Chagas' disease

Chagas' disease
a disease caused by the protozoan parasite Trypanosoma cruzi. It is transmitted to humans when the trypanosomes, present in the faeces of nocturnal bloodsucking reduviid bugs, come into contact with wounds and scratches on the skin or the delicate internal tissues of the nose and mouth. The presence of the parasite in the heart muscles and central nervous system results in serious inflammation and lesions, which can prove fatal. The disease, limited to poor rural areas of South and Central America, is especially prevalent in children and young adults. It may be treated with nifurtimox. See also trypanosomiasis. [C. Chagas (1879–1934), Brazilian physician]
