There are credentials and there are credentials, right?
The difference between a trained lawyer or accountant and someone with a lot of exposure to such knowledge is very specific skills and procedures. The difference between someone who is a trained manager with a degree and someone who's managed a medium sized organization is more or less nothing just an ability to use jargon.
I've actually looked online courses and documentation on epidemiology and public health. Unlike medicine (which I know nothing of) or advance mathematics (which I know and I know it take specialized skills), epidemiology seems to be a "smattering" sort of fields. A mix of public policy, simple medicine, biology and experimental methods and statistics. I could be wrong but it seems a field that's wide, not deep.
