Mask-wearing is the single most effective public health measure at tackling Covid-19, according to a study undertaken by researchers at Monash University in Melbourne and the University of Edinburgh in Scotland.
The findings, which were published in the British Journal of Medicine, showed that in more than 30 studies analyzed from around the world, there was a 53-percent reduction in the incidence of Covid-19 with mask wearing and a 25-percent reduction with physical distancing.
