West Nile Virus

OCT. 1, 2021

The Garland Health Department (GHD) received a report of laboratory confirmed presence of West Nile Virus (WNV) in mosquitoes collected in the 1000 block of Bay Shore Dr. (GA16). GHD will immediately initiate adulticide spraying throughout the surrounding area on Oct.1, weather permitting and again on Oct. 4, 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.
