The virus is contained in your mouth and is primarily spread via leaving one person’s mouth and getting somehow into another’s, usually by getting on their hands in between.

Speaking for two minutes releases as much saliva as a sneeze.

Masks are only a little bit useful in stopping me from getting the disease, but they are VERY useful in stopping you from giving the disease to others. Asymptomatic spread is the secret weapon of this virus. The people spreading it don’t know they have it.

"but they are VERY useful in stopping you from giving the disease to others."

No, they are not.
