The WHO has upgraded the global risk from the coronavirus from "high" to "very high", saying the continued increase in cases and countries affected was "clearly of concern".
The advice from the WHO has not changed, however.
World Health Organization officials are giving their daily press briefing. WHO chief Dr TedrosAdhanom Ghebreyesus started by saying more than 20 vaccines were currently being developed against the new coronavirus - with the first results of tests expected in the next few weeks.
Acting White House Chief of Staff Mick Mulvaney has accused the media of stoking a coronavirus panic because they hope it will "take down" President Trump.
"We took extraordinary steps four or five weeks ago. Why didn't we hear about it? What was going on four or five weeks ago? Impeachment. And that's all the press wanted to talk about," he told a gathering of conservatives on Friday.
He said the press covered impeachment - which saw Mr Trump acquitted earlier in February - because they thought "it would bring down the president".
"The reason they are paying so much attention to it today is that they think this is going to bring down the president, that's what this is all about," he continued.
His advice for the markets, which have been tanking worldwide over virus fears: "Turn off your televisions for 24 hours."
The GMB union has warned that workers in the gig economy could be at a disadvantage if they have to self-isolate.
Mick Rix, GMB national officer, said: "The threat of coronavirus is a huge problem for employers and worker across the UK.
"But workers in the so-called gig economy, or on zero-hours contracts, are left abandoned and penniless if they have to self-isolate.
"Once again the bogus self-employment model is screwing over the disadvantaged.
"GMB is calling on all employers - regardless of the contract– to do the right thing and pay their workers if they have to take time off due to the global health crisis."

UK Prime Minister Boris Johnson has been criticised after it was announced the government's emergency committee would meet to discuss the coronavirus outbreak on Monday.
Downing Street said the committee - known as Cobra - would discuss Britain's preparedness following a sharp increases in cases in mainland Europe.
But opposition politicians have said Mr Johnson should hold a Cobra meeting much sooner.
Jonathan Ashworth, the shadow health secretary, said: "It shouldn't take another three days for this meeting to take place."

Image source, Getty ImagesThere is no evidence the new coronavirus can infect pets, despite reports that a Hong Kong Pomeranian pooch had a ‘weak positive’ test.
It is likely that the virus was simply present on the animal (the way it could be on a door handle or a keyboard), without actually infecting it.
In someone who is infected by the virus, it is replicating in the body – a very different thing to a surface being contaminated by the virus.
With an infected owner, experts say the sample taken from the dog was probably contaminated.
Like many other viruses, such as Ebola and Sars, we know this new virus originated in animals, probably bats, and crossed over to humans over time via another type of wildlife sold in markets.
The growing proximity between humans and wild animals, including encroachment into their natural habitats, is thought to be behind the rise in new viruses not seen in humans before.
But scientists say the likelihood of it making yet another jump to another species (dogs) in such a short space of time is very, very small.
Government workers deployed by the US Department of Health and Human Services (HHS) to help a flight of Americans evacuated from Wuhan were "not properly trained or equipped to operate in a public health emergency situation", according to an anonymous whistleblower within the agency.
The plane arrived in California on 29 January.
The team of more than a dozen HHS workers had face-to-face contact with around 200 evacuees, but were allowed to come and go from the quarantine zone and were not given adequate protective equipment, the whistblower said.
The anonymous complaint was first reported by the Washington Post. It was made by a senior worker, according to whistleblower's lawyer. The lawyer is seeking federal whistleblower protection, arguing that his client has faced retaliation from superiors for reporting the concerns.
On Thursday, HHS Secretary Alex Azar said he was not "aware of any violation of quarantine or, or isolation protocols".
US stocks tumbled in opening trading amid investor fears over the coronavirus.

One show at Paris Fashion Week proved to be unintentionally timely as models wore a range of outfits complete with matching facemasks.
The outfits were shown earlier this week by French designer Marine Serre.
The catwalk show took place amid rising concern about the outbreak of coronavirus, which caused markets to fall around the world on Friday.
But Serre's collection was designed before the outbreak, and she has used facemasks in her collections before.

We told you earlier that confirmed cases of the coronavirus in Iran have jumped to 388, with 34 deaths. The map below shows where all those cases have been reported.
Among those infected are some of the country's top officials, including Masoumeh Ebtekar - the government's highest-ranking woman.
Iran has been accused of understating the true extent of the virus's spread. It denies the allegation and says it has arrested "rumour-mongers" in the country.
The spread of the virus is causing problems for 44 women in the Netherlands called Corona.
“It’s a real shame. My name’s been rather ruined. Suddenly I don’t like it any more,” Corona Willekes, 57, told Dutch broadcaster RTL Nieuws.

Lebanon has barred entry to all non-residents travelling by air, sea or land from countries worst hit by the coronavirus.

Japan's health ministry has confirmed the reports that a British man who tested positive for the coronavirus after travelling on the Diamond Princess cruise ship has died.
He is the first Briton and sixth Diamond Princess passenger to have died from Covid-19 - the disease caused by the coronavirus.
British officials have not yet confirmed the death, with Health Minister Jo Churchill telling the BBC only that she was aware of a British man who was "very poorly".
Dozens of British nationals were on board the Diamond Princess cruise liner when it was quarantined on 5 February, after a man who disembarked in Hong Kong was found to have the virus.
Some Britons on board were flown back to the UK after more than two weeks of quarantine on the ship, but those who had tested positive remained in Japan for treatment.
Mexico, a country of 116 million people, has confirmed its first coronavirus case.
The government previously said it was reviewing a suspected case in a 35-year-old man who had recently been in northern Italy.
Confirmation of the infection followed a second round of tests.
Brazil is the only other country in Latin America to have reported a case of the virus so far - that patient had also recently been to Italy.
