On most days, I'm posting about the pandemic on my other blog (and only occasionally on this blog). You should subscribe there if you want to get notifications of these posts.
The good news is that the rate of
increase in new Covid-19 deaths in the US is still slightly declining, but the
bad news is that still leaves us in the range of 900-1,000 deaths a day for the
foreseeable future – since the lower rate of increase is offset by the increase
in the base number itself. And new cases are still bumping around in the same 20-25,000
range that they’ve been in since early April.
What is changing is the state-by-state
numbers. If you look at new deaths yesterday, you find California on top (which
is a relatively new position for them), followed by the usual suspects: New Jersey,
New York, Illinois, Pennsylvania and Massachusetts. But what about new cases? There
we see a different set of actors altogether. California leads those numbers,
too, but they’re followed by Texas, Arizona, Florida, North Carolina and
Georgia in that order.
In other words, with the exception of
California, none of the new case leaders are also new deaths leaders, and vice
versa. The big question becomes: Will these new case leaders become new deaths
leaders 2-3 weeks from now? Or is it possible that those states have figured
out a way to effectively lower the case mortality rate, so that deaths aren’t
anywhere near the level they were when New York and New Jersey were overwhelmed
with cases more than a month ago?
It does seem that the coronavirus gets
slowed down by sunlight and heat, but a caution there is that Arizona is
probably the closest of these new case leaders to having an overwhelmed
hospital system. While they certainly have a lot of sunlight and heat, they don’t
have a lot of humidity, and that may be helping in states like Florida and
Georgia.
But this also illustrates that all
states need to be expanding their testing, contact tracing and isolation
capabilities. A new wave in the fall could be devastating, since it’s pretty
clear Americans aren’t going to go back into lockdown mode – yet in many states
they’ll be less and less tempted to be outside in the fall. The only thing that
can keep that wave from being much worse than the current one is if we can
identify and isolate new cases quickly and trace and isolate their contacts. We
certainly didn’t have that capability when we really needed it in March, April
and early May, which is why we’re now in the position of having temporarily
restrained the coronavirus, but by no means having defeated it.
The
numbers
These
numbers are updated every day, based on reported US Covid-19 deaths the day
before (taken from the Worldometers.info site, where I’ve been getting my
numbers all along). No other variables go into the projected numbers – they are
all projections based on yesterday’s 7-day rate of increase in total Covid-19
deaths, which was 5%.
Note
that the “accuracy” of the projected numbers diminishes greatly after 3-4
weeks. This is because, up until 3-4 weeks, deaths could in theory be predicted
very accurately, if one knew the real number of cases. In other words, the
people who are going to die in the next 3-4 weeks of Covid-19 are already sick
with the disease, even though they may not know it yet. But this means that the
trend in deaths should be some indicator of the level of infection 3-4 weeks
previous.
However,
once we get beyond 3-4 weeks, deaths become more and more dependent on policies
and practices that are put in place – or removed, as is more the case nowadays
- after today (as well as other factors like the widespread availability of an
effective treatment, if not a real “cure”). Yet I still think there’s value in
just trending out the current rate of increase in deaths, since it gives some
indication of what will happen in the near term if there are no significant
intervening changes.
However,
it’s 100% certain that deaths won’t stop at the end of June! They might decline
some more this summer, but Drs. Redfield (CDC head) and Fauci both predict
there will be a new wave of the virus in the fall, and one noted study
said there was a good probability the fall wave would be greater than the one
we’re in now, as happened in the 1918 pandemic.

Red = projected numbers
I. Total
deaths
Total US deaths as of yesterday: 115,140
Increase in deaths since previous day: 981 (vs. 1,053 yesterday)
Percent increase in deaths since previous day: 1% (this number
was 1% yesterday)
Yesterday’s 7-day rate of increase in total deaths: 5% (This number
is used to project deaths in the table above – it was 6% yesterday. There is a 7-day
cycle in deaths, caused by lack of reporting over the weekends from closed
state offices. So this is the only reliable indicator of a trend in deaths, not
the three-day percent increase I used to focus on, and certainly not the
one-day percent increase, which mainly reflects where we are in the 7-day cycle).
II. Total
reported cases
Total US reported cases: 2,066,611
Increase in reported cases since previous day: 20,627
Percent increase in reported cases since yesterday: 1%
Percent increase in reported cases since 7 days previous: 9%
III. Deaths as a percentage of closed cases so far
in the US:
Total Recoveries in US as of yesterday: 808,551
Total Deaths as of yesterday: 115,140
Deaths so far as percentage of closed cases (=deaths + recoveries): 12%
(vs. 13% yesterday)
