there is one further thing to give people confidence, and alaska baroness harding to come in on this,s we can be more targeted in finding those positive cases and finding those positive cases and finding all of the contacts that they may have infected and passed they may have infected and passed the disease on to and therefore use this more targeted approach to be able to control the virus. as a sector of state said earlier, we are extending the eligibility for tests to the under fives. that is really important for our early years children's and schools and the way nhs test and trace will work as it will provide an early warning system for local communities to spot that there may be a growing number of cases in a school and immediate action can be taken. it is notjust that we will be contacting and identifying and isolating everyone very quickly, we will also be able to spot if an outbreak is starting. i think parents across the country can feel really confident that we have got a system that has their back. thanks very much. thanks very much for your question, great to have you here

, the chairof and i am delighted that baroness harding, the chair of nhs improvement, has agreedreached the most perilous moment, where a wrong move could be disastrous. so at this stage, we can go no further than to announce the first careful modification of our measures. step one, in moving towards covid alert level three, a shift in emphasis that we can begin this week. anyone who cannot work from home should be actively encouraged to go to work in sectors that are allowed to be open should indeed be open but are subject to social distancing. these include food production, construction or manufacturing, logistics, distribution, scientific research and to support this, to explain this again, we are publishing guidance as to businesses on how to make these workplaces covid are safe and secure. people who are able to work from home, as we have continually said, should do so. people who cannot work from home should talk to their employers about returning this week and the difficulties they may or may not have. anyone with covid symptoms obviously, or in a household where someone e
