55%. This is why I say using a bandana has to be just about as good.
All these fools in the grocery store wearing masks and no eye protection. They're wearing 2/3rds protection thinking they're covered.
The point is really for health care professionals that interact with sick people, and sick people to wear masks. A mask on a healthy person is next to pointless.
