Covid-19: Welsh Government update - BBC News
Details and reaction to a briefing by Wales' chief medical officer and the head of NHS Wales.
Lockdowns have worked before, but can we expect the new one to do the same?

It feels like we are back in March or April last year, when the strict controls on all our lives led to a fairly quick decline in levels of coronavirus.

But one of the crucial differences this time is the new variant, which is thought to spread between 50 and 70% faster than previous forms of the virus.

Experts warn there are now no guarantees that lockdown will be enough to bring the variant under control.

"It still would not have been easy, but it would have been a much easier situation if it had not been for the new variant," Prof Neil Ferguson, from Imperial College London, told Inside Health.

"That really pushes the bounds of our ability to control the spread of the virus, even with measures that were previously relatively quite effective."
