Amebic dysentery is a notifiable disease in Taiwan. The primary mode of transmission is contamination of either food or water by the cysts in feces1. 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. Arnebic dysentry is a communicable disease it is important to prevent and to control. Survey of potential sources of infection in the environment is absolutely essential to make such efforts effective.
