HARRIS COUNTY, Texas — Harris County announced Friday that planes will begin aerial spraying for mosquitos this weekend as West Nile virus human cases increase.
Harris County Public Health said there are now 23 human cases of the virus which is more than triple the previously reported total of seven cases. Of those 23 cases, 21 of the patients have been hospitalized but there have been no deaths, according to Harris County Public Health Director Ericka Brown.
The patients ranged in age from 6 to 85 and 15 of them have fully recovered.
While most people infected by West Nile virus experience mild or no symptoms, some get very sick. Symptoms of WNV include fever, headache, body aches, nausea, rash or vomiting.
In severe cases, WNV 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 higher risk of severe complications from WNV.
The 23 cases are outside of the Houston city limits, in the unincorporated areas of Harris County where they've had 615 mosquito samples test positive all across the county.
"We have 180 sections positive for West Nile virus. Those areas we are treating," said Dr. Maximea Vigilant, the Mosquito Vector Control Division director.
As the extremely hot and humid weather continues for Southeast Texas, these mosquito-born illnesses are a concern. The abundant rainfall and high temperatures have created ideal breeding grounds for mosquitoes.
Mosquito Control and Vector Control Division has scheduled aerial spraying for portions of west and northwest Harris County for Saturday evening.
Officials said the plan is to spray approximately 81,640 acres by air, weather permitting, from 8 p.m. to 5 a.m. on Saturday and Sunday. Doctors say you and your pets should stay indoors while the spraying is taking place.
Experts advise residents to protect themselves and their loved ones against mosquito-borne illnesses with the 3D defense.
- DEET: Apply EPA-approved insect repellent with the ingredient DEET.
- Dress: Dress in long sleeves and pants while outdoors to limit exposed skin.
- Drain: Drain standing water around your home so mosquitos don’t have a place to breed.
Anyone who experiences symptoms should immediately contact their healthcare provider.
