摘要

American Trypanosomiasis, known as Chagas disease, was discovered in 1909 under peculiar circumstances: its discoverer, Carlos Chagas, was sent to a small village of Central Brazil to carry out an anti-malaria campaign when the came across a blood sucking inset-the vector for the parasite infec- tion. He had been alerted to the coincidence of peculiar symptoms and the presence of this insect in the wood and earth dwellings of the region.
