Covid: What's the science when it comes to schools?
The decision to keep schools closed has hit both pupils and parents across Wales.
Most children will now be out of the classroom and learning from home until at least February half-term, unless there is a big drop in Covid cases.
The Welsh Government's decisions on coronavirus are assisted by its Technical Advisory Cell (TAC), a group of experts who assess all the latest scientific advice
on the virus.
So what exactly is the latest science when it comes to schools?
Dr Heather Payne, a consultant paediatrician and a member of TAC, describes her role as helping to get together the "best advice" to inform ministers making
decisions. Here she answers some questions.
What's changed in the past couple of weeks?
"I think the most important thing is that the overall rates of coronavirus infection were going up. We know now that was due to this new variant," explained
Dr Payne.
"It is coronavirus but it's much more infectious than the original one that we were dealing with last year. That in itself led to changing our advice around
the operation of schools."
"Now it might be tempting to think that children are spreading it in schools," she said.
"But when we break down the data we find that actually schools are safe, secure environments for children."
However, Dr Payne acknowledged that keeping schools open had meant there were more opportunities for "social mixing," which may help the virus spread,
such as walking to and from school, or attending after-school activities.
Where in schools is transmission happening?
Dr Payne said, despite efforts, scientists were still unable to say for certain where in school environments coronavirus might be passed on.
"I think the problem is that we really don't know, we've asked this question to some of the best scientists in the country," she said.
"Even the head of the Office of National Statistics agrees that we just don't have the evidence of where, during the school day, from leaving the house in
the morning to getting back in the evening, transmission really takes place."
However, Dr Payne said some areas were riskier than others.
