West Nile Virus: Beware the Buzz

Recent heavy rainfall across Texas has triggered a surge in mosquito populations, sparking alarm among experts at the Texas A&M AgriLife Extension Service. With the increased risk of West Nile Virus (WNV), a prevalent mosquito-borne disease in the United States, individuals, pet owners, and livestock keepers are urged to take precautionary measures. 

J.D. Ragland, Ph.D., an agriculture and natural resources agent, has confirmed positive WNV cases in Randall County. In response, Ragland advises everyone to remain vigilant and take steps to minimize the risk of transmission. 

Eliminating standing water in lakes, trenches, and even household items like flowerpots and wheelbarrows is crucial. Backyard pools should be drained if not in use, and household pets should be monitored closely, ideally limiting their access to indoor spaces. 

Wearing long sleeves and pants can provide additional protection, especially during the active feeding times of mosquitoes at dawn and dusk. Regularly applying EPA-registered mosquito repellents containing DEET, oil of lemon eucalyptus, or picaridin is strongly recommended. 

Animals can be safeguarded through annual vaccinations against WNV, which are offered at most veterinarian hospitals. For horses, it is advisable to administer the initial dose as soon as possible if they have not been previously vaccinated. Already vaccinated horses should receive a spring booster shot or appropriate immunization ahead of mosquito season. 

Recognizing the symptoms of WNV infection is crucial. Horses may exhibit a high fever, incoordination, inability to stand, loss of appetite, or acute death. In humans, symptoms may include high fever, headache, neck stiffness, disorientation, muscle weakness, and, in severe cases, convulsions, numbness, paralysis, and coma. 

To stay informed, refer to the Centers for Disease Control and Prevention's guidelines on WNV safety precautions. Ongoing WNV testing is being conducted throughout Texas, with the Texas Department of State Health Services (DSHS) reporting the latest West Nile activity in various counties, which can be found here: DSHS West Nile graph. 

As health officials work to combat the WNV outbreak, it is vital for individuals, pet owners, and livestock keepers to remain proactive in reducing mosquito populations and taking necessary precautions to protect themselves and their animals from this airborne threat.
