Hey, this is what "officials" do best.  No one with half a brain believes one word they utter, and it's no damned wonder.

The CDC is just exactly the type of "organization" which should be shuttered overnight, never again to raise their head.  America doesn't need them.  WHY WOULD WE NEED THEM????  I mean, really, why would we?  They flip-flop just about as often as dumb butt Fauxchee.  That certainly is not helpful to our population and we can surely do without their contradictions.
