I get that, but mask usage is not 100% for many reasons. Larger droplets hitting the wearers mask from the outside are also possible for many reasons.

- scoutt 6y agoMask usage is good enough. Even better if every person in the world uses them. Want 100% effectiveness? Then stay at home.
- jsight 6y agoSorry, I didn't mean that it isn't 100% effective, although that is true too. I meant that not everyone will wear them. The improvement is still >0 in protecting oneself.
