A06: Amoebiasis

Amoebiasis is a group of illnesses caused by a tiny parasite called Entamoeba histolytica, which often infects the bowels. The parasite can be picked up from contaminated food or water, or from surfaces that have been infected with fecal matter carrying the amoeba. Many people with amoebiasis don’t experience symptoms, but some may have loose stools, stomach pain, and weight loss. In more severe cases, the amoeba can invade other parts of the body, such as the liver, and cause abscesses or severe illness. This is called invasive amoebiasis. Generally, the disease gets worse over time if it's not treated. The parasite can live in the intestines for months to years without causing symptoms, but it can still be spread to others during this time.
