It's not rocket science. South Korea and Taiwan have used masks as a key part of their successful anti-CV strategy for 2 months.
And it's not "sick looking" people coughing, it can be a healthy-looking asymptomatic spreader at conversational range. Think about the young cashier at the grocery store, sharing breaths with the last half-dozen customers, while passing cash back and forth.
This screen cap from the below linked video does not do it justice. Watch the video to see how much airborne crap is exchanged at conversational range.
This video goes with the screen cap at 13. The still image does not do it justice.
Watch this video starting at 14:40 to see how 2 people simply talking face to face exchange germs and virus. The screen capture above does not do it justice.
This is why its important to wear masks in public around people during the pandemic.

The benefits of wearing masks is just staggeringly obvious.
Our Surgeon General lost ALL credibility immediately when he came out with the totally ridiculous “masks don’t work”.
The video Travis posted clearly shows how many viral particles are put out even by talking. And sneezing or coughing without covering is 1000X worse.
Since the virus particles can live in the air up to 3 hours, the only way to reduce the spread is for EVERYONE to wear masks while outside of the house.
The Czech Republic is doing this - and like every other country that is mandating masks, their CV19 infection curve is infinitely flatter than the countries who have not mandated masks. Chris Martenson (Peak Prosperity guy) has an excellent chart in one of his recent videos comparing the growth curve of the “no masks” countries (explosive growth) to the “masks required” countries (much slower growth).
It’s really a total no-brainer..they only told us “masks don’t work” because they didn’t have enough.
