   Algid cholera (Med.),
      (a) A term formerly used for a classic untreated cholera
          (also called Asiatic cholera, caused by Vibrio
          cholerae); it is marked by three stages that succeed
          each other. These stages include a watery diarrhea
          stage, a stage of shock and collapse characterized by
          a cold skin and, the final stage of high fever.
          Patients usually die at the second stage of the
          disease.
      (b) In its modern use, algid cholera refers to a cholera
          that has entered the second stage of the disease. In
          the 19th century, the term algid cholera referred to
          Asiatic cholera, to distinguish it from other less
          specific intestinal afflictions.
