I hope that's just a simple turn of the phrase you have used there, but its a dangerous thought. We have known that using masks during a pandemic saves lives by decreasing the transmission of airborne viruses - and that fact has been reasonably well documented for at least 100 years.
Yes wear the masks I guess. It makes people feel better.
CDC calls on Americans to wear masks to prevent COVID-19 spread
JAMA editorial reviews latest science, while case study shows masks prevented COVID spread
When I add a chart of the Covid-19 incidence reports for Missouri compared to a few other states we can see that it's only recently that California, which is on a exponential growth curve right now, has passed that previously higher infection rate.
The last thing anyone there wants is to catch this virus which is now loose over here that has filled most of our ICU beds to capacity.
