👉 Self-infection, or self-infection, refers to a rare condition where a healthy individual's immune system mistakenly attacks and destroys their own cells, effectively treating the body as an internal source of infection. This phenomenon can occur in various contexts, including autoimmune diseases, where the immune system produces antibodies that target self-antigens, and in certain genetic disorders like X-linked agammaglobulinemia or chronic granulomatous disease. In these cases, the immune response is directed against the body's own tissues, leading to inflammation and tissue damage. While self-infection can sometimes be a benign occurrence, it often indicates an underlying immune disorder that requires medical intervention to manage symptoms and prevent further complications.
