from Section 7 - Protozoal Infections
Published online by Cambridge University Press: 18 June 2025
Amoebiasis is caused by the protozoan parasite Entamoeba histolytica and has a worldwide distribution. It is estimated that 40–50 million cases of amoebic colitis and liver abscess occur annually with 100,000 deaths (Shirley et al. 2018). The infection occurs all over Africa. Transmission is through the faecal–oral route and therefore the infection can flourish whenever sanitation and hygiene is poor. Outbreaks of amoebiasis are frequent during disasters or crises when people are crowded together in refugee camps, after floods and during famine or war.
