I am pleased to bring this wide-ranging debate to a close. We are now almost two years on from when this virus first emerged in Wuhan. Since then, science and disease have been locked in a battle for ascendancy. For the last year, science has been on top as the global effort on vaccines has dramatically reduced the risk of hospitalisation and death for those who catch covid-19, but we know from the history of previous diseases that they mutate and change, so that vaccinations and treatments become less effective. That is why only one disease, smallpox, has been eradicated, although we are close to eliminating polio, too.
The virus is fighting back, and we must respond. To those who say that the regulations we have debated�the reintroduction of face coverings in some settings and self-isolation requirements for close contacts�are an imposition on our liberties, I agree, but they are a necessary imposition to slow the spread of a new variant and allow science to catch up. However, there is a balance to be struck. Too many restrictions have a crippling effect on social and economic life, as well as adding to the burden of mental illness. For those who say that the regulations we have debated are not enough, I say that they will buy us time to understand this new variant better. That is why they will be reviewed in three weeks� time.
We will continue to closely monitor all the emerging data on the new variant. We have committed to review all of the measures in three weeks� time, ahead of the face coverings regulations expiring. Restrictions will not be in place any longer than necessary. We do need to learn to live with this virus, but it is right, in the face of a potential threat, to take balanced and proportionate measures, and we will continue to closely monitor all the emerging data on the new variant. Overall, I would like to reiterate that this will be a moving picture over the coming weeks. We will get a better idea of its nature in the next couple of weeks. Its transmission advantage, vaccine escape and severity of infection are some of the things we are looking at as we observe how the variant develops in southern Africa and the rest of the world, too. Alongside that, the scientists will continue to study it in the lab, but it will be several weeks before we get a clear picture. The most important thing is that the
world keeps sharing information and findings as new cases emerge. I thank my hon. Friend the Member for Christchurch (Sir Christopher Chope) for raising an inconsistency in our explanatory memorandum at paragraph 12.3. For clarity, I will read out the section as it was intended:
�Furthermore, the policy will be supported by a communications campaign that will make clear that some people are exempt from these regulations and people should not be challenged by members of the public for not wearing the face regulation.�
I trust that that reassures my hon. Friend on the matter and on the seriousness with which the Government take supporting those who are exempt from these requirements. I will be working with officials to rectify this.
With respect to omicron-positive cases, NHS Test and Trace will work with the positive case and/or their parent to identify close contacts. Contacts from a school setting will only be traced by NHS Test and Trace where the positive case and/or their parents specifically identify the individual as being a close contact. There is likely to be a small number of individuals who will be most at risk of contracting covid-19 due to the nature of the close contact. I reiterate that the direct contact will be by NHS Test and Trace, rather than via the covid app.
My hon. Friend the Member for Winchester (Steve Brine) and my right hon. Friend the Member for South West Wiltshire (Dr Murrison) talked about suspected cases. My right hon. Friend hit the nail on the head: many of the laboratories processing the PCR tests will be able to test for the S-gene dropout and that will give a very good indication of cases of the omicron variant. While it does not provide 100% confirmation, we can get that information very quickly and at the same time the test result is reported and that is ahead of any genomic sequencing.
