Masks do one thing only, which is to prevent droplets from coughs, sneezes or speech from being projected forward. Viruses pass with ease from the inside to the outside surface of the mask. If you are infected, that is likely to have happened within minutes of your donning the mask. Hands up all those who have never touched the front of their mask. Gosh, you even have to do that to bend the metal nose clip. Everyone you see who has pulled their mask down then pushed it up again has touched the front of the mask. Misuse of masks may not negate the trapping of droplets, but it significantly increases the chances of transmission to surfaces by touch.

I'm not questioning the man's motives, Maggie, simply pointing out that even he admits that his findings are not based on science. There hasn't been enough time to establish the effectiveness or otherwise of masks purely by science as opposed to by anecdote or by informed speculation. However, wearing a mask as a precaution, even if you doubt their efficacy, is arguably more responsible than being an anti-mask rebel. I'm not reluctant to wear my mask, Jeri. But I'm wearing it when I have to, that's all.
