A recent Global Strategy Lab study assessed COVID-19 border closures from three years ago. Extreme shutdowns briefly slowed transmission, while targeted closures had little impact. Some targeted closures may now be considered illegal under international law, according to the lead author. Border closures should be a last resort, with global coordination by the World Health Organization for optimal effectiveness.

Global Strategy Lab Director Steven J. Hoffman has accepted the role of Vice-President of Data & Surveillance with the Public Health Agency of Canada. In this new role he will focus on the modernization of Canada’s public health data architecture, surveillance systems, and risk assessment capabilities. This work will involve expanding the size of PHAC’s data and surveillance branch to deliver on Federal Budget 2022’s unprecedented $436 million investment in the agency’s “detect, understand and act” framework.
