Dysentery (flux or bloody flux) broadly refers to gastrointestinal disorders
characterized by inflammation of the intestines, especially the colon.
Dysentery is most often caused by Shigella species (Shiga
bacillus, is the most virulent of the four serogroups of shigella)
or Entamoeba histolytica (amoebic dysentery). The first one is
associated with environmental conditions where poor sanitation is prevalent,
is most commonly found in tropical areas.
The signs and symptoms of dysentery usually last five to seven days but the
course of the illness varies among individuals, as do symptoms.
Exposed individuals may experience either mild, severe, or even no symptoms at
Dysentery is commonly spread among humans through contaminated food and water.
Animals can also be infected and spread the disease to humans.
Untreated dysentery can lead to severe dehydration and may be life-threatening.
