(Digenea: Gymnophallidae), a new human intestinal trematode reported from a Korean woman who complained of epigastric discomfort, has been shown to be highly prevalent among the villagers of a southwestern island of the Republic of Korea. For the detection of human infections, fecal examinations were conducted on the inhabitants of a seashore village, where the first patient with a infection had resided. Of 98 inhabitants examined, 70 (71.4%) were infected with various intestinal parasites; among them, showed the highest rate of egg positivity 48 of 98 (49.0%). Individual worm burdens of , as measured by collection of adult flukes after anthelmintic treatment and purgation, ranged from 106 to 26,373 specimens (average per infected case = 3,326). There was no sex-related difference in the prevalence of , and the age distribution of the infected cases showed a relatively even pattern. This study confirms that human infection by is not an incidental one and provides the first evidence of its high prevalence on this Korean island.
