Washington- US–
The City of San Antonio Metropolitan Health District (Metro Health) has confirmed the first positive mosquito sample for West Nile Virus (WNV) for the 2025 season. The sample was collected from a mosquito trap located in the north central part of the city, near the intersection of West Avenue and Blanco Road.
In response, Metro Health has announced plans to conduct targeted mosquito-spraying operations in the affected area. The public is advised to remain indoors during the scheduled treatment time on Wednesday, August 6, 2025, at 3 a.m.
West Nile Virus is a mosquito-borne illness that typically shows no symptoms in most people. However, about one in five people who are infected may develop a fever, headache, body aches, joint pain, or a rash. In a small number of cases, the virus can lead to a severe and potentially life-threatening illness that affects the central nervous system, with symptoms including a high fever, neck stiffness, disorientation, or paralysis.
To help reduce the risk of infection, public health officials are strongly advising residents to take preventative measures:
* Drain Standing Water: Empty any containers that can hold water, like buckets, planters, or birdbaths. Mosquitoes can breed in even small amounts of water.
* Use Repellent: Apply EPA-registered insect repellents containing DEET or Picaridin on exposed skin when outdoors.
* Wear Protective Clothing: When outside, especially during dusk and dawn, wear long-sleeved shirts, long pants, and socks to minimize exposed skin.
* Check Screens: Ensure all windows and doors have secure screens to prevent mosquitoes from getting inside your home.
This discovery of WNV-positive mosquitoes serves as a critical reminder for residents to be vigilant and take proactive steps to protect themselves and their families from mosquito-borne illnesses.
