Tarrant County, Texas: In a recent announcement, Tarrant County Public Health (TCPH) has identified the inaugural mosquito sample positive for West Nile Virus (WNV) this year. This discovery signifies the commencement of the West Nile Virus season for 2025.

Understanding West Nile Virus

West Nile Virus is primarily transmitted to humans through infected mosquito bites. Although most individuals exposed to the virus do not exhibit symptoms, approximately 20% may experience mild symptoms, including fever, headaches, body aches, and joint pain. In rare instances, WNV can lead to severe neurological conditions.

Seasonal Activity Trends

Typically, West Nile Virus activity surges from May through October as warmer temperatures boost mosquito populations. This seasonal pattern enhances the importance of monitoring and preventative measures.

Prevention Strategies

To safeguard against mosquito bites and reduce breeding grounds, TCPH advises residents to follow these essential guidelines:

• Utilize EPA-approved insect repellents when outdoors.
• Wear long, loose-fitting clothing, especially during dawn and dusk when mosquitoes are most active.
• Eliminate or treat standing water in residential areas; mosquitoes can breed in as little as a teaspoon of water.
• Whenever feasible, remain indoors during peak mosquito activity hours.

Health Monitoring and Reporting

TCPH continuously monitors for mosquito-borne illnesses, providing a hotline for community concerns: 817-321-4709. For reporting arbovirus cases, residents can reach out at 817-321-5350.
