A single on-arrival antigen take a look at is as efficient as a ten-day self-isolation interval in decreasing imported circumstances of Covid-19, new modelling has argued.

Primarily based on prevalence charges at residence and overseas and accounting for quarantine compliance, Oxera and Edge Well being discover {that a} single fast antigen take a look at can be acceptable for arrivals from the vast majority of nations categorised as medium danger, the place there are medium caseloads or decrease vaccination charges.

Such nations could possibly be designated as ‘amber’ if the UK authorities applies a site visitors mild system for international journey to classify danger.

In proof submitted to the worldwide journey taskforce this week, most of the fast, cheap and efficient antigen assessments are proven to cut back the variety of infectious days of a world arrival by 63 per cent.

Which means the danger of neighborhood transmission from a single take a look at is comparable, if no more efficient, to a ten-day quarantine interval with no testing, which screens 62 per cent of infectious days and was the UK border coverage for nations with out journey corridors till January 18th.

The brand new findings reveal how the federal government’s proof base has underestimated the effectiveness of a single antigen take a look at, which SAGE beforehand reported would display solely 11 per cent of infectious travellers.

For higher-risk nations, a two-test technique could possibly be a viable possibility as a part of a risk-based framework to soundly reopen worldwide journey this summer season.

Utilizing a 72-hour pre-departure antigen take a look at and three-day quarantine with PCR take a look at, 87 per cent of doubtless infectious days are screened – only one proportion level decrease than a dual-PCR take a look at.

Crucially, the brand new proof demonstrates that the two-test strategy delivers efficient ranges of screening, whereas guaranteeing that the UK can simply monitor and genome sequence the assessments of passengers, mitigating the danger of importing variants of concern.

Michele Granatstein, companion at Oxera, mentioned: “The final word objective for governments have to be to return to frictionless journey between nations which might be thought-about lower-risk.

“The vaccine roll-out, mixed with internationally agreed requirements on digital options to proof Covid-status certification, can be intrinsic to that, however individuals ought to be capable to journey safely, with or with out a vaccine.”

Virgin Atlantic chief government, Shai Weiss, welcomed the information.

He mentioned: “We imagine that worldwide journey can safely restart at scale, utilizing a risk-based, phased easing of testing necessities and border restrictions, that follows the scientific proof.

“In parallel to the world-leading UK vaccination programme, seamless journey between the UK and decrease danger nations – such because the US, Caribbean and Israel – should stay the target, enabling the free motion of individuals and items which might be important to the financial restoration.

“When utilized to the federal government’s proposed site visitors mild framework, this new modelling by Oxera and Edge Well being demonstrates how sturdy and proportionate testing methods will be utilized to amber and pink nations, defending public well being by decreasing imported infections and capturing variants of concern early by way of genomic sequencing.”
