The Massachusetts Department of Public Health reported on Tuesday, July 23 that West Nile virus has been detected in mosquitoes collected from Dartmouth for the first time this year, the Dartmouth Board of Health announced.

The mosquitos carrying the virus were collected in the Northeast section of Dartmouth. However, this does not diminish the likelihood of the virus’ presence in mosquitos in other parts of town, the board said.

This virus is commonly transmitted to humans through the bite of an infected mosquito. Infected mosquitoes are common throughout the state and are found in urban as well as more rural areas. The virus can infect people of all ages, but people over the age of 50 are at higher risk for severe infection.

The board recommends residents take precautions to protect themselves and others:

Avoid Mosquito Bites 

Apply insect repellent when going outdoors, but be aware certain chemicals can be harmful to young children. The board named DEET, permethrin, picaridin and oil of lemon eucalyptus as ingredients that children should avoid or have specific instructions to be followed.

Though the heat can make it tricky, cover up with clothing whenever possible.

The board also recommends people are aware of peak mosquito hours, which are from dusk to dawn, and avoid being outside during those times or taking extra precautions.

Mosquito-Proof Homes

Draining standing water, which is where many mosquitoes lay their eggs, limits the growth of mosquitoes in the area of a home. The board highlighted rain gutters, drains, unused flowerpots and wading pools as places to check. Installing or repairing screens can also help keep the mosquitoes outdoors.

Fact sheets on ways to discourage mosquitoes and protect public health are available at the town of Dartmouth website under the Board of Health website at https://madartmouth.civicplus.com/640/Mosquito-Information.
