Final answer:
Chagas disease is NOT caused by prions. It is caused by the parasite Trypanosoma cruzi.
Step-by-step explanation:
Prions are infectious agents that cause certain neurodegenerative diseases. They are responsible for diseases like kuru and bovine spongiform encephalopathy (BSE), also known as mad cow disease. However, Chagas disease is NOT caused by prions. Chagas disease is caused by the parasite called Trypanosoma cruzi, which is transmitted to humans through the bite of infected triatomine bugs.
