The Grayson County Health Department confirmed a positive test for the West Nile virus in local mosquito populations in a report issued on Thursday. This is the second positive test for the virus this year after a sample taken on Burrell Street in Denison came back positive last month.


On Aug. 26, four mosquito samples were taken in Grayson County. The Texas A&M Veterinary Medical Diagnostic Laboratory reported that one sample, taken in the 1700 block of W. Fannin Street in Denison, tested positive for West Nile Virus.


Since May, 26 traps have been set throughout the county to monitor the presence of the virus. Since Aug. 26, 19 more samples have been taken, but results are still pending.


Amanda Ortez, director of the GCHD, said residents can help prevent the spread of the virus by practicing the the four D’s: Dress appropriately with arms and legs covered, drain standing water near your home or business, use repellents containing DEET, and limit activity during dusk and dawn, when mosquitoes are most active.


"We continue to encourage individuals to remain vigilant and take the necessary precautions to protect themselves and others against the West Nile Virus," said Ortez.


The Department said it will continue to survey the situation and take more samples in areas surrounding the site of the positive sample.
