I emphatically do NOT trust the CDC, because they have lied to us before. That is not rumor, it is fact. They even admitted to having "exaggerated" the risk of transmission of HIV through hetero sex, back in the 1980's, but said they felt their lies were justified in order to get more government money for research.

And the CDC is an intensely political organisation, as one can clearly see from their lobbying for gun control.
