 Studies suggest antiparasitic treatment leads to parasitological cure in more than 90 % of infants but only about 60 – 85 % of adults treated in the first year of acute phase Chagas disease . Children aged six to 12 years with chronic disease have a cure rate of about 60 % with benznidazole . While the rate of cure declines the longer an adult has been infected with Chagas , treatment with benznidazole has been shown to slow the onset of heart disease in adults with chronic Chagas infections .
