The disease occurs more often in crowded and unsanitary places such as jails and mental institutions, but also occurs among homosexuals.(2) The world-wide prevalence rate of amebic dysentery is about 10 %(1), and there have been outbreaks in Taiwan in recent years in schools and mental institutions(3.4). Symptoms of the disease include diarrhea, occasionally abscess of the liver and brain (2.5); death can even result from the disease because of dehydration from diarrhea.
