There are many causes of disease and I don't see the benefit of seperating the generic Cure Disease spell into Cure Disease (Vitamin Deficiency), Cure Disease (Parasitic Infestation), Cure Disease (Genetic Abnormality), Cure Disease (Senescence), Cure Disease (Radiation), Cure Disease (Prions) and so on in most campaigns. But if the setting would benefit from this level of detail, sure go ahead.
