Prevention of Amebiasis
To prevent amebiasis, contamination of food and water with human feces must be avoided—a problem complicated by the high incidence of asymptomatic carriers. Uncooked foods, including salads and vegetables, and potentially contaminated water and ice should be avoided in areas with poor sanitation. Boiling water killsE. histolyticacysts. The effectiveness of chemical disinfection with iodine- or chlorine-containing compounds depends on the temperature of the water and amount of organic debris in it. Portable filters provide various degrees of protection. Work continues on the development of a vaccine, but none is available yet.
