Although 90 percent of E. histolyticainfections are asymptomatic, nearly 50 millionpeople become symptomatic, with up to 100,000 deaths yearly.Those infected by Entamoebaare mostly colonized by either E. histolytica or E. dispar. E.histolytica is the pathogenic form and can cause amoebic colitis and extraintestinal amoebiasis.Infection occurs worldwide, with a higher prevalence in countries of low socioeconomicstatus and poor public health.A three-year study conducted in Bangladesh showed that 2.2% of dysentery cases were caused by E.histolytica in preschool children.[7] In rural areas of Mexico, the seroprevalence of E. histolytica has beenreported as high as 42%.In developed countries such as the United States, amebiasis infections are rare, accountingfor at least 5 deaths per year, and are commonly seen in individuals that have had exposureto endemic areas such as immigrants or recent travelers.
Amebiasis is a disease caused by a one-celled parasite called Entamoebahistolytica.Puts anything into their mouth that has touched the feces (poop) of a person who is infected withE. histolytica.Swallows something, such as water or food, that is contaminated with E. histolytica.Swallows E. histolytica cysts (eggs) picked up from contaminated surfaces or fingers.Only about 10% to 20% of people who are infected with E. histolytica become sick from theinfection. The symptoms are often quite mild and can include loose feces (poop), stomach pain,and stomach cramping. Amebic dysentery is a severe form of amebiasis associated with stomachpain, bloody stools (poop), and fever. Rarely, E. histolytica invades the liver and forms an abscess(a collection of pus). In a small number of instances, it has been shown to spread to other parts ofthe body, such as the lungs or brain, but this is very uncommon.

Medicines called antibiotics are needed to treat amoebic colitis.Metronidazole is the usual antibiotic that is used but tinidazolemay be a good alternative. A second medicine, usuallydiloxanide furoate, is then used to get rid of any parasites thatmay still be living in your gut. After treatment is completed,testing of a follow-up stool sample is advised to ensure that theparasites have been cleared.
Thoroughly wash fruits and vegetables before eating.Avoid eating fruits or vegetables unless you wash and peel themyourself.Use bottled water and soft drinks from sealed containers.If you must drink tap water, boil it for at least 1 minute, or use a store-bought “absolute 1 micron” filter and add disinfecting chlorine, chlorinedioxide, or iodine tablets to the filtered water.
