The ninth reported case in Hunt County comes as officials across the region are stepping up efforts to quell the spread of the virus, which has led to 10 deaths in Dallas County.
Aerial spraying in the Metroplex will commence Thursday night. Meanwhile, some local cities have been working the problem for much of the summer.
Commerce Public Works Foreman Daryl Martin has been spraying for the city the last 10 years. His route covers the four sections of town over a four day period, and then is repeated every other week.
"I got a control switch in my truck so I can activate the machine inside my truck - cut it on and off whenever I have to - when people are around," Martin said.
The Texas Division of Emergency Management on Wednesday also reported cases of West Nile virus Fannin, Kaufman, Lamar and Van Zandt counties.
On Friday's edition of The Lead, we speak more with Martin during a mosquito spraying ride along, and further examine the growing number of West Nile cases in our region, plus the chemical used to control the mosquito population.
