I live in a retirement community. Many of my neighbors do not believe masks help stop the transmission of COVID-19. They use the Nextdoor app to post their feelings and “facts”. I usually try to convince them otherwise, but it seems to be fruitless. Today someone posted a picture of a warning on the box of disposable surgical masks (attached) to prove their point that masks, other than N95, don’t work. Can you give me some information that will help explain this warning and why these type of masks help. Thanks.
