UMass Boston still recommends people wear masks indoors, but says that effective today, it's no longer a requirement.

The Columbia Point school had announced the return of a masking requirement as the area Covid-19 rate was rising.

But the rate has moved to a "medium" level of Covid-19 transmission, based on federal data and there has been a drop in Covid data in Boston's wastewater over the last several days.

"As such, we are lifting UMass Boston’s indoor mask requirement, effective Wednesday, January 18," a campus memo said. "Masks continue to be strongly recommended while indoors on campus, but they are no longer required except while in University Health Services and for those who are unvaccinated. Anyone completing isolation or quarantine should continue to wear masks for the full 10 days, according to existing protocols."
