Savannah, Georgia, announced Tuesday that it will now require people wear face masks or coverings while in public.
The emergency order will start at 8 a.m. Wednesday and will remain in effect until further notice.
In a statement on the city's Facebook page, Mayor Van Johnson said, "frankly and honestly, I do not believe we have another choice."
Johnson said the city's seven-day average of new cases is 43, which is a new record, and the 14-day rolling average is 33, which is also new record.
Anyone who fails to comply with the order will face a fine.
"The point of this order is not to be punitive," Johnson said. "If we see someone without a face covering, the first thing we will do is offer them one. If that person refuses the face covering, that's a different issue entirely."
