Oklahoma City's City Council extended the city's mask mandate.
In a 7-2 vote, the council voted to extend the mask mandate through April 30.
The masks are mandated indoors in most public places.
Everyone in Oklahoma City age 11 and up is required to wear a face covering, like a mask or face shield in indoor public spaces.
"Our predicted model shows if the mask ordinance stays in place and residents continue social distancing and washing their hands, we could achieve herd immunity by June,” said Phil Maytubby, chief operating officer for the Oklahoma City-County Health Department. “Scientific data shows mask wearing is highly effective.”
