Chagas disease, or American trypanosomiasis, is a parasitic infection caused by Trypanosoma cruzi, mainly transmitted by blood-feeding insect vectors. It progresses in two phases: an acute phase that is often asymptomatic, followed by a chronic phase that, in some patients, can lead to severe and potentially fatal cardiac or digestive complications. Today, several million people remain infected, primarily in Latin America, although the disease is becoming increasingly global due to migration and environmental changes.
