  • One challenge is the lack of direct demonstration of transmission events in humans, which limits the understanding of sexual transmission. Another challenge is the ethical and medical constraints of sampling reproductive tissues, which hinders the collection of direct evidence. The paper also identifies the challenge of underreporting of Chagas disease cases, which affects the accuracy of epidemiological studies.
