I am skeptical of this claim.
Can you provide a link?
I am
changing my mind on this one. I did a little poking around and found the study that the OP quoted from. I also looked at other scientific research.
It seems that yes, there is valid scientific evidence wearing a face mask in public does reduce your risk of getting a respiratory virus.
The CDC is making a rather weird argument. They are kind of saying that wearing a mask doesn't protect you (a claim that is not backed by scientific research) and yet they are saying that masks are required by health care professionals.
It is probably valid for the CDC to claim that masks may provide some protection... but
not enough to justify the cost particularly considering the shortage. This is a difficult message for the public to digest... the simple statement "masks won't help you" makes a better campaign.
The American public has difficulty with nuanced messages. In a case like this were effecting people's behavior in a specific way is important to overall health, I don't know what the correct answer is.
Here is the link to the study quoted in the OP.
