My Lords, over the past few months, the Government have made a concerted effort to bring forth a sense of normality across the country with the easing of restrictions, while maintaining caution with regard to this deadly virus, which clearly has a long way to run. These regulations are a key part of this dual-track effort, significantly reducing the burden of self-isolation while protecting society from the threat of contagion. The main focus of the regs is the isolation protocols, so I begin by reflecting on the crucial role that contact tracing and self-isolation play in fighting the virus.
Since it was established in May 2020, NHS Test and Trace has contacted more than 15 million people who have tested positive for Covid-19 or who have been in contact with a positive case. Tracing—the bedrock of any public health intervention—has improved substantially over the last several months. In October 2020, 60% of close contacts were being reached. In comparison, over the period from 26 August to 1 September, 87.3% of positive cases transferred to NHS Test and Trace were reached, as have 89.5% of their contacts where usable contact details were provided. That is a remarkable achievement.
The public realise the importance of isolation. July’s ONS statistics that show 79% of positive cases reported complying with the self-isolation guidance, alongside 89% of close contacts. That is a terrific response from the public and it has proven a vital weapon in our arsenal against the virus.
What is the impact of this massive financial and societal investment? A recent study from PHE, published today and called the Canna model after the idyllic Scottish western isle, which some noble Lords may have visited, shows that from August last year to this April, test, trace and self-isolation activity reduced the transmission of the virus by between 10% and 28%. The PHE research demonstrates that self-isolation helped to bring R below one at crucial times, reducing the duration and impact of lockdown. Over the full period of the study, the Canna model estimates that isolation due to test, trace and isolate policies prevented between 1.2 million and 2 million secondary cases. The NHS Test and Trace service has also enabled us to identify peaks and troughs in case rates, supporting decisions on when restrictions should be tightened or could be eased.
We recognise that none of this has been easy. The requirement to isolate creates enormous challenges for individuals and their families across the country. A study in March 2021 by the BMJ concluded that offering financial and practical support to individuals who needed to self-isolate would likely improve compliance. We support that view. Since September last year, we have provided councils with £280 million to issue support payments to those who may face financial hardships because of self-isolation. We have also made up to £100 million available between March and September this year for councils to offer practical and emotional support to some of the most vulnerable in our communities, covering over 200,000 people. It is right, though, that we sought to reduce the burden of self-isolation at the earliest opportunity.
