we are told.But to what extent does a cloth mask also protect you from the novel coronavirus? The evidence is a lot less clear, experts tell Global News.“Mostly, cloth masks are not great at protecting the wearer,” says the University of Toronto’s Colin Furness.On the one hand, a mask easily traps the large droplets we exhale that might infect other people.
On the other hand, what others exhale is a fine aerosol of smaller particles that can find their way through and around mask fabric that might infect us.“You will keep your big droplets to yourself, but you will fairly readily inhale the smaller droplets of others,” Furness says.Some masks are better than others, he says.
