The mixed public health outcomes of the pandemic call into question the obligations of the International Health Regulations (IHR) (2005) in light of evolving public health knowledge. Accordingly, the IHR seeks to frame public health responses without disrupting international traffic.

Travel restrictions should be based on scientific principles and WHO guidelines. RSI assessments need evidence to know when to restrict movement. While strengthening WHO guidelines to reflect epidemiological data, promote health equity and support global cooperation, revisions to the IHR (2005) should allow flexibility in implementing travel restrictions based on evidence.

The necessity and proportionality of various travel restrictions and standards in national contexts requires further research.
