Correction: Auto-immune diseases, and there are many, are when the body has a hyper-immune response to self. The immune system attacks a particular part or a system of a person's own body - self attack. AIDS is an acquired immune deficiency, meaning that that body for some reason develops an inability to mount a defense against either outside intrusions, as in the case of pathogens, or is unable to defend against inside attacks like cancer. Auto-immune and AIDS may involve dysfunction of the immune system, but that is where the similarity ends. In reality, they are two opposite ends of a functional spectrum.
