Currently, testing in 2018 has resulted in one (1) positive trap for West Nile Virus.

WNV positive test resulted on 9/12/18 in CH2 management area. Spray scheduled for CH2 management area on 9/13/18 and 9/14/18 from 9 pm to 5 pm depending on weather.

Surveillance & Testing Program

The City of Cedar Hill partners with Dallas County Health and Human Service (DCHHS) to conduct the West Nile Virus surveillance and testing program. Each week, mosquito traps are set, collected and tested in mosquito management areas (MMA). Mosquitoes are tested for West Nile Virus (WNV).

When a "pool" of mosquitoes tests positive for WNV, DCHHS schedules vector control spraying in the MMA where the positive sample was trapped. The spraying takes place at night from a truck mounted sprayer.

The City of Cedar Hill conducts mosquito control activities year-round but increases those efforts from April through October, the most active mosquito season in North Texas. The City coordinates with Dallas County Health and Human Services (DCHHS) to conduct surveillance, trapping and testing of the mosquito population for diseases including West Nile Virus (WNV). 

There are currently five Mosquito Management Areas in Cedar Hill where mosquitoes are trapped weekly and then taken to a Dallas County lab for testing. If a mosquito trap yields a positive result for West Nile Virus, Dallas County Mosquito Control will schedule an overnight spraying event in the affected management area beginning Sunday night.
