The data from the last few days is going to be clunky because of the usual weekend lag in reporting and Easter but even given that it seems fair to say that we have successfully made the derivative of the new deaths curve constant. Maybe even close to zero. The main questions now for me: 1) how long is the plateau/descent. Long tail gets us to 100k verified dead. 2) what is the temperature effect on R? It looks to be real. Is it big enough to explain the relatively fewer cases in the American South? Can we hope for a summer respite?
This will be an informative week. We should know how good the IHME model is by weeks end.

(12,712 posts)I am wondering about the rural factor, though. It seems that the impact in outlying, rural areas is just starting to get going and that we might anticipate an increase in cases as it spreads out.
There are also several factors involved in the mortality rate for those areas that might indicate an increased death toll, per capita.

(4,602 posts)Its on the lower band of high reporting states. As many cases as Louisiana but half the fatality rate.
Louisiana is a special case almost all due to marriage gras.

(28,460 posts)Scott is purposefully keeping information close to the vest and limiting testing to give the impression they're doing better than they are.

(42,296 posts)When they report on the test backlog, they only include public lab tests. That's only 10% of the tests that are backlogged - the rest are from private labs.
This is far from over. Florida is a cesspool of infection.

Looks like from what Cuomo was saying is there needs to be population density or gatherings that kick off CV19 flares

(4,602 posts)I think seasonal variation MAY be ever so slightly lowering the R0 in many cases.
Of course thats the hopeful interpretation.

(42,684 posts)And they have way more cases than, for example, Wisconsin -- which I'm pretty sure isn't as warm as either of those states.

(4,602 posts)Im sure you understand that correlation is probabilistic.
Ill post the regional breakdowns for you when I get a moment.

I swear the testing has been criminal

(4,602 posts)As this is percentage of tests returning a positive result. Im not clear on how lag in tests returns affects that number as its normalized by number of tests. Are positive tests being returned quicker than negative? There may be other reasons they Im not seeing of course.

(90,335 posts)... going to be a dip in positives test for that day.
They can either stop processing test or stop taking them
In the link in the tweet it explains a lag in the "slow down" isn't in deaths its in positive test and its on the chart from covid tracking
4,5,6 and it was also at the end of March ... hmmmm, doesn't look like NOLA is tracking test taken vs positive numbers either the two have to stay calculated together

(19,023 posts)Theres too many states going up and down and theres 50 different approaches. Give it more than 3 data point in this case to spot trends.

(26,727 posts)Generally speaking, positive tests can be expected to peak before hospitalizations... which in turn can be expected to peak before ICU demand... which in turn can be expected to peak before deaths.
Deaths may be only on a three-day decline (though, to be fair, it really close to a week if you average out the curve) - but the peak for new cases in the US appears to have been back on the 4th.
The OP is correct. By the weekend, we could have enough data to validate their (adjusted) projections.
Which, of course, says nothing about what happens when various flavors of unlocking occur. My understanding is IHME is close to releasing models predicting that.
