Chagas Disease

Chagas’ Disease

(also called American trypanosomiasis), a transmissible parasitic disease of humans and animals caused by trypanosomes. The disease was described in 1909 in Brazil (state of Minas Gerais) by the physician C. Chagas. It occurs in Central and South America, chiefly among the poorest strata of the population, who live in dwellings infested by transmitters of the disease (bloodsucking hemipterous insects, mainly triatomids). Humans and wild and domestic animals suffering from Chagas’ disease are the sources of infection.

Infection occurs when the causative agent, together with insect feces, enters injured skin or the mucous membranes of the eyes, nose, and mouth. The main symptoms are fever and enlargement of the lymph nodes in the acute stage, with involvement of the heart and gastrointestinal tract when the disease becomes chronic. The main methods for controlling Chagas’ disease are improvement of social and living conditions of the people, disinsectization, and destruction of infected animals.

South A·mer·i·can try·pan·o·so·mi·a·sis

trypanosomiasis caused by Trypanosoma (or Schizotrypanum) cruzi and transmitted by certain species of reduviid (triatomine) bugs. In its acute form, it is seen most frequently in young children, with swelling of the skin at the site of entry, most often the face, and regional lymph node enlargement; in its chronic form it can assume several aspects, commonly cardiomyopathy, but megacolon and megaesophagus also occur; natural reservoirs include dogs, armadillos, rodents, and other domestic, domiciliated, and wild mammals. Synonym(s): Chagas disease, Chagas-Cruz disease, Cruz trypanosomiasis

Chagas disease

(shag'as) [Carlos Ribeiro Justiniano Chagas, Brazilian physician, 1879–1934] A bloodborne disease caused by Trypanosoma cruzi and transmitted by the biting of a reduviid bug. It is characterized by fever, lymphadenopathy, hepatosplenomegaly, and facial edema. Chronic cases may be mild or asymptomatic, or may be accompanied by myocarditis, cardiomyopathy, megaesophagus, megacolon, or death.

Etiology

Chagas disease may be transmitted from person-to-person by needlestick injury, transfusion, organ donation, or during childbirth.
