THE DISABLING TROPICAL DISEASES: AMOEBIASIS
Amoebiasis, caused by a parasite that invades the intestines, was formerly regarded as a tropical disease. However, we now know that numerous cases of even the severe form, amoebic dysentery, are found in temperate climates, and it is widespread in its mild form.
Infection from this organism can be prevented by taking proper sanitary precautions with respect to food and water in areas where public sanitation is poor. The disease can also be passed on by someone who handles food, and who may not know that he is harbouring the invisible cysts of this parasite. This can happen because individuals with the mild variety may experience only minor symptoms such as headache, occasional nausea, flatulence, fatigue, and bowel irregularity.
It is most important not to neglect any symptoms of amoebiasis. You are very apt to give the disease to someone, perhaps a child, who may develop it in its severe form. In addition, mild cases may develop into amoebic dysentery, with abdominal pain and diarrhoea, often accompanied by blood-streaked stools and, in severe cases, chills and fever. Severe amoebic dysentery can cause death. There is also the risk that the parasite may travel to the liver and produce an abscess there. If not treated properly, such an abscess can prove fatal.
Amoebiasis can usually be treated with success. Medicines have been developed for all types of this disease. Even people who have had chronic, resistant cases should not be discouraged, but should again consult their doctors, as they can probably benefit from new treatments.
