Covid-19 cases surge

Most of California faces strict new lockdown as cases surge

More than half of the state's 40 million people will be subject to a stay-at-home order, as announced by Governor Gavin Newsom on Thursday.

Many businesses will be closed, and people will be banned from meeting anyone outside their household.

The order was triggered by intensive care capacity in hospitals shrinking.

The southern part of the state and its central valley will be the first areas to come under the new restrictions, at 23:59 local time on Sunday (07:59 GMT on Monday).
