What a bunch of horse manure! You get sent to 3 other sites and just end up at a CDC recommendation.
They did NO studies.
Studies would have to have followed 2 large groups of people-one group wearing masks, the other group wearing no masks and the study would have to have been done for a period of months.
This was not done.
The CDC never counted cases of H1N1 in 2009. They made 2 wild assed guesses, high and low and settled on the number in between.
They stopped counting in 2009 and switched to guessing in 2009 and 2010.
And you KNOW they didn’t count asymptomatic suspected cases as “H1N1”.
This is all partisan BULLSTALIN.
