Masks are now required in all public schools in Passaic, New Jersey.
Starting Wednesday, this mandate will impact students, teachers, and visitors throughout the district.
The superintendent says she will lift the mandate once COVID-19 case numbers drop.
Meanwhile, in New York, officials in Rockland County are also telling people to mask up.
The county says that as of December 16, the infection rate met the CDC criteria for face coverings.
Now, they're recommending people wear a mask indoors and on public transit.
Health officials also want people to stay up to date with vaccinations and get tested if they have COVID symptoms.
