Details

The UK Health Security Agency (UKHSA), in partnership with devolved administrations, has developed a dynamic risk assessment methodology to inform ministerial decisions on red and green list countries and the associated border measures against the risks of importing cases of SARS-CoV-2 and its variants.

Available and relevant sources of information for each country or territory are used to provide an overall assessment on:

  • genomic surveillance capability

  • SARS-CoV-2 transmission risk

  • variant of concern (VOC) transmission risk

Decisions are taken by ministers informed by evidence, including analysis by UKHSA as well as other relevant public health factors.

A summary of key data used by UKHSA to inform the latest round of assessments is shown in the tables.
