Chagas Disease
Infection with the protozoan parasite TRYPANOSOMA CRUZI, a form of TRYPANOSOMIASIS endemic in Central and South America. It is named after the Brazilian physician Carlos Chagas, who discovered the parasite. Infection by the parasite (positive serologic result only) is distinguished from the clinical manifestations that develop years later, such as destruction of PARASYMPATHETIC GANGLIA; CHAGAS CARDIOMYOPATHY; and dysfunction of the ESOPHAGUS or COLON.
About the B57 Code Range
Chagas' disease is an infection caused by a protozoan parasite called Trypanosoma cruzi.
The acute branches distinguish cases with heart involvement from those without it. The chronic branches separate heart, digestive system, nervous system, and other organ involvement.
The digestive branch distinguishes unspecified involvement, B57.31 for an enlarged esophagus, B57.32 for an enlarged colon, and other involvement. The nervous system branch separates unspecified and other involvement from meningitis and meningoencephalitis, conditions named in B57.41 and B57.42.
