Further comments on oral transmission of Chagas' disease in Brazil: epidemiology, geographical distribution and viability of the infective parasite.
In 2006, Brazilian government received the international certificate of interruption of the vectorial transmission of Chagas' disease. However, outbreaks reported in Brazilian Amazon rainforest bear a regular occurrence and represents a relevant regional epidemiological gauge. The wild life cycle of the Chagas' disease transmission (i.e., triatomine-marsupial cycle) is present outside the previously reported endemic belt, ubiquitously, as infective triatomines can be demonstrated in Palm trees widespread all over the Amazon rainforest. As humans invade the rainforest, one is incidentally caught up and further becomes' an active part of American trypanosomiasis wild life cycle.
