Over the years the position of the honourable of minister of health has seemingly been the exclusive right of medical doctors, though I'm not sure this has any constitutional backin. Any attempt to alter this tradition will lead to serious agitations by NMA often times resulting in strikes.

Despite this tradition, the health care system continue to be shambles. Going through the Wikipedia page of the current director general of the world health organisation, the first thing I noticed was that he is not a train medical doctor yet he's been doing exploits in the medical field and has held different leadership positions. Currently in Nigeria, I can not say for certain that a microbiologist (non medical microbiologist) has a place in our healthcare system.

Can making the position of the minister of health in Nigeria open to all stakeholders in the health industry be the needed adjustment for things to begin to take shape in our healthcare system?

Management is different diagnosing illness.
There is a course called Healthcare Administration I dont know if it's on offer in any Nigerian university.

Trust me, in a country like Nigeria where a minister of health that is a medical doctor is incompetent in discharging his duties as a minister... You can imagine how poorly a non-doctor would perform given such position.
It is a Nigerian problem I think... unfortunately, the best fits still don't get the jon done here

At this state of Nigeria, we need medical doctors to be the Minister.

Maybe if Nigeria develops, we can look for managers.

There is a difference between management and diagnosis. Although, most ministers of health are usually doctors but that doesn't mean they are capable of managing affairs as a health minister. Come to think of it is there any legal backing saying that doctors should be ministers of health?
