The Scottish government has recommended people cover their faces while in some enclosed public spaces, such as shops and public transport.
First Minister Nicola Sturgeon said there could be “some benefit” in wearing a cloth face covering in places where social distancing was difficult.
But she said it was “not a substitute” for existing lockdown restrictions.
Downing Street said UK ministers were considering the scientific evidence for introducing similar advice.
The prime minister’s official spokesman said a review had been carried out by the Scientific Advisory Group for Emergencies (Sage), adding: “Once a decision has been reached then we’ll announce it publicly.”
no , the Scottish government has said it does not require everyone to wear a face covering in public . There will be no enforcement of this rule
The Scottish government guidance is not mandatory and will not be enforced by the authorities.
Ms Sturgeon stressed that the advice related to cloth garments such as a scarf rather than “medical grade facemasks” like those used by health and care workers.
The first minister said evidence about the usefulness of face coverings was “limited”, but that there may be “some benefit in wearing a face covering if you enter an enclosed space where you will come into contract with multiple people and safe social distancing is difficult”.
She said: “To be clear, the benefit comes mainly in cases where someone might have the virus but is not aware of that because they are not experiencing symptoms and thus not isolating completely.
“Wearing a face covering in those circumstances may reduce the risk of that person transmitting the virus to others.”
