1. The data source is the Daily publication of Covid-19 admissions and bed occupancy.
2. Hospital acquired cases have been calculated by subtracting measure 3 (Estimate of new admissions to hospital from the community) from measure 2 (Estimated new hospital cases)
3. A rolling 7-day average of both hospital and community acquired cases has been calculated, so, for example, the value for 7 September is the average for 1-7 September.
