The American trypanosomiasis is also known as Chagas disease. It is the human tropical parasitic disease that occurs mainly in South America. The flagellate protozoan named Trypanosoma cruzi is the cause of the transmission to humans from other mammals mostly by the blood-sucking assassin bugs.
These assassin bugs are known by other names such as the kissing bug, chipo, chupanca, benchuca, barbeiro and vinchuca. There are other ways to get the disease including by ingestion of contaminated food, blood transfusion and fetal-maternal transmission.
