Face masks may reduce COVID-19 spread by 85%, WHO-backed study suggests

Social distancing, face masks and eye protection all appear to reduce the spread of COVID-19, in both health care settings and the general community, according to a new review commissioned by the World Health Organization (WHO). 

The review found that keeping a distance of at least 3 feet (1 meter) from other people lowered the chances of coronavirus infection or spread by 82%, and keeping a distance of 6 feet (2 m) could be even more effective.
