COVID-19, SARS-CoV-2, and Export Controls.

Export controls are intended to prevent the proliferation of materials that could be misused to make biological weapons. They are not intended to stifle critical research and development in the midst of a pandemic. This article explores how and why export controls might apply to severe acute respiratory syndrome coronavirus 2, the virus that causes coronavirus disease 2019. It outlines the taxonomic and genetic factors associated with the current approach to export control lists and discusses how they lead to unnecessary ambiguity. The authors describe ways in which the current export control systems might be revised in the short, medium, and long term, including sequence, disease, and function-based approaches.
