Scotland First Minister Nicola Sturgeon says schools have now lost too many staff to continue as normal. Per the Daily Express, Sturgeon said: "These measures are about protecting the population as a whole and safeguarding our NHS."
It is not known when Scotland's school will reopen.
Northern Ireland has taken the decision to close all its schools as of 17:00 GMT today (Wednesday).
Liberal Democrat education spokesperson Layla Moran MP spoke to Sky News about the "consequences" of closing schools, saying: "Looking at the modeling that was released yesterday it does seem like it is almost going to become an inevitability but it makes it very clear in those models that there are other consequences to closing schools.
"While on the one hand, we worry about the students who are about to take their exams. Will schools have the resources to be able to do online teaching?
"What about the vulnerable students who rely on schools for free school meals? The other impact is on the NHS workers who rely on schools to be able to look after children.
"In my view, I think we have now come to the point where we would rather be safe than sorry. I would certainly support closing schools and universities so long as we have taken the time to plan."
