First Animal Case Of West Nile Virus In MA For 2025

LUNENBURG, MA — State officials have confirmed the first animal case of the West Nile Virus in Massachusetts this year. A goat was exposed to the virus in Lunenberg, according to a news release from the Massachusetts Department of Health.

The DPH said that the towns of Lunenburg, Leominster, Shirley and Fitchburg are being raised to moderate risk.

“With this evidence of an animal infected with West Nile virus, we know that there are the right conditions and enough disease circulating to result in a human infection,” said Robbie Goldstein, Public Health Commissioner.

Elevated temperatures and high humidity increase mosquito activity, said Goldstein.

Right now, there have been no human cases of the virus detected. Last year, there were 19 human cases and no animal cases, according to the DPH. Most people infected will have no symptoms, but people over 50 years old are at higher risk.

The DPH recommends avoiding mosquito bites. You can do this by being aware of peak mosquito hours, wearing clothing that can help reduce bites and applying insect repellent when outdoors.

The DPH also recommends mosquito-proofing your home by draining standing water or installing screens. Also, the department is urging residents to protect their animals.
