Earlier this week, the government changed their stance on wearing face coverings during the coronavirus pandemic in the UK.
Until this point they had said there was no need for the general public to wear them when out and about. But as of Wednesday (May 12) this is no longer the case.
The new advice is that people should "consider wearing face coverings in enclosed public spaces where you may be more likely to come into contact with people you do not normally meet".
According to the experts, enclosed public spaces include public transport such as buses and trains, as well shops. So if you can wear a face covering, you should try and wear one in these places to help limit the spread of the virus.
