      Amoebic infection is often chronic infection caused by intestinal parasites called Entamoeba Histolitica. Diarrhea, abdominal cramps, sticky stools and sometimes blood and mucus in stool are its common symptoms. Once detected after stool examination, a course of antiamoebic treatment usually cures the disorder. It is spread by feco oral route. Poor hygiene and poor sanitation are two important factors which are responsible for transmission of the parasites. Also bacterial intestinal infection has the same cause aside from eating undercooked food. Prevent reinfection by taking few measures such as drink boiled water. Stay away from eating street foods. Follow proper sanitation and hygiene measures such as wash your hands after defecation. Eat cooked food. Avoid eating raw vegetables.
