Amebiasis. An increasing problem among homosexuals in New York City

During a five-year period at The New York Hospital, Entamoeba histolytica was identified in the stools of 20 men who had not traveled outside the New York area. All of the patients were found subsequently to homosexual. During this same period amebiasis was diagnosed in 30 men who had traveled; only two were homosexual. Of ten patients with E histolytica infection seen during the first year of this study, none were homosexual whereas eight of 11 patients in the fifth year were homosexual, suggesting a gradual increase during this period of this disease in the homosexual community.
