The challenge is that this disease passes on without people knowing. I have seen the challenge of older people trying to stay away from and stay safe from the continuing spread. In the United States of America, we saw that, at first, the increase in rates was among younger people and then it spread and the hospitalisation rate went up and then the number of deaths went up. Unfortunately, we are seeing a similar pattern on parts of the continent. I understand where my right hon. Friend is coming from. The goal is to have as little intervention, as targeted intervention, as possible, subject to keeping the virus under control. That is what we are trying to do. Essentially, we want to protect the ability of schools to go back and to make sure that we get the economy going as much as possible. These localised interventions, whether through test and trace to the individuals who have tested positive or to a local area where there is an outbreak, is the approach that we propose.
