Globally, there are an estimated 1.4 million casesof hepatitis A every year.

Hepatitis A is associated with a lack of safe water and poorsanitation [2].Dysentery is bloody diarrhea, i.e. any diarrheal episode in which the loose or watery stools contain visiblered blood. Dysentery is most often caused byShigella species (bacillary dysentery) or Entamoeba histolytica(amoebic dysentery) [3].Kharaa and Orkhon River are tributaries of the Selenge River-basin, in which many mining and other industries,agriculture, and residential areas reside.
