Dallas County Witnesses West Nile Virus Outbreak in Three Cities

Dallas County Health and Human Services has confirmed the presence of West Nile virus in mosquito populations of Irving, Richardson, and Rowlett. The positive test results were obtained from mosquito pools in these cities, indicating ongoing transmission risk in the areas.

This development comes in the wake of Tarrant County Public Health's confirmation of a WNV-positive mosquito sample on May 8, signaling the onset of the West Nile virus season in North Texas, which typically lasts from May through October.

As summer approaches, the virus, which thrives in heat-loving mosquitoes, represents a potential health concern. Most human infections result from mosquito bites.

Tarrant County Public Health stated that most infected individuals exhibit symptoms. While the majority of infected people experience only mild symptoms such as fever, headache, body aches, or joint pain, the virus can, in rare cases, cause serious illness affecting the brain or nervous system.

Although WNV can be transmitted through blood transfusions, organ transplants, breastfeeding, and mother-to-child transmission, it cannot be passed from person to person through touch or saliva.

In an effort to prevent the virus' spread, Dallas County Health and Human Services advocates for adhering to the 4D's:

• Apply insect repellents containing DEET or other EPA-approved repellants daily and consistently.
• Dress in long, loose, and light-colored clothing while outdoors.
• Eliminate standing water both at homes and public spaces to disrupt mosquito breeding.
• Limit outdoor activities during dusk and dawn hours when mosquitoes are most active.

In response to the positive test results, the cities of Richardson, Irving, and Rowlett have initiated targeted spraying in high-risk zones to curb the further spread of WNV. No human cases have been reported so far this year in the Dallas area.

Texas residents are encouraged to stay vigilant and consult with their healthcare providers if experiencing symptoms suggestive of West Nile virus infection. As the virus continues to circulate, local health authorities will maintain robust mosquito control efforts, public education campaigns, and personal protective measures to safeguard public health.
