The parasites multiply and eventually cause chronic symptoms related to the particular involved organ or organs that can include life-threatening cardiac failure, arrhythmias, poor gastrointestinal motility, meningoencephalitis, or death.
Humans who live in poor or primitive housing conditions that border or invade the habitats of Triatominae bugs cause a break in the normal life cycle of the insect vectors bugs and their usual hosts over types of animalstermed the sylvatic cycle. The disease cannot be cured in this phase, however.

Infants born with the infection should also be treated. The life cycle of T. Even when colonies of insects are eradicated from a house and surrounding domestic animal shelters, they can re-emerge from plants or animals that are part of the ancient, sylvatic referring to wild animals infection cycle.
Replication resumes only when the parasites enter another cell or are ingested by another vector. Fortunately, these forms of transmission occur very infrequently. However, in regions where the sylvatic habitat and its fauna are thinned by economic exploitation and human habitation, such as in newly deforested areas, piassava palm culture areas, and some parts of the Amazon region, a human transmission cycle may develop as the insects search for new food sources.
This is especially likely in zones with mixed open savannah, with clumps of trees interspersed by human habitation. Vaccination with Trypanosoma rangeli has produced positive results in animal models.
