The aim of this study was determination of relative frequency of
   intestinal parasites in Hamadan military  base in 1998.

          406 persons of residents were selected randomly and their  stool
   samples were collected and related check lists were completed by referring
   to the doors. The samples were examined by formol-ether method.

          The detected results showed parasitic infection in 43.8% of  residents
   with the maximum percentage associated with Ascaris (42.7%) and Giardia
   (21.9%) . Age group of 31-40 , primary school students and housewives had
   more infection rates . Also small families (<3) showed the lowest rate of
   infection.

          According to this fact  that  the source of providing  vegetables for the
   military  base and Hamadan city is the  same  , it seems that the sanitary
   standards are at higher levels in the base .
