[Prevalence of infection by intestinal parasites in north Lebanon: 1997-2001]

Abstract

We determined the prevalence of intestinal parasites in the north of Lebanon between 1997 and 2001. We analysed the parasitology records of 17126 patients and evidence of parasitic infections was found in 5 713 [‎33.35%]‎ cases. There was no significant difference in prevalence for males or females for any of the parasites. The most prevalent parasites were Entamoeba coli [‎38.45%]‎, Ascaris lumbricoides [‎37.14%]‎, Giardia lamblia [‎15.39%]‎, Ent. histolytica [‎4.57%]‎ and Taenia sp. [‎3.3%]‎. A comparison between our data and results of previous studies in Lebanon in 1937, 1939, 1956, 1967 and 1993 showed an increase in the prevalence of A. lumbricoides and G. lamblia in the period 1997-2001, with less marked changes in the prevalence of the other parasites
