Chris Whitty said today "Majority of people will not get this virus at all. Of those who do, some of them will get the virus without even knowing, with no symptoms. Of those who get symptoms, 80% will get a mild disease, but not bad enough to go to the doctor. An unfortunate minority will go hospital but the majority will shortly leave. It's only a minority who go to ICU and some sadly die."
I don't get the "majority of people will not get this virus part". We've been told the reason for lockdown was that Covid-19 is highly infectious, far worse than anything we normally experience. That being the case what is it about the majority of the population that stops them getting it?
