The prevalance of various intestinal parasites has been determined from a study of 40, 267 people from both urban and rural areas of Khorasan province, Iran. Except for G. lamblia, T. hominis, and H. nana, the prevalence of intestinal parasites seems to be lower in this province than in other areas of Iran. The incidence of infestation in village females was higher than in village males, but was similar in the two sexes in the towns and cities. Of those infested, more than 20% from urban areas and 35% from rural areas had multiple infestations.
