> some of the major causes of the large death toll...

Wrong. The major cause is that the number of people getting sick at once was much higher than the infrastructure can handle. That's what other governments saw and now try to avoid with the lockdowns.

This was made 10 days ago by the Italian biotech Association it's the number of new cases and deaths per week (red), compared with the number of cases per week at the peak of the "normal" flu (blue):

It can happen everywhere if the growth continues, simply because nothing can cope with fast exponential growth. At the moment, wherever it is uncontrolled, it's around 3 days to double. Sounds like small numbers, just 2 and 3? That gives however a thousandfold growth in 30 days: everybody working with computers should be very familiar with the equation 2^10 = 1024 (it's 2^(30/3) == 2^10 == 1024, 30 being the number of days for the projection, 3 the doubling time and 2 the doubling itself).

Nobody has thousandfold more hospital beds and doctors ready, even less a million times more, which is the two month's growth.

Discussing other factors without first admitting the major one is obviously biased.



Thank you so much for explaining exponential growth to me.

And in a few additional months, we will need more ICU beds than the number of atoms in the universe.

Infection rates are already significant, there just aren't enough people to sustain two months' growth.

This is wrong, of course there are enough people for this to grow for months even with no containment efforts.

That model is 10 days old, and already out of date. Look at the one they've released yesterday.

Again, these models are not robust to minor changes in their assumptions.


> there just aren't enough people to sustain two months' growth

It can be simply calculated: it is expected that without measures the growth to 70% of population would be continuous (very approximately, the end phase wouldn't, we're estimating the limit). So the target is 6e9 people. If we assume that 4/5ths are the people who remain undetected by our current sampling, we want to know the growth between the current known infected and the target which is then 1.26e9 people. Currently known are 0.5 million infected. So the fastest end of growth phase would be just: 2520 times or around 2^11=2048 == just 11 times 3 day doubling time, or 33 days.

The growth will surely not be always exactly 3 days however, so it will be slower, but still not less dramatic, because the resources are many, many times smaller, in the poorer countries many tens of times smaller.

In short it can be very, very bad, and that will be much longer than just a month, just not the exact growth as now.

See the papers from Imperial College London for the exact shapes of the curves and the examples of their speed and growth.

The last one is from today.
