We examine the role of Venezuelan forced migration on the propagation of 15 infectious diseases in Colombia. For this purpose, we use rich municipal-monthly panel data. We exploit the fact that municipalities closer to the main migration entry points have a disproportionate exposure to infected migrants when the cumulative migration flows increase. We find that higher refugee inflows are associated with increments in the incidence of vaccine-preventable diseases, such as chickenpox and tuberculosis, as well as sexually transmitted diseases, namely syphilis. However, we find no significant effects of migration on the propagation of vector-borne diseases. Contact with infected migrants upon arrival seems to be the main driving mechanism.

我们研究了委内瑞拉强迫移民对哥伦比亚 15 种传染病传播的作用。为此，我们使用了丰富的市政月面板数据。我们利用这样一个事实，即当累积移民流量增加时，靠近主要移民入口点的市政当局会不成比例地接触受感染的移民。我们发现，更多的难民流入与疫苗可预防疾病（如水痘和肺结核）以及性传播疾病（即梅毒）的发病率增加有关。然而，我们发现迁移对媒介传播疾病的传播没有显着影响。抵达后与受感染的移民接触似乎是主要的驱动机制。
