Face masks will become compulsory in shops and indoor spaces in Wales from Monday, the First Minister has said.
Mark Drakeford said the country has reached a threshold where 20 people in 100,000 are suffering from coronavirus.
But if the rate falls and Covid-19 is “effectively suppressed”, the Welsh Government will revisit the issue, he said.
Wales will make indoor meetings of more than six people illegal from Monday, though children under the age of 12 will not count towards that total.
Mr Drakeford told BBC Breakfast: “We said that, if coronavirus reached a certain threshold in Wales, we would revisit our advice on face coverings.
“Today, for the first time, we will go to a point where 20 people in 100,000 in Wales are suffering from coronavirus.
“That’s the threshold we use for people to have to quarantine coming back into the UK and, having reached that threshold, today we will be making the use of face coverings mandatory in shops and enclosed public spaces in Wales.
