The Massachusetts Department of Public Health confirmed Thursday the presence of West Nile Virus in mosquitoes collected in South Brookline near the West Roxbury line.
The discovery of the virus indicates that it may be present in mosquitoes throughout the town, according to an alert issued by Brookline’s Public Health Department Thursday advising residents to take precautions to avoid mosquito bites.
The mosquito-borne virus can cause encephalitis, or swelling of the brain, and residents are at the highest risk of getting the disease in late July through the fall.
The town will be applying larvicide to targeted catch basins and some wetland areas to prevent hatching of new mosquitoes. Spraying to kill adult mosquitoes may be done, but only if absolutely necessary and if it is recommended by the state, according to the town.
Residents can also contact the town for more information at 617-730-2295.
