Towns in Massachusetts are being told to stay indoors at night due to fears of a deadly mosquito virus being spread. The viral disease, eastern equine encephalitis, was first detected in a man in his 80s in 2020. Now an Oxford man, over 50 miles from west of Boston , and a horse in the historical town of Plymouth, about 40 miles southeast of Boston , contracted the disease, state health officials announced Friday.

The spread coincides with warnings about West Nile virus, which is also transmitted via mosquito bites . The town known for hosting the first settlement of the 246-year-old country has issued a curfew for public outdoor recreational facilities from dusk until dawn each evening. Four other towns have also urged people to avoid going outside at night.
