Post #761: This is what absence of leadership looks like: Dinosaurs

Notice, I’m not saying “intelligent leadership”.  I’m not even saying “effective leadership”.  Just “leadership”.

This brings together all my “school of hard knocks” posts.  And related.  And boils down to dinosaurs.  We, in the US, have become dinosaurs.  Ponderous, slow, fundamentally stupid — dinosaurs.

Recall that, three months+ ago, I, a no-credentials blogger (eh, well, Ph.D. economist), talked about the German use of pooled testing for COVID-19, in a math-oriented post (Post #605).

That’s German, as in Germany, the country.  The country that is succeeding in dealing with COVID-19.

Three.  @#$(ing.  Months.

And today, we find out that the US FDA has issued an “emergency” authorization to allow some (not all, but some) US labs to do something like what the Germans were doing three months ago.

You do have to wonder what their definition of “emergency” is.

Not stupid enough for you yet?  Let’s look at some direct quotes:

FDA Commissioner Dr. Stephen Hahn said in the statement. “Sample pooling becomes especially important as infection rates decline and we begin testing larger portions of the population.”

Yeah, that’s really what’s key right now.  We really have to be looking forward to the point where infection rates decline.

Ah, let’s just finish this with one final quote:

“Quest said in a statement it expects to deploy the testing technique at two of its laboratories by the end of next week, and additional laboratories will follow.”

Two laboratories.  End of next week.

For those of you who have no professional interest in health care, Quest is, (I think) the largest laboratory services provider in the USA. If they aren’t #1, then they are #2.

And, maybe, two of their labs, next week, might be set up for this.

Better watch out.   I hear there’s an ice age coming.

See, the thing is, bureaucracies, in and of themselves, may eventually get to the right answers.  But bureaucracies are, by their nature, ponderously slow.

That’s why you need leadership.  Something that countries outside the US have had, to varying degrees.

But absent that, the you get what we’re getting.  Eventually, we’ll probably get something close to the right answers to whatever questions actually got asked.

And that’s our COVID-19 response, in a leadership vacuum.

Post #760: Have we stopped being stupid yet?

Have we stopped being stupid yet?  In the US, regarding COVID-19?

Oh, heck no. 

The only school that’s still fully in session is the school of hard knocks.   And that one’s doing a bang-up business.

Post #759: Another 1000-case day in Virginia

My standard graphs, updated to today (7/17/2020), are below.

At this point, it does not look like they are going to get exponential case growth in the Hampton Roads area.  But it may be too soon to tell.  As of today, it just looks like they went from a steady 300 new cases a day in the early-reopening portions of Virginia, to 800 new cases a day.

Otherwise, the story remains unchanged.  The late-reopening areas are doing OK.  Most of the state outside of the Hampton Roads area, mostly ditto.  Hampton Roads are, not so much.

Oddly, Vienna (22180) picked up 11 new cases last week, which is quite a bit higher than rate observed for the past few weeks.

Virginia (blue) versus Fairfax County (orange)

Late-reopening areas (blue, NoV+Richmond+Accomack) versus rest-of-state (orange)

Vienna, VA area ZIP codes.  Figures are today, and one week ago.

Post #757: Uptick. Not looking good.

Here are my three main graphs tracking COVID-19 cases locally and in Virginia, updated to today (7/15/2020).  Virginia topped 1000 new cases.  Last time that happened was more than a month ago.  But the “late reopening” areas continue to do OK.  If I have time, I’ll do a more complete drill down as a separate post.

Daily new cases, Blue = Virginia, Orange = Fairfax County

Daily new cases, Blue = NoVA+ (late re-opening areas), orange = rest-of-state

Finally, Vienna (22180) added eight cases over the last week.  Which is also an uptick from the prior weeks, but with such small numbers, you can’t make much out of that.

Post #G10: Squash Vine Borer: Thinking through neem and considering horticultural oil?

Edit 7/10/2022:  A lot of people find this post every year, when the squash vine borer is around.  This post is years old.  Let me summarize where things ended up:

  • Read Post #G27 for a summary of everything I found out about squash vine borer (SVB).
  • Spraying spinosad solution (0.008%) onto the stems of my summer squash every five days worked fine.  Kept the borer out, didn’t kill the bees.  And it’s a short-lived non-synthetic poison, so it should generate minimal collateral damage.  (E.g., won’t (or shouldn’t) build up in soil or fruit, run off and kill fish, or any of that. ) But that’s a lot of work, particularly given that the borer is around (in this climate) for eight weeks or so.
  • For 2022, I’m trying a completely different approach. I’m growing varieties of squash that don’t need to be pollinated (“parthenocarpic” varieties, Post G22-013).  I’m growing them inside an insect-proof hoop house to keep out the vine borer.  As of July 2022, that seems to be working OK.  But I started those late, and I still haven’t harvested any squash yet.

Edit 7/24/2024:  In the end, growing summer squash under netting, in my back-yard garden, was just too much hassle.  And I didn’t get much yield.  So this year I skipped the summer squash.  Instead I’m growing what are supposed to be close substitutes: Tromboncino (a winter squash) and guinea bean (an edible member of the gourd family).  These are solid-stemmed vines that, by reputation (and based on my experience this year), are not bothered by the SVB.

I can attest that immature (foot-long) trombincini fruits are an excellent substitute for zucchini.  But the yield seems poor, relative to zucchini or yellow summer squash.  It’s the end of July, the vines are huge, and so far I’ve picked two tromboncini, and the guinea bean has only started to set fruit.  Maybe they’ll pick up the pace in the heat of August?  But I’m not betting on it.  I’m guessing the low yield makes sense, else we’d all have been planting tromboncini instead of summer squash all along.

The original post follows.

I’ll try to avoid my usual TLDR style and get to the point.  A later section adds more detail.

I’m not going to try to get systemic protection using a neem “soil drench”.  Maybe I am going to use neem oil as a horticultural oil spray, hoping to smother the eggs.  But I am reluctant to do that, as nobody seems to be able to pin down why, exactly, neem oil should work against the SVB.  And even for a relatively harmless poison like raw neem oil, I’m reluctant to spray that in volume around my garden, when I really have no clue what it’s supposed to be doing for me in this case.

Post #756, Uptick in cases, continued

Here are my standard charts, updated to 7/13/2020.

In Virginia (blue, below), the seven-day moving average of new cases reached 800.  In Fairfax (orange), the seven-day moving average was steady at about 50 cases per day.  Both of those would be expected to rise a bit in the coming days as some low-count days pass out of the seven-day window, replaced by the most recent high-count days.

The problem continues to be outside of the late-reopening areas (Blue below, consisting of NoVA, Richmond City ,Accomack County).  Presumably, the problem continues to be in the Hampton Roads area, but I did not explicitly check that.

 

Post #755: COVID-19, younger people, and explosive growth. A theory, but no data.

Source:  New York Times 7/13/2020  Red and green markings were added for purposes of illustration.

1:  Young people.  The cases that are showing up, in these outbreaks, are far younger, on average, than COVID-19 cases to date.

2:  Explosive growth.  A second outstanding factor in those states was the extremely rapid ramp-up in the case load.  On the graphic above, the green line shows the worst rate of case growth experienced in Virginia.  If you look carefully, you can see that in the three key states, they went from well under that level well over that level in a single week.  And from there, to crisis levels of daily new cases in another week or two.  From “everything is fine” to “public health emergency” in the span of a few weeks.

3:  Relatively few deaths, as shown below.  In part, that’s because deaths lag infections by a couple of weeks, on average.  But these upticks have gone on long enough now that we can also say this is partly “real”, in the sense that the mortality rates do not (now) appear to be climbing as steeply as the new case counts did.

Source:  New York Times 7/13/2020  Red markings were added for purposes of illustration.

The fact that 1) and 3) are related is obvious:  The mortality rate ramps up steeply with age, and COVID-19 mortality case rate among young people is quite low.  I discussed this in Post #730, where I estimated the impact the shift in age mix on average mortality using data from the Virginia.

But I bet that 1) and 2) are also related.  Not due to “bad behavior” by young adults, per se.  (Though that certainly may contribute).  I think low age and explosive growth may go hand-in-hand merely as a matter of arithmetic.

This conclusion is an expansion of the addendum portion of Post #723.  The cases that get counted are just the tip of the iceberg of all infections.  Lately, FWIW, CDC estimated that there are, on average about 10 infections for every reported (diagnosed, tested) case.  (I saw FWIW, because that’s based on a sample of convenience in a handful of sites.)  But I’ll bet that with young adults, the size of the iceberg (all infections) is vastly larger than the tip of the iceberg (cases testing positive for COVID-19). 

And in that situation, you would, as a matter of arithmetic, expect the counted cases to grow much more rapidly.  In other words, for a given uptick in counted (diagnosed) cases, your actual underlying epidemic is much worse if those cases are all young people.  By interpreting the early upticks in these states using  historical norms for a much older COVID-19 population, the states missed out on just how widespread these outbreaks were.

If true, this matters to us here in Virginia, because the recent uptick in cases (see next post) in the Hampton Roads area has been reported to be due to cases concentrated among young adults.  If the theory above is right, then the current case counts underestimate total new infections by a much larger margin than has been historically true.  And so we risk seeing the type of unexpected explosion of case counts as has been noted elsewhere when this has morphed into a young person’s epidemic.

Details follow.

Post #754: Convalescent plasma, updated

Source:  US Centers for Disease Control.

I first wrote about convalescent plasma in Post #616, 4/9/2020.  The idea being, you take people who have recovered from COVID-19, filter the antibodies to COVID-19 out of the their blood, and give those antibodies to others, where they would help the recipients to recover from a COVID-19 infection.
