The second wave of Covid

@Horace said in The second wave of Covid:
You said the CDC model was obviously wrong
Yes.
I predicted that the CDC model would be closer to the reality of our future national statistics than the NYC numbers.
Yes you did, and you invited me to take the other side of the bet. I specifically declined to do so, rather I gave you my own prediction. I forget what lower bound I used, the upper bound was .75%.

earlier bit quoting Jon that Jon accidentally deleted
Ok then, you are riding that line between thinking a model is obviously wrong because it doesn't conform with a certain subset of the data, while allowing that the model is closer to the truth than that subset.

No, I don't disagree with the specific prediction about shelter-in-place.
I think they were superfluous because localities had closed all the places you'd want to go, and had enumerated exceptions for all the other reasons you'd leave the house.
So they were basically symbolic, and governors will be keen to avoid that particular symbolism, whereas three months ago they were keen to embrace it.

Horace I apologize, I hit 'quote' instead of 'edit' on your post.
My apologies.

The article looks at data compiled by The Washington Post and draws these conclusions:
Nationally, across the US it is possible to detect a downwards trend in the number of new COVID-19 cases and deaths. The epidemic appears to have peaked in early April and tailed off since then — just as it has in Europe. But that isn’t the whole story. Drill down state by state and there is a very mixed picture. Study the graphs which the Washington Post has helpfully put online and you can put states into three distinct groups. Firstly, there are those states where the epidemic curve is clearly in decline and has been for some weeks. There are 15 of these. Most obvious is New York but others include Massachusetts, New Jersey, Pennsylvania, Illinois. Away from the North East, Colorado, Wyoming, Louisiana, Nebraska and Hawaii also fall into this category.
Then there are the states where the first peak has not yet significantly declined. There are 30 states which fall into this category, including California, Texas, Georgia, Ohio, Iowa, Kentucky, New Hampshire, Maine, Michigan, Maryland, Minnesota. Mississippi, West Virginia and Wisconsin. Most of these states have rolled back restrictions on movement and forced closures of businesses but did so before there had been any appreciable fall in cases. Currently there is no obvious trend either way.
But then there are six states which, worryingly, are showing a detectable second spike. In Florida, for example, new infections fell from over 1,000 a day in early April to around 600 a day a month later. The state began to reopen on May 4. Since then, however, new infections have climbed back to their previous peak, reaching 1,419 on June 4 — the highest yet. It is a similar story in Arkansas, where cases had fallen from a peak of 402 on April 22 to 27 on May 15 before rising again to a new high of 450 on June 6. In Vermont the epidemic seemed all but over on May 12 when zero cases were recorded. For three weeks after that cases remained low. But over the past week there has been a rebound, with 72 cases reported on June 4. The other states with a discernible second spike are Alaska, Montana and Washington.
Is this a dire warning of what is to come? First it needs to be noted that none of these states had especially high peaks to start with. It would be a very different matter if New York started to show a second spike. Secondly, the number of reported cases does not necessarily reflect reality — it depends very much on the number of people being tested. It is a peculiarity of COVID-19 that there are huge numbers of asymptomatic cases — possibly as many as 80 percent fall into this category — and that most of these are going unrecorded. Thirdly, there has been no sign of a second spike in badly-affected European countries — even though most have reopened much of their economies and have lifted restrictions on personal movement. Across the world, the only nations showing any kind of second spike are those which, like South Korea and Singapore, succeeded in suppressing the number of cases very early on. And even they haven’t seen much in the way of spikes.Nevertheless, all eyes over the next few weeks are going to be on those US states which seemed to have suppressed the virus only for it to rebound.

It's simple.
All the protesting: If there is a big spike within the next couple of weeks, then I predict another big spike in the fall.
If there is only a bump as a result of the protesters hanging out in close proximity, then I predict no big increase in the fall.
