ISRO, you have admirable patience. Masks= Good, No mask= Bad. Easy, even the cretins here could do it.
Exactly how long has the medical community agreed with your assessment?
How effective are cloth masks at containing moisture vapor?
Medical communities in most countries now are recommending masks, but that probably doesn't ring a bell either I would assume.
Containing? You missed the mark again Backroads. It is about limiting travel distance of said cough or sneeze.
Except for the last couple of months, the entirety of medical history is against masks for healthy and asymptomatic people.
How much less than zero can the distance of a sneeze or cough be limited? Of course you realize that asymptomatic infected people are not sneezing or coughing.
The virus living in the moisture laden air we exhale would then be the only means of transmission, no?
As previously stated, cotton masks do nothing to contain that, and a visual aid of this will be made apparent in the upcoming winter months.
No one will be spared exposure, learn to swim.
