Governments around the world have adopted significant migration management measures to try to contain and halt the spread of COVID-19. Border closures, travel restrictions, prohibitions on arrivals from certain areas, and heightened screening have been among the leading policy responses, initially to try to block COVID-19 from crossing borders and later, as the pandemic became a global one, as part of a raft of mobility restrictions seeking to mitigate further spread. The success of these restrictions in stemming the initial breakout of public health threats across international borders as well as their role in mitigating “community spread” within affected states is a matter of dispute. More clear, however, is that internal measures—such as business closures and “lockdown” orders—are likely to be borne disproportionately by the most vulnerable, including refugees, unauthorized populations, and other immigrants.
