I see lots of guesses about the decline in the U.K. usually one of: 1. Schools closing (~2 weeks earlier in Scotland than England) 2. Euros [football tournament] ending (Scotland fell out ~2 weeks earlier than England) 3. Hot weather (leading to events outdoors or more ventilation or less going out or something else bad for the virus) 4. The “pingdemic” where the contact-tracing app tells many people to self-isolate 5. The end of a big burst of weddings scheduled when restrictions were due to ease 6. Herd immunity 7. Maybe lots of people went on holiday and mostly kept to themselves. 8. Some statistical anomaly hiding case numbers that are not falling (eg fewer tests->fewer total positive cases) I don’t really believe 7 or 8 and everything else feels too unsupported. Perhaps time will tell what the cause is but I think I am weakly optimistic about current trends. We shall have to see.
