I'm pretty sure you know the answer to this. It's been repeated over and over for 6 months.
If cases go up, deaths will go up. Roughly 1% of people die from the virus. That means its not a massive risk for most individuals. And because of the way averages work, for the majority of people it is much, much less than 1% risk. Behaviorally that makes it hard for people, because its a relatively hard jump for humans to make from personal risk to societal risk.
But if we get to a point where we have 100,000 cases per day, as has been analysed was the case at the end of March, and we do nothing, then roughly 1-2 weeks after that we will have about 10,000 people every day needing hospitalization, and about 1-3 weeks after that we will have 1,000 people dying per day. Most of them will be dying in hospital. Hospitals don't have the capacity, particularly the critical care staff, to deal with that many people needing that level of care. That's why we built the nightingale hospitals. You know this.
Now putting it in perspective at that point, roughly 1,600 people die each day in the UK anyway, so it would be about a 60% increase in daily deaths.
But then a few other things come into play.
Although 1,600 people die in the UK each day, not all of them die in hospital.
And remember there is exponentiation growth, and in this scenario we are doing nothing to stop the spread, so if cases double each week then after another week you have 2,000 deaths per day, then 4,000, then 8,000, then 16,000. So we are up to 16,000 deaths every single day, after just another 4 weeks, if we do nothing. Now that is 10 times the number of people who normally die in a day, of all other causes, ongoing and increasing every single day.
Obviously at some point this becomes self limiting, because presumably at some point people start to think that going out at all is a bad idea even if there are no restrictions in place.
Of course all of this affects the availability of things like supply chains, water, electricity etc.
But, as I said, I think you already know this because it has been talked about a lot. So which bit is it that doesn't resonate with you?
