Here an answer. Everybody is invited to debate. The person who wrote it is a Chagas disease specialist, Dr Anis Rassi Jr. So thanks Dr Rassi for the answer.

The phases of the disease are only 2: acute and chronic. The chronic
phase is divided into: indeterminate form, cardiac form, digestive
form and cardio-digestive form. With the exception of only about 5% of
the patients who right after the acute phase get directly into a
determinate form, all the others get into the indeterminate form. Of
those in the indeterminate form, about 60% will remain indeterminate
all lifelong while about 40% of patients 10 to 30 years later develop
the clinical forms of the disease.
