I agree with others re the limitations of the data and the frustration with lack of information about routes of transmission.
I still believe the majority of cases are in hospitals, hospices and other institutions, driven by the need for health and social care services to be delivered and other essential services (food distribution and processing for e.g.) but it spreads into the community through these workers.
Track and trace is limited (not identifying contacts soon enough but also because of assuming the contagion period is 48 hours before symptoms start or a positive test) and people are often given no practical support to isolate or told to get into work even if their children are isolating because this is not a direct contact.
People meeting for a coffee or collecting takeaway or whatever small thing makes their life bearable isn't going to be a spreading event IMO
