The first image shows an acute infection with swelling of the right eye. This is a chagoma. He shows Romana's sign: unilateral periorbital edema, conjunctivitis, and preauricular lymphadenitis. The second image shows the vector insect Triatoma infestans, also known as the Kissing Bug. The third image shows Trypanosoma cruzi parasites, stained with a Giemsa stain. This is the pathogen of Chagas' disease or American trypanosomiasis. Chronic infection with Chagas' disease can lead to cardiomyopathy.
