Mosquitoes in all four western Mass counties test positive for West Nile virus


During the month of July, the Massachusetts Department of Public Health announced 19 cities and towns in the western Massachusetts have tested positive for West Nile virus.

And now 20 after Greenfield tested positive for the infectious disease on Friday.

Last week, Mass DPH raised the threat level for West Springfield from low to moderate.

The change comes from the recent mosquito pools that have tested positive for the virus in Northampton, Chicopee, and Holyoke.

The Executive Office of Health and Human Services’ website shows a total of 120 positive mosquito samples across the state.

You can reduce your risk of West Nile virus by using insect repellent and wearing long-sleeved shirts and long pants to prevent mosquito bites. And by removing areas of standing water around your home to eliminate sources of mosquito breeding.

To-date no humans or animals have tested positive for West Nile virus in the state.
