> I’ll definitely want my country’s Secretary of Health to be a doctor who understands public health
If by “doctor” you mean, as people usually do in general conversation, an MD (or DO), why? Public health is an entirely different discipline from medicine, with its own series of professional degrees. As is public administration. As is public policy. Why would a top-level public administrator and public policy professional in the field of public health need to have a professional degree in medicine more than one in public health, public administration, or public policy?
OTOH, your Surgeon-General or equivalent should definitely be a medical doctor.
