Wear masks in public says WHO, in update of Covid-19 advice

The World Health Organization (WHO) updated its guidance on Friday to recommend that governments ask everyone to wear fabric face masks in public areas where there is a risk of transmission of Covid-19 to help reduce the spread of the pandemic disease.

In its new guidance, prompted by evidence from studies conducted in recent weeks, the WHO stressed that face masks were only one of a range of tools that can reduce the risk of viral transmission, and should not give a false sense of protection.
