title: Socio-agricultural factors and parasitic infections in the Caspian littoral region of Iran.
abstract: Surveys for intestinal parasites in villages in the Babol area of the Caspian littoral region of Iran have been conducted for five years. During this period, mass chemotherapy and individual treatment have been administered. While the overall prevalence of parasitic disease was reduced after these campaigns, reinfection took place repeatedly, and at a rapid rate. This paper re-examines the prevalence of seven helminth species (Ascaris lumbricoides), hookworms (Ancylostoma duodenale and Necator americanus), Hymenolepis nana, Strongyloides stercoralis, Taenia saginata, Trichostrongylus spp. and Trichuris trichiura) on the basis of geographical and socio-agricultural criteria. The considerable differences in the prevalence of these parasitoses--even between neighboring villages--emphasize the variability of human ecology in the region under study.
