The latest push for masks has been as "source protection"
"It's not about you, it's about being considerate & not spreading the infection to others," the panic-mongers said.
Science says masks do not even work as source protection.
They make source infection worse - even when N95s are used by trained surgeons.
If you're a DEMOCRAT, I'll break it down for you.
In a large, well designed clinical outcomes study w/ a valid control group & consistent standards, doctors wearing face masks had 4.7% post operative wound infection rates for patients.
Those with no masks had 3.5%.
Wearing a mask made infection 34% more likely.
If surgical and n-95 masks do not reduce (and seem to actually increase) infection rates when used by trained professionals, what hope do they have in the general population?
And viruses are MUCH harder to stop than bacteria.
Now, imagine a cloth mask on a 5 year old in a classroom.
