Overview

On physical examination, Chagas disease may manifest with fever, tachycardia, cardiac rhythm abnormalities, hepatosplenomegaly, and lymphadenopathy. Romaña’s sign, a classical sign of Chagas disease, is characterized by eyelid sweilling at the site of parasitic entry. Other signs on physical examination are usually due to either cardiac or GI manifestations of the disease.
