"Newly reported cases have stabilized in recent days," Alameda County Health Officer Dr. Nicholas Moss said.
His words come just a day after California Gov. Gavin Newsom lifted the state-imposed stay-at-home order, sending Alameda County and the Bay Area, back to the purple tier in the state's Blueprint for a Safer Economy.
The purple tier is the most restrictive tier for economic activity, but it allows more activities than the stay-at-home order the region had been under.
Moss said Tuesday that he's in agreement that Alameda County should be in the purple tier. He was also optimistic.
"We have the potential to move to the red tier in a matter of weeks," he said.
