Do Face Masks Work asks the New Scientist Magazine!

As cases of covid-19 continue to rise, many people are choosing to wear a face mask when out in public – but do they work?

Guidance on face masks varies wildly among international health bodies and governments. The World Health Organization (WHO) currently only recommends face masks for people who are coughing or sneezing, or for those who are caring for people who are suspected to have covid-19.
