Harris County officials announced on Friday that aerial spraying for mosquitos will commence this weekend due to a significant rise in human cases of West Nile virus. The Harris County Public Health Department reported that the number of cases has surged to 23, more than triple the previously reported total of seven. Among these cases, 21 patients have been hospitalized, though no deaths have occurred, according to Harris County Public Health Director Ericka Brown.
The patients, who range in age from 6 to 85, include 15 who have fully recovered. While most people infected with West Nile virus (WNV) experience mild or no symptoms, some may become seriously ill. Symptoms of WNV can include fever, headache, body aches, nausea, rash, or vomiting. In severe cases, the virus can lead to encephalitis (inflammation of the brain) and meningitis (inflammation of the lining of the brain and spinal cord). Older adults and individuals with weakened immune systems are at a higher risk of severe complications from WNV.
The 23 cases have been identified outside of the Houston city limits, in unincorporated areas of Harris County, where 615 mosquito samples have tested positive across the county. Dr. Maximea Vigilant, Director of the Mosquito Vector Control Division, noted that 180 sections of the county have tested positive for West Nile virus and are being treated accordingly.
With the continuation of extremely hot and humid weather in Southeast Texas, mosquito-borne illnesses remain a pressing concern. The combination of abundant rainfall and high temperatures has created ideal breeding conditions for mosquitoes.
The Mosquito and Vector Control Division has scheduled aerial spraying for parts of west and northwest Harris County on Saturday evening. Weather permitting, the plan is to spray approximately 81,640 acres between 8 p.m. and 5 a.m. on Saturday and Sunday. Residents and their pets are advised to stay indoors during the spraying.
Experts recommend residents use the 3D defense to protect against mosquito-borne illnesses:
- DEET: Apply EPA-approved insect repellent containing DEET.
- Dress: Wear long sleeves and pants while outdoors to minimize exposed skin.
- Drain: Eliminate standing water around homes to prevent mosquito breeding.
Anyone experiencing symptoms of West Nile virus should contact their healthcare provider immediately.
