What’s the risk of transmission between a non-masked, infected person and someone wearing a mask that isn’t infected and maintains a distance of six feet?
How much asymptomatic spread is actually occurring? How many people have recovered and/or developed immunity and are no longer able to spread the virus?
This is a brand new virus, I don’t think we 100% know the answers to all these things. However there’s a reasonable assumption from what we’ve seen so far that masks do help mitigate transmission of droplets. There’s always a debate about asymptomatic vs presymptomatic spread. Regardless it seems pretty clear that people can be feeling fine and then spend time with others and Covid spreads.
Lastly, I said it previously if research shows that masks do absolutely nothing in the future I’m 100% ok with saying I/we were wrong. But for now wearing a mask is not a huge deal and I’d prefer to be cautious if it’s possible to help others around me. If we find out we were wrong, then oh well, lesson learned and we’ll never have to wear masks in the hospital again.
Why people are putting so much energy and anger in to this is beyond me.
