At the peak, the medical center was treating more than 200 patients with COVID-19, according to a hospital statement.

San Bernardino County is currently in the orange tier of California's reopening framework.
The region currently has two out of the three criteria for moving to the least-restrictive yellow tier.

The county needs to get that number below two for two straight weeks to move into the yellow tier.
