West Nile Virus

JULY 28, 2021

The Garland Health Department (GHD) received a report of laboratory confirmed presence of West Nile Virus (WNV) in mosquitoes collected in the 1600 block of Dent St. (GA15). GHD will immediately initiate adulticide spraying throughout the surrounding area on the nights of July 28 and 29, weather permitting, to minimize the risk of human infections. Spraying will be conducted between the hours of 9 p.m. and 6 a.m.

Thus far in 2021, no WNV human cases have been confirmed in the City of Garland but the presence of the disease in mosquitoes means that transmission to humans is possible, so residents are urged to take preventative measures. 


Positive 2021 WNV+ mosquito trap locations are as follows:

  • 1600 block of Dent St. (GA15), 7/27/21

The Garland Health Department (GHD) is currently trapping at 27 selected locations per week.
