The death rate is low only because hospital arent overrun and lockdown has worked.
In the centre if Wuhan in the centre of the epidemic the the death rate was significantly higher. Some doctors estimate closer to 40% of those presenting with symptoms. The death rate being directly effected by the number of people you can intubate at any one time. The average age of death or presenting with symptoms also lowers, (we are seeing that in this country with schools already).
You run out of ventilators the death rate very quickly rises. You run out of oxygen the death rate very quickly rises. Those excess deaths from other diseases rises because if your health service doesnt have the resources to treat them. Your medical professionals are become ill, all excess deaths rises.
This isn't a quick disease. 4-6months of unchecked spread it took in Wuhan. People have trouble grasping the impact of those long timeframes. Lockdown now, actually affects hospitalizations mid to end of December. Christmas. They've actually timed lockdown now so Christmas 2020 won't be associated with widescale death and hopefully our medical professionals might get out the hospital some point over the Christmas period.
The only way to avoid ongoing intermittent lockdowns ls is to prevent the disease getting a foothold in the first place (New Zealand) which we didn't do.
Or have enough ventilators for everyone who might need ventilation, which we don't (although it's better than it was).
It's all very easy to stomp our foot and say we want things back the way they were. But thats really all we're doing. It is noticeable that the populations than have done best are the ones where individual rights and freedoms are considered subservient to the needs of the community as a whole.
That's the real lesson
