Introduction: Parasitic diseases and infections remain a significant cause of morbidity and mortality in the developing countries all over the world. Gaining data about parasitic infection is necessary to contrive suitable control programs and strategies to prevention and that is main aim of this study. This study evaluated frequency of intestinal parasites in Milad hospital, Tehran, Iran. Methods: During 2015-2016 about 13385 stools and 343 scotch tape samples were collected in Tehran. All specimens examined by direct smear and formalin- ethyl acetate concentration methods. All stool samples were well analyzed to diagnose any proglottids or mature helminthes that can be seen in stool in some conditions. Scotch tape method is an appropriate way to detect parasitic nematode of Enterobious vermicularis. Results: Data showed that 2.7% of cases had at least one parasite in examination. Frequency of parasites reported as B.hominis (1.3%), G.lamblia (0.8%), E.nana (0.3%), E.coli (0.3%), Taenia and C.mesnili (0.1%, 0.1%). Six cases of 343 scotch tape samples were positive for pinworm. Conclusion: Due to high standards of public health in Tehran, frequency of intestinal parasites is lower than other studies conducted in other regions. Demographic, socioeconomic characteristics and education can affect transmission of parasites and may involve in lifecycle completion.
