Ok, so let's talk HERD IMMUNITY
This is an epidemiological concept that describes what happens when enough people are immune to a disease that it can't spread

I.e. if 40% of people get #COVID19, the disease will probably stop depressing by itself (as long add it confers lasting immunity)

Similarly, if enough people self-isolate, or if social distancing reduces the effective reproduction rate low enough, the disease may stop spreading However, this is not herd immunity

Apologies, mistake in the number above It is 1-40%, or 60% who need to be immune for herd immunity given this R0!

Also, good to note that herd immunity requires a LOT of people to get infected If 60% of the population gets sick, and 1% of the cases die, that's 0.6% of THE ENTIRE POPULATION dead In the UK, that's millions of people

It's not the total that matters as much as limiting the rate of spread to limit the number of concurrent infections. Otherwise the hospitals will be overwhelmed and more people will fdie from treatment capacity limits.
