An appraisal of the epidemiology of Trypanosoma cruzi serology in Brazil

Abstract

A large bibliographic survey provided data on Trypanosoma cruzi serology covering the period 1948-1984. Epidemiological-demographic methods provided an estimate of 11% for the prevalence of positive serology in Brazil, by 1984. Significant temporal trends were observed for most of the Brazilian geographical regions as well as for Brazil, as a whole. The parabolic curve that fit best for the entire country, indicates that by 1991, the incidence of new positive serology would be close to zero. This conclusion needs further fine-adjustment, since the forecast point is somewhat distant from the measured period.

“…The clinical manifestations of cardiac damage are variable. In the most benign cases, alterations occur in cardiac rhythm with small changes in diastolic function, up to serious atrioventricular block, complex ventricular arrhythmias, and diffuse damage to ventricular contraction by chronic myocardial aggression, characterized as chagasic cardiomyopathy (7).…”
