Morbidity during the acute phase of Chagas disease is more pronounced in children than in adults. The gastrointestinal and cardiac manifestations of chronic T cruzi infection become apparent many years or even decades after initial infection and thus occur almost exclusively in adults. However, the lifetime risk for the development of such symptoms in chronically infected persons is only 10%-30%.
