Prevention is achieved with improved sanitation, especially good water and sewer systems and proper washing of fruits, vegetables, and hands. Routine chlorination of water does not destroy cysts. A Brazilian root, ipecacuanha, and its active ingredient, emetine, have been given orally to treat dysentery since the seventeenth century. It was first given by injection in 1912 and, despite its toxicity, is sometimes still employed for both intestinal and extraintestinal amebiasis. Safer drugs, such as metronidazole, are usually employed but must be given over 10- to 20-day periods and relapses are frequent. Infection does not produce immunologic protection against reinfection with the same or another strain.
