Chagas disease basically known as American trypanosomiasis,mostly prevelant in Latin America, is a tropical parasitic disease caused by the protozoan Trypanosoma cruzi. It is spread by the bitting of the kissing bugs.The disease may also be spread through blood transfusion, eating food contaminated with the parasites, organ transplantation, and by vertical transmission.
Diagnosis of early disease is done by finding the parasite in the blood using a microscope.Chronic disease is diagnosed by finding antibodies for T. cruzi in the blood.
Prevention can be done by eliminating and avoiding the kissing bug bites,screening the blood for transfusions,medication such as benznidazole or nifurtimox can be given at early stages,but no such vaccine has been discovered so far.
