For instance, wearing a mask reduces risk but doesn’t eliminate it. It is the same with distancing. 6ft may not be sufficient

This latest publication in BMJ, published 25 August 2020, by the University of Oxford has attempted to qualify the risk of SARS-CoV-2 transmission from asymptomatic people in different settings. This guide shows how transmission risk may vary with setting, occupancy level, contact time, and face coverings. This graph is intended to be an initial quick
