But the Covid-19 death numbers are growing exponentially. If James Arthur's 1.24 increase per day persists for 23 days, there will be have been as many Civd-19 deaths in those 23 days as 216k respiratory disease deaths that the US has in a year.
I can understand the general public having little comprehension of what
"exponential" means, but I am surprised that it seems to have been
ignored or misunderstood by those who should know better. Stating
figures about deaths from other causes misses the point entirely; they
are known causes, understood, and changes in the death rate - whether
up, down, or constant, is explicable, linear, and usually minor..
One other point is misunderstood. We talk about treatment by intensive
care and use of ventilators. The problem is those are finite sources,
maybe increasing slightly as time goes on, but the exponential growth of
coronavirus infections will drown those increases. If there are 10000
ventilators today, and 20000 next week, it won't help much if there are
10000 cases of Covid-19 today and 100000 next week.
I understand exponential growth. There would be 1 million the
following week, then 10 million the next week, and 100 billion cases a
month after that. The US will hit 100 billion cases around the end of
April.
100 billion's manageable. In newsmath, those could still be funded
(a million dollars each) from Mike Bloomberg's campaign spending.
The problem happens a month later, when there'll be 8,128.5494322736
times as many cases. California's brilliant governor will need to
find another 19,543 hospital beds.

I'm mostly through re-reading Barry's influenza book. The 1918
influenza was immensely worse than this thing. Over 4000 people died
per day in Philadelphia. Europeans seemed to have some immunity, and
some native villages and islands were wiped out entirely; no
survivors.
In any locality, the time from first case to burnout was about 6
weeks, more like 4 weeks at crowded army bases. It grew as a
bell-shaped curve with the tail chopped off, exponential start and a
very abrupt end.
I can, maybe optimistically, imagine that sort of curve in the data
from a lot of countries now. Initial fast growth but now flat or
declining.
There's an exceptionally good presentation of the reasons for the
Australian approach, by someone who "gets" both the biology and the
maths, here:
https://iser.med.unsw.edu.au/blog/busting-myths-about-covid-19-herd-immunity-children-and-lives-vs-jobs
Unfortunately the USA has probably squandered the opportunity to take
this approach, so will have to be shunned by the rest of the world for
years while a million or more die in repeated cyclic outbreaks, until an
effective vaccine controls the outbreak. It's a catastrophic failure of
governance.

Crunching the numbers from worldometers.info today,
cases | deaths | infection rate (ppm)
--------+--------+---------------------
Europe 470,388 | 32,636 | 1,385
EU 399,188 | 29,132 | 1,176
---------------+--------+---------------------
USA 200,289 | 4,394 | 605
Stop annoying people with data.
Sooorrrrrryyyyy.
Clifford's right, it's here, and it's growing. But we didn't
start it.
Perhaps we should've cut off travel from Europe earlier.
