There are no significant environmental or animal reservoirs of the parasite. Thus, it makes the goals of a vaccine strain and disease eradication more feasible [9].
The cause of amoebiasis is spread to one another only through man and without any involvement of any parasite vector
After infection, it may take from a few days up to two to four weeks before developing overt symptoms. However, some people may carry the parasite for several months or even years before they become ill. Thus, due to the slight variations in incubation period, tracing the cause of the illness requires that one knows what he/she ate and drank and the places traveled in the weeks/months before becoming ill [8, 10,12].
