You are still personally protected just the same. And if you are personally protected, you are less likely to catch the virus and spread it along.
- dusted 6y agoI'll bite :) let's say your mask protects you from N% of the droplets you inhale. and let's say MY mask protects you from N% of the droplets I exhale. Now, are you more protected if: a. Only I wear a mask. b. Only you wear a mask. c. We both wear a mask.
- NeutronStar 6y agoI'll bite. You are more protected with 2 masks. However, your not unprotected with only 1 mask. Therefore, having a valve mask wouldn't protect others from you, but you would still be protected from others. Now if both don't wear mask, we have an issue.
- jjeaff 6y agoBoth wearing masks, obviously. But that isn't what the title says. It is saying that a mask with a valve doesn't slow the spread of covid. Obviously, one of us wearing a mask is better than neither of us wearing a mask. I think maybe the implication is that if the person wearing the mask already has covid, it isn't going to slow the spread to others. Which makes sense. But if you at least wear a valved mask, you will be less likely to catch covid in the first place.
