Face coverings could reduce the spread of Covid-19, according to a new study by the University of Edinburgh.
Research has found that wearing a face covering can reduce the forward distance of an exhaled breath by more than 90%.
As the breath could contain small droplets of water, some of which may contain traces of the virus, experts have said that covering up the mouth and nose could help combat Covid-19.
Scientists testing the effectiveness of seven different types of face coverings, including medical grade and home made masks, say they could all potentially limit the spread of coronavirus.
