Abstract
During outbreaks of diseases like cholera, HIV/AIDS, H1N1, and Ebola, governments often impose international border restrictions (for example, quarantines, entry restrictions, and import restrictions) that disrupt the economy without stopping the spread of disease. During COVID-19, international travel restrictions were ubiquitous despite initial World Health Organization recommendations against such measures because of their limited public health benefit and the potential for imposing a range of harms. Why did governments adopt these measures? This article argues and finds evidence that governments use international border restrictions as security theatre: ‘measures that provide not security, but a sense of it’. Quantitative analysis of original data on states’ first border restrictions during the pandemic suggests that behaviour was not just driven by the risk of COVID-19 spread. Instead, nationalist governments, which are likely to be attracted to policies associating disease with foreigners, were more likely to impose border restrictions, did so more quickly, and adopted domestic measures more slowly. A case study of the US further illustrates the security theatre logic. The findings imply that overcoming or redirecting governments’ attraction to security theatre could promote international cooperation during global health emergencies.
