that lawn irrigation and onsite sewage systems are functioning properly.
In response to the first human case of West Nile Virus in Brazos County in 2024, BCHD will follow the protocol outlined in the Phased Response Guidelines. This Phased Response includes but is not limited to setting additional traps and increased larvicide application of breeding habitats in the impacted zip code. BCHD will continue to educate the public on ways to protect themselves and monitor the area.
There are no medications to treat, or vaccines to prevent West Nile Virus infection. All Brazos County residents are urged to use the 4D’s to reduce exposure to biting mosquitoes:
• DEET All day, Every Day: Whenever outside, use and reapply insect repellents that have the active ingredient DEET or other EPA-registered repellents and always follow label instructions.
• Dress: Wear long, loose, and light-colored clothing outside.
• Dusk and Dawn: Limit spending time outdoors when mosquitoes are most active.
• Drain: Drain or treat with larvicide all standing water in and around your home or workplace where mosquitoes could lay eggs.
West Nile Virus is transmitted through the bite of infected mosquitoes. Most people exposed to the virus do not get sick, but about 20% develop symptoms like headache, fever, body aches, joint pains, nausea, and fatigue. In a very small portion, less than one percent, the virus affects the nervous system, leading to a more serious illness that can cause neck stiffness, disorientation, tremors, convulsions, paralysis, and even death.
