They are _now_ the centre for disease control and prevention
What do you mean?
Still well within the realm of health and certainly affects communicable diseases (an unhealthy population is more prone to worse effects of disease).

What was the CDC's original mission?
Did it execute it competently?
Why is it now involved in areas other than communicable diseases?
Do people in organizations seek to increase their power and influence?
Do they do this by enlarging the scope of their organizations' missions?
How is this notionally science-based entity being influenced by other factors?

I actually suspect this role was thrust on the CDC because they are generally supported by everyone (everyone sane anyway). I'm not a fan of this having happened because they should be too important to get mixed into politically poisonous debates.
That said, it'd kind of inevitable that they run a course like that because constantly doing good non-controversial work banks political capital and the politicians are gonna try to harness organizations like that for their own ends.
How, exactly, are folks (who are not versed in medicine) supposed to get this information from a trusted source?
