The West Nile virus has been detected in mosquito samples in Natick, according to the Massachusetts Department of Public Health.
The virus can be spread to humans and animals via the bite of an infected mosquito, and according to the Centers for Disease Control, about 1 in 5 people infected develop a fever. Far fewer get a serious illness.
The risk of infection is still considered low in Natick, according to the state. Last year, Natick had no positive West Nile virus samples.
Residents are encouraged to take common sense precautions, including using spray if outdoors between dusk and dawn.
Natick coordinated with the Central Massachusetts Mosquito Control Project to spray a designated area after sunset on Wednesday, Aug. 24. Residents can opt out of future spraying at their properties.
