Autoimmune disorders are characterized as systemic diseases because they affect the entire body rather than being localized. In these conditions, the immune system mistakenly attacks the body's own tissues, leading to widespread inflammation and damage across multiple organs or systems. This systemic nature means that symptoms can manifest in different areas of the body, making it a complex group of diseases that require comprehensive management.

In contrast, local infections primarily affect a specific area of the body, often causing symptoms such as redness, swelling, and pain in the affected region. Musculoskeletal conditions may impact multiple joints or muscles, but they typically do not produce systemic reactions that affect other body systems. Skin conditions are generally localized to the skin, with their effects confined to the dermal layer, although some can have systemic implications if severe, they are not classified as systemic diseases per se.
