摘要

自 2014 年以来，数百万委内瑞拉人逃往邻国。巴西与委内瑞拉边境只有一个陆路口岸（帕卡雷马），而巴西的高速公路系统限制了移民只能走一条穿越亚马逊近 1000 公里的路线。将这一事件作为准随机处理，我们发现难民移民增加了帕卡莱马的疟疾发病率，但这仅限于委内瑞拉国籍的个人。我们没有发现难民迁徙对帕卡莱马市或主要难民迁徙路线沿线其他城市的巴西人有任何影响。因此，我们否定了委内瑞拉难民增加了本地居民疟疾发病风险的假设。

The effect of mass migration on disease transmission: Evidence from the Venezuelan refugee crisis

Since 2014, millions of Venezuelans have fled to neighboring countries. There is only one accessible land crossing along the Brazil–Venezuela border (Pacaraima) and the Brazilian highway system limits migrants to one route through the Amazon for almost 1000 km. Using this event as a quasi-random treatment, we find that refugee migration increased malaria incidence in Pacaraima, but this was limited to individuals of Venezuelan nationality. We find no effect on Brazilians in Pacaraima or in other municipalities along the main refugee migration route. We therefore reject the hypothesis that Venezuelan refugees increased the risk of malaria among native residents.
