The number of coronavirus cases in the UK has now reached 163, the government has confirmed.
It is a jump of 48 cases since Thursday – the biggest increase in one day. More than 20,000 people have been tested.
Meanwhile, samples taken from an elderly man who died at Milton Keynes Hospital are currently being investigated for coronavirus.
The BBC understands the man, in his 80s, had underlying health issues but more tests for the virus are ongoing.
The UK’s first death linked to the virus came on Thursday, after a woman with underlying health conditions in her 70s died in hospital in Reading.
As well as her death in the UK, a British man also died from the virus last month after being infected on the Diamond Princess cruise ship off the coast of Japan.
The Department of Health said as of 9:00 GMT on Friday, 20,338 people had been tested.
The latest number of confirmed cases comprises 147 cases in England, 11 in Scotland, three in Northern Ireland and two in Wales.
Of the cases in England there are:
In Scotland, there are three cases in Grampian, two in Fife, two in Forth Valley and one each in Lothian, Tayside, Ayrshire & Arran and Greater Glasgow & Clyde.
About 45 of the confirmed cases have been self-isolating at home, while 18 people have recovered.
Earlier, the UK government pledged to spend £46m on urgent work to tackle the coronavirus – including more money to develop a vaccine and cash to help some of the most vulnerable countries prepare for an outbreak.
The money will fund work on eight possible vaccines which are already in development as well as a lab in Bedford to try to create a test that could provide results within 20 minutes.
Currently, tests take a couple of days to provide results.
In other developments:
On Thursday, Health Secretary Matt Hancock told a BBC Question Time audience he was “absolutely confident” food supplies would not run out, amid concerns some people were stockpiling.
But a supermarket executive told the BBC sales of cupboard basics had “gone through the roof” and he was not sure the government could guarantee food supply in all instances.
Meanwhile, the prime minister’s official spokesman previously said it was “highly likely the virus is going to spread in a significant way”.
The government said the UK was still in the first phase of its four-part plan to tackle the virus outbreak, which is made up of: contain, delay, research and mitigate.
But officials were ramping up work to prepare for the next phase, the PM’s spokesman added.
The government is still deciding what measures will be taken in the delay phase, but has previously said this could include banning big events, closing schools, encouraging people to work from home and discouraging the use of public transport.
Earlier this week, the country’s chief medical adviser Prof Whitty said half of all coronavirus cases in the UK are most likely to occur in just a three-week period, with 95% of them over a nine-week period.
Globally, the number of coronavirus cases has now passed 100,000, with 3,400 deaths.
The government has updated its advice for Italy – the country in Europe that has been hit worst by the virus, with more than 3,000 cases.
Travellers who develop symptoms after returning from any part of Italy – not just the north of the country – should self-isolate, while those returning from quarantined areas should self-isolate even without symptoms.
