While an estimated 6-7 million people worldwide carry Chagas disease infection, a new study in The Lancet Regional Health – Americas reveals that surveillance infrastructure in endemic countries remains inadequate. Researchers examining Bolivia and Paraguay documented critical gaps in routine data management systems across multiple healthcare levels, compromising the ability to monitor disease burden and control intervention effectiveness.
The majority of Chagas disease cases concentrate in Latin America, with particular burden in rural and impoverished communities. Despite the substantial global health impact—affecting 75 million people at risk—health information systems show persistent weaknesses in data collection and utilization. These findings highlight a troubling disconnect between disease burden and surveillance capacity, underscoring why targeted health system investments are essential for effective disease control.
