Diseased are humans who are infected with a bacterial or viral infection that causes fatal mutations in humans. This infection acts by causing decay of the epidermis and dermis, leaving huge abrasions and exposing the muscles. They have lower IQ than an uninfected human, but the Diseased are still able to use firearms, as well as not attack each other. They appear in BloodRayne.
