Quasi-experimental evaluation of national border closures on COVID-19 transmission.

ABSTRACT: With over 200 pandemic threats emerging every year, the efficacy of closing national borders to control the transmission of disease in the first months of a pandemic remains a critically important question. Previous studies offer conflicting evidence for the potential effects of these closures on COVID-19 transmission and no study has yet empirically evaluated the global impact of border closures using quasi-experimental methods and real-world data. We triangulate results from interrupted time-series analysis, meta-regression, coarsened exact matching, and an extensive series of robustness checks to evaluate the effect of 166 countries' national border closures on the global transmission of COVID-19. Total border closures banning non-essential travel from all countries and (to a lesser ext
