By the end of 2020, more than 500,000 migrants from Central America, Haiti, Africa, and Asia sought asylum along the US-Mexico border despite COVID-19-related travel restrictions and public health measures. A scoping review was conducted to understand the role of COVID-19-related policies on irregular migration flows through Central America and Mexico and to examine the experiences of asylum seekers traversing this region. Peer-reviewed literature, policy briefs, and commentaries were screened for inclusion, resulting in 33 documents selected for this review. This review identified three dominant themes: border closures due to multiple national migration policies, delays in asylum procedures, and increased risks to migrant wellbeing. This article argues that border closures were a punitive policy measure to deter irregular migration during the COVID-19 pandemic. Implications for future research and policy include prioritizing the health needs of asylum seekers and advocating the appropriateness and effectiveness of immigration and public health policy.
