After 111 years of its discovery, Chagas disease remains a major public health challenge in Brazil and in other Latin American countries, reason why it continues to be a relevant topic in discussion panels worldwide. The disease was first described in 1909 by Carlos Justiniano Ribeiro das Chagas after his observations during an expedition to eradicate malaria in the rural areas of the state of Minas Gerais, in the city of Lassance. Carlos Chagas’ magnificent life journey makes him a unique figure in the history of medicine, as he alone described all the stages of a new infectious disease: pathological findings, means of transmission (Triatoma infestans), etiology, clinical manifestations, and epidemiology. For this reason, he was one of the few Brazilians to be nominated for a Nobel Prize, which, unfortunately, he did not win. This issue of the International Journal of Cardiovascular Sciences (IJCS) focuses on Chagas disease and its repercussions on the cardiovascular system.

Carlos Chagas graduated in 1904 in Rio de Janeiro and began his professional life in the city of Niterói as a physician of the Public Hygiene Committee at Santa Isabel Maritime Hospital, after declining Oswaldo Cruz’s invitation to work at Manguinhos. The Maritime Hospital, a beautiful architectural complex () built during the 19th century from an old farm, was considered a reference for the treatment of infectious diseases until the end of the 4th decade of the 20th century. Sailors, immigrants and local residents with bubonic plague, yellow fever or tuberculosis were treated at the institution. In this hospital, the Italian physician Camillo Terni, from the Serum Therapy Institute of Messina, conducted pioneering studies on a plague vaccine (). After working for 1 year at the Maritime Hospital, Chagas left to Manguinhos, where he began his journey to eradicate yellow fever and malaria, which led him to discover the disease caused by the insect known as barbeiro (kissing bug).
