Recommendation 21

The Government does not seem to have examined the full range of possible measures affecting international travel and considered their additive effect. It is understandable that the Government did not consider it practical or effective to simply restrict flights, not least because of large numbers of British residents seeking to return home. However, the failure to properly consider the possibility of imposing stricter requirements on those arriving—such as mandatory self-isolation, increased screening, targeted testing or enforceable quarantine—was a serious error. In mid- March, the Government had a limited sense of how many infectious people were arriving in the UK, or where they were arriving from, and had limited means of controlling the onward spread of the virus from such cases. In the circumstances, a precautionary approach aimed at continuing suppression of imported cases of the virus should have included more comprehensive measures for passengers arriving from places which had significant numbers of infections.
