Gavin Newsom first announced on Dec. 3 and was set to expire Monday, splits the state into five regions — the Bay Area, Greater Sacramento, Northern California, San Joaquin Valley and Southern California. If the remaining ICU capacity in a region falls below 15%, it will trigger a three-week stay-at-home order, Newsom said.The order requires bars, wineries, personal services, hair salons and barbershops to temporarily close. Personal services are businesses like nail salons, tattoo parlors and body waxing, according to the state’s website. The order also bans gatherings of any size and requires “100% masking and physical distancing.”As of Tuesday, all but the Northern California region were under the state’s stay-at-home order, Ghaly said. Moving forward, however, both the San Joaquin Valley, which comprises the middle portion of the state, and the Southern California regions will remain under the order, he said.Those two regions will continue to be subject to the restrictions until projections from the state show ICU capacity above or equal to 15%, he said. Ghaly added that projections will be calculated and updated daily moving forward. Just because the San Joaquin Valley and Southern California regions will remain under the order, it doesn’t mean they’ll be there for the full three weeks, he said.According to a slide Ghaly presented at a press briefing, those two regions showed no available ICU capacity. Four-week projections from state health officials have determined that ICU capacity in those two regions is not improving, Ghaly said.”We essentially are projecting that the ICU capacity is not improving in Southern California and San Joaquin Valley, and that demand will continue to exceed capacity,” Ghaly said during a press briefing.
