A 'manufactured' disease?

Is fungal disease so very rampant in society? Apparently. How can we know this? Vast numbers of antifungal drugs are manufactured and sold. Then prescribed by doctors.

So, is the disease 'manufactured'?

Create an alleged disease and then provide a pill to 'beat' it. It has to work as the circumstances in which it is 'needed' can be engineered.

But, maybe not.
