A single rapid antigen test for Covid-19 upon arrival is as effective as 10 days’ self-isolation in reducing imported cases of Covid-19, the authors of a new study commissioned by a coalition of aviation industry stakeholders have claimed.
Based on the prevalence of Covid-19 in the UK and overseas, and accounting for quarantine compliance, Oxera and Edge Health say their findings suggest a single test would be appropriate for arrivals from countries categorised medium-risk as a consequence of either their Covid caseload or vaccination rate.
These countries, Oxera and Edge believe, could be designated "amber" if the UK government was to press ahead with a traffic light system to categorise risk when international travel resumes.
