The Chagas disease - An infectious parasitic disease found only in parts of South nand Central America that is spread by insects commonly called cone-nosed or assassin bugs.
The parasites live in the bloodstream and can affect the heart, intestines, and nervous system. Symptoms include swelling of the lymph nodes and fever. Long-term complications include damage to the heart. The drug nifurtimox kills the parasites in the blood but has unpleasant side effects.
