64% of severe infection at one point were acquired in hospitals - that point being December 2020. Again, whilst there were stringent lockdown measures in place. The paper doesn’t specify whether this percentage is on a specific day, a rolling 7-day average, a rolling 30 days, etc.
Unfortunately as a non-subscriber I can’t access the Teegraph article. However, the Guardian article makes for interesting reading and again tallies with the idea that a single week in December saw the peaking of hospital-based infection, before beginning to drop again i.e. when there is more social mixing the percentage acquired in hospital reduces - suppose that’s not groundbreaking. Estimates are that between August and February there were 39,000 people likely to have been infected in English hospitals; a not insignificant number but making up a tiny proportion of infections within that timeframe.
Forgive me, but I genuinely don’t understand the point you are trying to make with this. The data you provide basically proves that lockdown measures work for reducing community-based infection, but I know you ain’t arguing for measures to be extended/reimposed!
