14â16 The neuronal loss in Chagas heart disease has been postulatedto occur predominantly during the acute phase of the infec-tion, with participation of 3 mechanisms: direct parasitism ofneurons, degeneration caused by periganglionic inflamma-tion, and antineuronal autoimmune reaction.nly inthe late 1940s, through improved specific serological tests todetect antibodies against T cruzi, the clinical syndromes ofmegaesophagus, megacolon, and heart failure, by then ofunknown cause, were ascribed to Chagas disease, and the firstreport of cardiac neuronal damage appeared in the literature.
The incubation period of vector-borne acute Chagas disease is thought to be 7-14 days, but definitive data are not available because persons who live in areas of active transmission are generally continually at risk for exposure to the vectors.cute phase. In most instances of acute T cruzi infection, a specific diagnosis is not made because of the nonspecific nature of the signs and symptoms and because most cases occur in poor people who have limited access to medical care. Acute Chagas disease carries a mortality rate of less than 5%.
