Wales has reported its first death and 30 new cases of coronavirus, taking its total to 124.
A 68-year-old man died while receiving treatment in Wrexham.
The latest rise in Wales came as Prime Minister Boris Johnson chaired an emergency Cobra meeting at No10 and prepared to deliver a televised address to the nation as the UK moves towards banning mass gatherings and asking the elderly to stay at home more.
Mr Johnson's chief adviser, Dominic Cummings, said the Government would make further announcements about the measures it is taking to tackle Covid-19.
Children who develop a continuous cough or fever at school should be sent home with suspected coronavirus, new guidance states.

Updated information from the Government says all educational settings should remain open unless directly advised to close by Public Health England.
The Government has so far refused to close schools - a drastic measure taken by a number of European countries, including Ireland, Spain and France, and parts of the US and Canada.
It comes as there was confusion over exactly what elderly people will be asked to do going forward, after Health Secretary Matt Hancock said on Sunday they will be asked to stay at home for a very long time.
On Monday, Transport Secretary Grant Shapps said people over the age of 70 will be asked to self-isolate "as and when the moment is right" - but that they would still be able to go outside and "walk the dog".
He said: "We will ask people to do that as and when the moment is right."
He said it is "quite likely" that elderly people would have to self-isolate for months, but added: "It is the case that people will be able to go out and walk the dog. It's about being sensible, but not mixing in crowds."
But Scotland's national clinical director, Professor Jason Leitch, said elderly people across the UK will not be asked to stay at home.
Downing Street said it does not expect eight million people to be hospitalised because of coronavirus.
Asked about the leaked Public Health England briefing, the Prime Minister's official spokesman told a Westminster briefing: "I think what the documents reflect is the reasonable worst case scenario which we have set out very clearly in the plan we published a week ago now.
"It does not mean that is what we expect to happen... a reasonable worst case scenario is what we are planning for and that is what any responsible government would do. But that does mean that's what we expect to happen."
