I am delighted that the Secretary of State is so keen on data. My local clinical commissioning group tells me that it is still not getting the right data to GPs—it is quite clunky—and I think it is right in saying that GPs can see comorbidities, so it is particularly important that they get data about people who have been tested. We currently have an outbreak in the north of my borough and although we have the postcode data, we do not yet have the full address data, which is isolated to households. If we can get that very precise location, it will prevent a local lockdown. Surely the track-and-tracers are getting that data; can they get it to local authorities so that we can handle this situation locally?
