In Brazil, mortality from Chagas disease occurs even in regions classified as free of vector transmission. Because death rates refer to residents, and considering that a huge migratory movement has occurred inside the country, this study was intended to quantify the contribution of Brazilian internal migration to overall mortality from Chagas disease, from 1981 to 1998. If the PAHO Southern Cone Initiative actually achieved its objectives, one could expect declining death rates and increasing age at death from this cause. The results showed that out of 68,936 deaths in Brazilians with known birthplace, 32,369 (32%) occurred in people born in States other than those of their current residence (range: from 0.3% in Rio Grande do Sul to 100% in Roraima and Amapá). Most (67%) of the deaths in migrants occurred in individuals born in the States of Minas Gerais (51%) and Bahia (16%). Death rates in residents showed a consistent decline in the Southeast, South, and Central West of the country, but not in the Northeast and North, where median age at death was the lowest.
在巴西，即使在被归类为无媒介传播的地区，恰加斯病导致的死亡率依然存在。由于死亡率是针对居民而言的，并且考虑到巴西国内发生了大规模的人口迁移，本研究旨在量化1981年至1998年期间巴西国内移民对恰加斯病总体死亡率的影响。如果泛美卫生组织南锥体倡议真的实现了其目标，那么可以预期因该病因导致的死亡率会下降，死亡年龄会上升。结果显示，在出生地已知的68936名巴西死亡者中，有32369人（32%）出生于其当前居住地以外的州（范围：从南里奥格兰德州的0.3%到罗赖马州和阿马帕州的100%）。大多数（67%）移民死亡者出生于米纳斯吉拉斯州（51%）和巴伊亚州（16%）。该国东南部、南部和中西部地区居民的死亡率持续下降，但东北部和北部并非如此，这两个地区的死亡年龄中位数是最低的。
