"Prevalence of Intestinal Parasites among Children in Day-care Centers in Damghan - Iran"

In order to identify the prevalence of parasitic intestinal infections and to determine the impact of some factors, such as age, health houses, education, environmental health etc, on infection, this survey was carried out on 461 stool specimens and scotch tapes obtained from children resident in day-care centers in Damghan city, Semnan province, Iran. The samples were tested using formalin-ether concentration and Graham methods. The analysis of the results showed that at least 68.1 percent of the individuals tested, were infected with one species of pathogen or non-pathogen parasites. The rate of infection for Enterobius vermicularis, Giardia lamblia, Entamoeba histolytica, Ascaris lumbricoides, Hymenolepis nana, Entamoeba coli, Blastocystis hominis, Iodamoeba butschlii and Chilomastix mesnili was 33.8%, 26.2%, 2.4%, 3%, 4.8%, 5.8%, 4.8%, 2.7% and 4% respectively. A significant difference was seen between the rate of infection and parents’ education (P<0.005) but was negative regarding age, sex, and health houses. It is concluded that sanitary measurements should be conducted in such centers to decrease the rate of parasitic infection.
