The aim of the study was to determine the prevalence and evolution of intestinalis parasites in hospital area. For the present investigation, 2401 samples, including 403 urines and 1998 stool, were collected. The age of patients ranged from 2 months to 87 years with a mean of 24.24 ± 18.58 years. Females predominated (51.1%) with a sex ratio of 1.04. The average prevalence of parasitic infection was 15.58 %. Throughout the years, it was found that the infectivity rates varied significantly, Chi2 = 87.522 p = 0.0000. There was no significant variation between sex and parasitic infection, p> 0.05. Fourteen species of parasites were identified, including 11 in the feces and urine 3. In stool (n=1998), the prevalence of parasites were as followings: Entamoeba histolytica 4.80% (96/1998) , followed by Ascaris lumbricoides 4.20% (84/1998) , Trichomonas intestinalis 3.35 % (67/1998), Giardia lamblia 1.65% (33/ 1998), Hymenolepis nana 0.70% (14/ 1998) Schistosoma mansoni 0.60% (12/ 1998), 0.55% Taenia saginata ( 11/1998 %2
