List of diseases

This is a list of common, well-known or infamous diseases. This is neither complete nor authoritative. This is not intended to be a list of rare diseases, nor is it a list of mental disorders.

This list includes both common names and technical names for diseases. This is deliberate; where multiple names are in common use for the same disease, all of those names should link to the main article for the disease
