40% seems high, although my reading certainly directs between 10 and 20%. The more stress on a system the more likely hospital acquired covid is to occur unfortunately. Infection control is much easier with empty beds, space and high staffing levels I imagine.Around 40% of cases 'in hospital' @Redwurzel are patients who go to hospital for something else and contract covid in the hospital. Your neighbour is not alone.
The economic devastation is coming like a tsunami and it really worries me. I hope you all cope ok.
This is one of the big risks of opening up while community transmission and hospital capacity is high. A single vaccination provides some protection, but if prevalence is high and your immunity is compromised by other illness you are still at risk. Hopefully the second wave of vaccinations will be as successful as the first, the 25% of population previously infected is correct and severe cases fall with this.
Then you can isolate better and target resources better to keep those most at risk/ vulnerability safe.
I hope they do use the numbers to guide decisions being made, as not getting control now could well lead to another repeat of last year when it is the last thing we need.
