[General survey of the present distribution of helminths in Iran and comparison with those of past years].
In this paper the literature on helminthiasis in Iran is reviewed and the distribution, prevalence and intensity of infections caused by helminths are discussed. A comparison of prevalence and intensity of infections was accomplished in the recent 10 years by the author. Hookworm infections are found mostly in the north along the Caspian sea, but its prevalence is declining. Trichostrongylus are found in Iran with a high prevalence in central country. Schistosoma haematobium is found in one Province in the south, but its prevalence is declining because of large scale control activities. The Guinea worm rarely occurs in Iran. The prevalence of Fasciola hepatica is high among livestock and is occasionally found in man. Taenia saginata is found in most parts of Iran. Taenia solium is seldom found in animals with a prevalence of 0.03%. Trichinella spiralis is infrequently found in animals. Dioctophyma renale is found in straying dogs in the north or Iran, the percentage is 13-35%. Oxyuriasis is widespread among children.
