Coronavirus: Expert panel to assess face mask use by public

A panel of advisers to the World Health Organization (WHO) will consider new evidence to determine whether it should change its recommendations on the use of face masks, to help slow the spread of coronavirus.

SPS commentary:

Current advice from WHO is that healthy people only need to wear face masks if they are caring for others suspected of being infected or if they themselves are coughing or sneezing. The BBC report notes that a laboratory study conducted in the US suggests coughs can project liquid up to 6m away, and sneezes 8m away. A spokesperson for Public Health England said there was little evidence of widespread benefit from wearing masks outside clinical settings.
