Interesting numbers from Sir Patrick Vallance based on serology tests:

~10% of Londoners thought to have had coronavirus

~4% for rest of UK

That implies ~3m total across UK from population of 66m

At its peak he added it was doubling every 3-4 days. If you conservatively estimate ~2m infections came pre-lockdown that means if we’d waited another fortnight roughly half the population would have been infected.

Going the other way they think we’re now down to ~130,000 infections UK wide with that number roughly halfing every two weeks.

Would take two months with existing measures to get that down to around 8,000.
