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

Just one day after California recorded its highest daily case count ever -- 25,000 cases in a single day and nearly 9,000 cases in Los Angeles County alone -- 33 million residents in the state are returning to some of the strictest lockdown procedures since the start of the pandemic.

The restrictions begin at midnight local time.

The lockdown comes as health officials have warned if there is not a significant change in the rise in cases, hospitals in the state could be out of available beds by Christmas.

In hard-hit Imperial County, there are only two ICU beds remaining, according to county data. In Los Angeles County, the number of hospitalized COVID-19 patients has increased 106% in the past three days.

Los Angeles Mayor Eric Garcetti said on Friday, "8860 cases, a number I can hardly believe, that just a few weeks ago would have been unimaginable. We're on the verge of reaching 10,000 cases daily with the numbers that we're seeing this week."

As part of the lockdown, gatherings of people from different households will be prohibited, except for outdoor services and political demonstrations.

All outdoor dining must immediately close, hair and nail salons, playgrounds, zoos, museums, aquariums and wineries must also be closed.

Nonessential travel is banned and stays at campgrounds, overnight or short-term, will not be permitted. Retail can remain open, but only at 20% capacity.

The National Health Service (NHS) in the United Kingdom has announced that it will begin vaccinating patients against coronavirus at dozens of hospital hubs starting on Tuesday, Dec. 8.

In what will be the biggest immunization program in British history, the first people who are eligible for the initial roll out of the vaccine are people aged 80 and over as well as care home workers will be first to receive the jab, along with NHS workers who are at higher risk, the NHS said in a statement.

“This coming week will be an historic moment as we begin vaccination against COVID-19," Health Secretary Matt Hancock said. "We are prioritizing the most vulnerable first and over-80s, care home staff and NHS colleagues will all be among the first to receive the vaccines. We are doing everything we can to make sure we can overcome significant challenges to vaccinate care home residents as soon as possible too. I urge everybody to play their part to suppress this virus and follow the local restrictions to protect the NHS while they carry out this crucial work.”

The NHS said that there are 50 hubs in the first wave and more hospitals will start vaccinating over the coming weeks and months as the program ramps up.

“Despite the huge complexities, hospitals will kickstart the first phase of the largest scale vaccination campaign in our country’s history from Tuesday," said Professor Stephen Powis, the NHS national medical director. "The first tranche of vaccine deliveries will be landing at hospitals by Monday in readiness. The NHS has a strong record of delivering large scale vaccination programs – from the flu jab, HPV vaccine and lifesaving MMR jabs – hardworking staff will once again rise to the challenge to protect the most vulnerable people from this awful disease.”

The seven-day average for reported COVID-19 deaths in the U.S. is the highest it's ever been, according to The COVID Tracking Project.

The number -- 2,123 -- surpasses the previous record of 2,116, from April 21. 

"Given data drops and spikes on and after Thanksgiving, the 7-average is an especially useful metric to watch right now," the tracker said. 

According to The COVID Tracking Project, the U.S. reported 211,073 new COVID-19 cases and 2,445 deaths on Saturday. There are 101,190 people currently hospitalized with the virus.
