<unk>  is a worldwide infection whose incidence is highly dependent on sanitation practices. Worldwide, the annual incidence of<unk>  is approximately 50 million cases. Prevalence of<unk>  ranges from approximately 4% in the USA to 50% in certain regions in developing countries. It is thought that the prevalence of E. dispar is much higher than that of E. histolytica, but E. dispar is frequently undiagnosed because colonized individuals are almost always asymptomatic. Worldwide, approximately 500 million individuals are thought to be colonized by E. dispar. Worldwide,<unk>  is associated with 100,000 deaths each year and a case-fatality rate of approximately 200 per 100,000 cases. Elderly patients and young children are at higher risk of developing<unk>  than adults, but adults are at higher risk of developing amebic liver abscess than children. Men are at higher risk of developing invasive<unk>  and amebic liver abscess than women. In the USA, the prevalence of<unk>  is much more common among Hispanic and Asian immigrants and immigrants from Pacific Islands. However, the higher prevalence is though to be due to the immigration status, not due to ethnic differences.
