This is an epidemiological study of the prevalence of intestinal parasites and their effect on hemoglobin level in pre-school children. The study was carried out during the period December 1998- February 1999 in Al-Jiftlik area- Jordan Valley. 220 pre-school children were included in the study, 116 males and 104 females. The findings were discussed in relation to children’s socio-economic, hygienic background and environmental conditions in the study area. 100 of the children were infected at least with one type of intestinal parasites. Prevalence rates of encountered parasites in the infected population were lower in younger children (<4years old), than in older children (5-6 years old). The results also showed that males were less affected than females.
