Good question.
On the most grandest level, all chronic diseases known to man are derived from psora, which resulted from scabies, the skin itch.
Per Hahnemann's miasm theory,
"'Psora is that most ancient, most universal, most destructive, and yet most misapprehended chronic miasmatic disease which for many thousands of years has disfigured and tortured mankind... and become the mother of all the thousands of incredibly various chronic diseases...' [Chronic Diseases, p9]
From psora evolved two sexually caused miasms, Sycotic from gonorrhea and Syphlitic from syphilis, and various chronic diseases evolved from these miasms.
More recently, Tuberculosis was recognized as creating a miasm, known as pseudo-psora, new psora, thought to mutate or evolve from psora, which Hahnemann likened to a multi headed hydra, meaning untreated psora is able to morph to new forms.
Diabetes is thought to be in the tubercular miasm.
Hahnemann wrote of latent psora, the various aches, pains, ills and conditions caused by psora, some show after acute conditions and also as one ages and psora progresses in the body. Recently I know someone who, now middle aged, got vertigo attacks after pneumonia. That suggests latent psora and also various antipsoric remedies that have vertigo as a rubric along with a mother who had vertigo suggesting passing on of an inherited miasm.
For example, middle age brings attention to incontinence, loss of bladder control, which is highly advertised on TV and ads for products like Depends, Tena and drugs to control it as so many people develop that condition.
Is it possible this is group latent psora as one moves through middle age???
Cancer is also thought of as a misam with Carcinosin as it's nosode and it's own list of symptoms to identify it especially having cancer in families and being extra fastidious.
Today, most people are treated allopathically if they get a sexual disease, TB, and most psoric based conditions and disease, thus, suppression allopathically from these miasmatic illnesses especially from psora means there will me new miasms in the future as most of the world's inherited psora is being suppressed but not homeopathically eliminated for newer generations.
Just like bacteria mutates after overusage of antibiotics so does psora. AIDS has been discussed as possibly being a new miasm.
Kent, another highly regarded homeopath made a connection with sin and the miasms, thus taught and practiced based on that Adam ate the apple viewpoint:
"Kent, in his Lectures, then greatly enlarged upon the theory, proposing that Psora was the foundation of all other illness, without which mankind would be pure and healthy both in mind and body, as in the Garden of Eden. He thus regarded Psora as being equated with the 'Fall of Man' and with original sinfulness. He portrayed Psora in this highly moralistic light as also being the foundation of the sexual miasms that came later.
"I think it is abundantly clear from these quotes that Kent took a very puritanical and moral line about the origins of disease within the human race and he apparently felt that Psora was equivalent to Original Sin or the Fall of Man.
Hahnemann also pointed out the origins of his theory and the remedies that he decided had the power to eradicate the symptoms of a particular miasm."

Okay, it's only a partial fit...
