Recent CDC buffoonary: when they said mask are no longer needed outdoors when not in crowds, they cited a stat that "less than 10% of transmission occurs outdoors."
Ok, so that's technically correct, but it's like saying "less than 10,000 people a year get bitten by sharks" when the actual number is 100. So yeah, that's true, the correct number is less than 10,000.
As for Covid transmission, the best scientific estimate is about 0.1% occurs outdoors. Well sure, that's less than 10%, but please quote actual statistics! People are confused enough already.
