Harris County Public Health officials announced the launch of an online, public dashboard aimed at informing the community about human cases of mosquito-borne diseases.
As of Oct. 16, at least 192 positive mosquito samples across the county have been identified.
Throughout the year, HCPH’s mosquito and vector control department officials track, test, and eliminate disease-carrying mosquitoes in the county, according to an Oct. 17 news release.
The specifics
The interactive dashboard, Mosquito Diseases, provides daily, real-time county maps where mosquito-borne diseases have been identified. The data does not include potential Houston cases, according to the news release.
In 2025, HCPH confirmed West Nile virus in the northern section of the county including parts of Tomball, Spring, Humble, Cypress, Katy and Kingwood.
Jennifer Kiger, director of the county’s office of epidemiology, surveillance and emerging diseases department, said in a news release the new dashboard is for residents to stay informed about potential mosquito-borne diseases in Harris County.
“While our current case numbers are low, it’s still important for everyone to protect themselves from mosquito bites—especially during the warmer months when mosquitoes are most active,” Kiger said.
What residents should know
HCPH said these tips can help the community reduce the risk of mosquito-borne illnesses:
- Tipping standing water from containers around homes
- Tossing out items that can collect rain or irrigation water
- Using insect repellant
- Wearing protective clothing when outdoors
