Factors Influencing Duration

Length of disability may be influenced by the severity of the disease at diagnosis, the degree of dehydration at the initiation of treatment, whether or not causative organisms can be easily identified and symptoms treated, the effectiveness of antibiotic treatment, the presence of complications, immunosuppression, and the age of the individual (disability will last longer in the very young and the very old).

Medical Codes

004 - Shigellosis; Includes Bacillary Dysentery
006.0 - Amebic Dysentery, Acute, without Mention of Abscess; Acute Amebiasis
007 - Protozoal Intestinal Diseases, Other; Includes Protozoal Colitis, Protozoal Diarrhea, Protozoal Dysentery
007.9 - Protozoal Intestinal Disease, Unspecified; Flagellate Diarrhea; Protozoal Dysentery NOS
009 - Ill-defined Intestinal Infections


With proper treatment, most cases of bacterial and amebic dysentery will subside within 10 days, and most individuals will recover fully within 2 to 4 weeks after beginning treatment. The prognosis for untreated disease varies with the immune status of the individual and the severity of disease. Extreme dehydration will prolong recovery and put the individual at greater risk for serious complications.
