Perceptions of the ethical permissibility of strict travel restrictions to mitigate transmission of SARS-CoV-2.

Although there has been extensive exploration of public opinion surrounding many non-pharmaceutical interventions (NPIs) aimed at mitigating transmission of SARS-CoV-2 (e.g. mask-wearing and social distancing), there has been less discussion of the public's perception of the ethical appropriateness other NPIs. This paper presents the results of a survey of U.S. adults' opinions of the ethical permissibility of both state-to-state and international travel restrictions to mitigate transmission of SARS-CoV-2. Our research revealed overall high agreement with the ethical permissibility of both state-to-state and international travel restrictions, though we saw significant difference across political party affiliation and conservative/liberal ideologies. Other factors associated with agreement with state-to-state travel restrictions included increasing education, increasing income, and both high and low commitment altruism. When considering international travel restrictions, income, education, and low commitment altruism were associated with increased agreement with the ethical permissibility of international travel restrictions. Ethical analysis and implications are explored.
