This is a very dangerous statement because it claims absolute knowledge of transmission.
Basically, he's saying, "If you do it my way, there's no chance of error" when he should be saying, "We need to find out if there things about our protocols that don't work."

We are now clealy trying to treat disease with a political poultice.
See #28. It is agrees 100% with your excellent post.
