How the CDC’s restrictive testing guidelines hid the coronavirus epidemic
The mask guidance is confusing as well.  I get they are trying to preserve masks for medical staff.  But, they also say it's mainly spread by coughing, sneezing, and resulting spray of bodily fluids.  Surely even a scarf around your face would have some benefit? Yes, I get that the virus is small enough to pass through, but some deflection is better than none.
