One thing that I rarely see mentioned is the context for a "herd immunity" style strategy of doing nothing at all about the pandemic In particular, how long will it take?

Well, assuming a lowered herd immunity threshold of 40% to account for heterogeneity (this is quite low, but not entirely unreasonable), we need a further ~23 million people infected for things to go back to "normal"

At 100,000 infections per day, that's 230 days, or about 33 weeks at this level of infection to reach a stable state where the epidemic is no longer spreading

Now, obviously, epidemics don't work quite like that. Without restrictions, we would expect the number of new infections to grow which would reduce the total time it takes to infect 40% of Britain

Even so, I think it's worthwhile to note that the time period to get back to "normal" if you relax all restrictions is not tomorrow, nor next week, but in all likelihood months or even years
