Sex:
No difference exists between males and females
in the prevalence of acute phase, whereas chronic
chagasic cardiomyopathy occurs earlier and is
more severe in males than in females, chagasic
esophagopathy is more frequent and severe in males
than in females.
Age:
Symptomatic acute phases mainly occur in newborns
(congenital infection) or young children. Chagasic
esophagopathy is observed more frequently in the
second decade of life, and chronic chagasic cardiomypathy
and colophaty are generally detected later, in
the third, fourth, or fifth decade of life.
Race:
Morbility and mortality are higher in black persons
of mixed race or white children younger than 2
years who are acutely infected. Chronic chagasic
cardiomyopathy also seems more severe in black
persons than white persons.
