These are the types of face masks you can use - and how effective they are

Whether the public should wear face masks or not to prevent the spread of coronavirus is an issue that has come under much debate.

At present, the World Health Organisation (WHO) is currently only advising those who are sick and showing symptoms of the virus to wear a mask, such as coughing or sneezing, or if you are caring for someone with a suspected coronavirus infection.

Aside from this, masks have only been deemed necessary for use in a medical setting, but now experts are recommending the public should wear homemade masks when they venture outdoors.

Is the UK changing its guidance on face masks?

Experts from the Scientific Advisory Group on Emergencies (Sage) met on Thursday (23 Apr) to debate the issue and have now finalised their advice, Downing Street has confirmed.

The Prime Minister’s official spokesman said the Cabinet was told that the recommendations from Sage have now been submitted for ministers to consider.

Scientists have passed on research showing that coverings could help to stop asymptomatic people from passing on the virus, and claimed the UK’s current policy on masks does too little to prevent infections.

While experts believe that face masks won’t prevent people from catching the virus, they could help in preventing it being spread to others.

A decision based on the advice is yet to be announced by the government.

The PM’s spokesman said: "They have finalised their advice. Ministers will now be reviewing this to decide on any further action that might be needed.”
