The City of Denton has confirmed the presence of West Nile virus in mosquitoes at Denia Park and South Lakes Park. Mosquitoes collected last week at these sites tested positive for the virus. Despite the findings, no human cases have been reported so far.
With multiple mosquito pools testing positive, Denton has elevated the risk level to 4. This means enhanced mosquito surveillance will take place at the positive test sites, alongside routine surveys of adult mosquitoes which will be identified and screened for the virus.
West Nile virus, transmitted to humans through the bite of an infected mosquito, can result in serious illness. Residents are urged to take preventive measures:
- Eliminate standing water: Remove potential breeding sites such as old tires, flowerpots, and clogged rain gutters around homes.
- Avoid outdoor activity during peak mosquito hours: Remain indoors at dusk and dawn.
- Dress appropriately: Wear long sleeves and long pants when outdoors.
- Use insect repellent: Apply repellent containing DEET, picaridin, or oil of lemon eucalyptus.
The City is providing a limited supply of Bti briquettes, which kill mosquito larvae. Proof of residency is needed for a limit of two per resident. Pick-up is available at:
- Customer Service, 601 E. Hickory St., Ste F, Monday-Friday, 8 a.m. – 5 p.m.
- City of Denton Composting, 1100 S. Mayhill Rd., Tuesday-Saturday, 7 a.m. – 3 p.m.
While the risk of a human outbreak is moderate to high, those over 50 and with weakened immune systems are more susceptible to severe illnesses. Symptoms of West Nile virus range from fever and headache to severe neurological disorders. Most infected individuals recover without symptoms, but any concerning symptoms should prompt an immediate visit to a healthcare provider.
