The public is advised to 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, the government announced today.

When should I wear a mask/cover my face?

They may be beneficial in places where it is hard to follow maintain social distancing measures. This applies when using public transport, such as trains, buses and metro systems, or when visiting shops.

What about wearing them generally?

They do not need to be worn outdoors, while exercising, in schools, in workplaces such as offices and retail, by those who may find them difficult to wear, such as children under two or primary aged children who cannot use them without assistance, or those who may have problems breathing while wearing a face covering.

What kind of mask do I need?

The public is being strongly urged not to purchase surgical masks or respirators. These are prioritised for healthcare workers working in more high-risk environments where the risk is greatest.
Instead the public is encouraged to make face coverings at home, using scarves or other textile items that many will already own.

The Government has issued helpful advice on how to make your own mask instead:
