The disease is spread by water and food that have been contaminated by feces of persons previously infected. The symptoms are caused by toxic substances produced by the infecting organism.

Treatment includes antibiotics to destroy the infecting bacteria and restoration of fluids and electrolytes by injection. Magnification unknown.
