Coronavirus updates: 84% of California population to go on lockdown Sunday night

Two California regions will have to enact new stay-at-home orders because their intensive care unit capacities have dipped below 15%.

ICU capacity is at 8.6% in San Joaquin Valley and 12.5% in Southern California, the state health department reported on Saturday.

Hair salons, barbershops, museums, bars, playgrounds and more must close based on a new regional stay-at-home order introduced this week. Residents are also instructed to stay home as much as possible.

The order, which goes into effect at midnight Sunday and will last for at least three weeks, impacts 23 counties between the two regions.

The new policy comes as cases continue to surge in California. The state saw a record 25,068 new COVID-19 cases on Friday. There were 209 new deaths, which is approaching an August peak.

 Los Angeles County, a particularly hard-hit region, reported a record 8,949 cases on Saturday.

The number of new COVID-19 cases and deaths are increasing again, following a Thanksgiving data slowdown, an internal Health and Human Services memo obtained by ABC News shows. 

From Nov. 28 to Dec. 4, new cases increased 3.2% and deaths went up 16% compared with the previous week, the memo said.

The national test-positivity rate rose to 12.1% from 10% in week-to-week comparisons.

Across the country, 30% of hospitals have more than 80% of their intensive care unit beds filled, and 29% of ventilators in use are occupied by COVID-19 patients, a slight increase.

In Arizona, ICU bed use increased 458% from Sept. 29 to Dec. 2, according to HHS. As of Dec. 2, California had 1,810 ICU beds available, the lowest capacity during the pandemic. Hospitals in the southwest and southeast regions of Colorado had reached ICU capacity as of Dec. 3, the memo said.

Hospitals in New Mexico may soon move to "crisis standards of care," meaning doctors would ration services based on a patient's likelihood of surviving.

The declaration was likely to come Monday, Gov. Michelle Lynn Lujan Grisham said in an interview with the Washington Post., with each hospital making its own decision about whether to move to the crisis plan.

As of Saturday, New Mexico had reported 104,935 infections and 1,706 deaths from the virus, according to the state health department.

The United States death toll from the coronavirus surpassed 280,000 Saturday afternoon.

At least 280,090 Americans have died from COVID-19, according to the latest data compiled by Johns Hopkins University.

The U.S. surpassed 270,000 deaths on Tuesday.

The seven-day average for daily deaths is 1,949, according to the COVID Tracking Project.

The Centers for Disease Control and Prevention predicted this week that the U.S. death toll from the virus could reach 329,000 by Dec. 26.
