Yes, of course there are tons of autoimmune diseases (from mild allergies, to lupus, multiple sclerosis, and sympathetic ophthalmia), but Guillain-Barré syndrome is an autoimmune disease that's known to occur after otherwise banal infections or even vaccine shots. That's why I considered it more relevant to the OP than other autoimmune diseases.
