The US has reported its first death from the new coronavirus, in the north-west state of Washington.
Officials said the patient was a man in his 50s with underlying health conditions.
President Donald Trump said more cases were “likely” but that the US was prepared for any circumstance.
Officials said they were expanding travel restrictions on Iran and urged Americans to avoid hard-hit parts of Italy and South Korea.
More than 85,000 coronavirus cases have been reported in 57 countries around the world and almost 3,000 deaths, according to the World Health Organization. The vast majority of infections and deaths are in China, where the virus emerged late last year.
What is happening in the US?
Local health officials confirmed on Saturday that the man in his 50s died in Washington state’s King County. They said he had not travelled to any high-risk areas.
There was confusion earlier as Mr Trump described the patient as a “wonderful woman”.
Washington Governor Jay Inslee has declared a state of emergency in response to new cases in the state.
It comes as officials on the US West Coast – in California, Oregon and Washington – expressed concerns about cases appearing in patients who had not visited an area where there was an outbreak or been in contact with anyone who had.
Officials in Washington state on Saturday said they were investigating a possible outbreak of the coronavirus at a local nursing home.
Dr Jeffrey Duchin, a health official for Washington’s Seattle and King County, said there were two cases associated with the long-term care facility Life Care Center of Kirkland – one a healthcare worker and the other a resident in her 70s.
Dr Duchin said about 27 residents and 25 staff members at the centre had “some sort of symptoms”. Officials said more positive cases were expected.
In total, the WHO says there have been 62 cases in the US so far.
A US citizen previously died in the Chinese city of Wuhan, where the virus first appeared.
What else did Trump say?
While acknowledging that more cases were expected, he also sought to quell fears over the outbreak.
“Since the early stages of the foreign outbreak my administration has taken the most aggressive action in modern history to confront the spread of this disease,” he said.
“Our country is prepared for any circumstance. There is no reason to panic at all.”
He said healthy individuals “should be able to fully recover”.
Vice-President Mike Pence announced that an existing ban on travel from Iran had been expanded to include any foreign national who has visited the country within the last 14 days.
Iran has reported the most coronavirus deaths outside China.
Americans were also urged not to visit hard-hit areas in global hot-spots Italy and South Korea.
Mr Pence said the US was working with local officials to co-ordinate screening of travellers entering the US from those countries.
France tightens restrictions
France earlier announced that it had banned all indoor gatherings of more than 5,000 people, as part of efforts to contain the country’s outbreak.
Measures announced after an emergency cabinet meeting also include the cancellation of the Paris half-marathon which was to be held on Sunday.
In the worst-hit area, north of Paris, all public gatherings have been banned.
The total number of cases of the new coronavirus in France rose to 100 on Saturday. Two patients have died.
“Our goal at this stage is to limit the spread,” Health Minister Olivier Véran said after Saturday’s cabinet meeting.
Among the events affected by the prohibition of large indoor gatherings is Paris’s annual agricultural fair. Its final day, which was scheduled for Sunday, has been cancelled.
