California is to begin a night-time curfew on Saturday, in an attempt to curb a surge in coronavirus cases.
The state’s latest figures are now worse than the previous peak in August, the Los Angeles Times reports.
Across the US, the daily death toll linked to Covid-19 has passed 2,000 for the first time since May.
About 187,000 new cases were recorded nationwide in the latest figures – released on Friday for the previous day – which is an all-time high.
Several states have imposed new mask mandates and restrictions to try to combat the rise.
The Centers for Disease Control and Prevention (CDC) has also urged Americans to avoid travelling for the Thanksgiving holiday next week to prevent increased transmissions.
Thanksgiving typically heralds the busiest week for travel in the US. Last year, an estimated 26 million people passed through the country’s airports in the week surrounding the holiday.
What is going on in California?
California reported a total of one million cases last week, making it the second state to do so after Texas.
The new daily curfew, from 22:00 until 5:00, begins on Saturday night and will carry on until 21 December, with a possible extension if needed, according to authorities.
Restaurants will be able to offer takeout and delivery outside these hours.
The stay-at-home order affects 41 out of California’s 58 counties, covering more than 94% of the state’s population.
Some counties have also warned that a more severe lockdown could follow. The latest measures are not as strict as restrictions imposed between March and May, when all nonessential business and travel was prohibited.
Other places, including New York City, are also operating a night-time curfew. Bars, restaurants and gyms are allowed to open until 22:00, but schools have been closed.
The Californian curfew was announced by Governor Gavin Newsom on Friday. “The virus is spreading at a pace we haven’t seen since the start of this pandemic, and the next several days and weeks will be critical to stop the surge,” he wrote in a statement.
Hospital admissions are up 61% statewide in the last two weeks, according to the Los Angeles Times newspaper.
“The data looks really bad right now,” said Los Angeles County Public Health Director Barbara Ferrer on Friday.
Mr Newsom came under criticism last week when it was revealed that he broke his own rules with a 12-person dinner party at a restaurant earlier in the month.
Californian rules permit no more than three separate households to meet outdoors. However, a photo shared by a nearby diner showed showed top lobbyists at the same table as the governor.
Mr Newsom has since apologised, calling his attendance “a bad mistake”.
Is Thanksgiving travel banned?
The CDC has recommended that Americans “consider” avoiding Thanksgiving travel and gatherings.
“It’s not a requirement. It’s a recommendation,” said Dr Henry Walke, the CDC’s Covid-19 incident manager, on Thursday.
The following day, President Donald Trump retweeted the words of Republican Congressman Jim Jordan: “Don’t lockdown the country. Don’t impose curfews. Don’t close schools. Let Americans decide for themselves. And celebrate Thanksgiving.”
The president and President-elect Joe Biden have both said they are against imposing a national lockdown, and favour letting states come up with their own rules.
On Thursday, the White House coronavirus task force had its first public briefing in months. Members, including Vice-President Mike Pence, noted the rise in coronavirus cases .
The task force said indoor gatherings should be limited over the next couple of weeks.
However on Saturday, US media noted that Mr Pence’s wife, Karen, had sent out an invitation for a “Christmas craft” get-together at their home on 9 December for Congressional Club members.
The White House has also so far declined to engage with Joe Biden and his incoming administration on policy, as President Donald Trump refuses to concede the presidential contest.
