I didn't mean to imply that the number was necessarily wrong. I looked around for a reference but couldn't really find anything. The thing is, real time RT-PCR works by detecting specific viral sequences. If those are chosen prope

Yeah, I misremembered the growth rate in Italy. But check out the reference that I provided, most countries are in the high 20s / low 30s, many of them for multiple weeks. If there really was a 10% "true" growth, and higher g

Could you please cite a source for the false positive rate? Real time RT-PCR should be nowhere near that. Maybe if your sample handling is messed up, but that should be easy to optimize...

Could you expand on your observation regarding the true growth rate? I don't think that's accurate. Italy's outbreak is entering its fourth week, they have a very constant daily factor of ~1.33. Most countries are on the same

Definitely insane, here's why: In order to get to herd immunity, you need something around 60% of the population to get infected and thus immunized [0] (there's a big assumption here already, that immunity lasts forever, might wel

The preprint you have quoted shows that the novel virus genome is very similar to a different Coronavirus (RaTG13) in some parts, and less similar in others. We have only a small sample of all the Coronavirus genomes that are out there in a

What you are saying is theoretically possible, but the sibling comment that's getting downvoted right now invoking Occam is, I think, spot on. Why hypothesize a detour through a biomedical lab if we know that people can get these disea

The title is shortened in a somewhat misleading way, making it sound at if this might be about a clinical study. The full title is: "Coronavirus Susceptibility to the Antiviral Remdesivir (GS-5734) Is Mediated by the Viral Polymerase a

The view you are suggesting works, in the sense that it is logically consistent. However, I very much doubt that this is the calculation that went through very many people's heads, say, 3 weeks ago. I think proof of this is that in all

You make a great point. Now how do we fix it? To your 15% chance of disaster example from your other comment: I think what you need is a population where a large fraction of people understand where those 15% come from. Edit: I also want to

It's also a great demonstration that it's really hard to get people to believe that something they can't see is real. Coronavirus cases have been growing stably and predictably for weeks. Epidemiologists (and not only they) s

I'm well aware of the difference between IFR and CFR. CFR is nowhere in the range you quoted. Being consistent with incorrect studies is nothing to brag about. Re South Korea: You are presenting a hypothesis as fact. For lots of reason

The crucial thing is that the daily growth rate in South Korea averaged over the last 7 days is 1.05 and sinking, a far cry from the stable ~1.33 average in European countries with significant outbreaks. It's outrageous to me that you

For weeks I've been hoping to find a way to quickly compare log-plots of numbers infected (optionally normalized to population size) for different countries. IMO the best way to look at world-wide spread, but doesn't seem to be av

That's not true, case numbers in France and Germany are highly correlated. What you are saying would imply a substantial difference in growth rate between the two countries, which is easily disproved by looking at the data.

But you can compare this ratio between countries that have similar numbers of cases to get a hint at relative detection efficacy, assuming constant CFR.

That's not all there is to it, since the number of people infected grew at a similar pace in the early phase of an outbreak in different countries. For example, the number of people infected in France and Germany is rising in near perf

Something needs to explain the difference though between 939:0 in Germany and, e.g., 949:11 in France. Maybe the diagnoses in Germany are closer in time to infections? That would still point to a higher reporting rate in Germany vs. other

This model is nice in principle, but its results depend crucially on what is ultimately an educated guess of the reporting rate of symptomatic cases. This parameter can be found experimentally by testing for antibodies against the virus in

You're right it can be impractical. For me I mostly solved it by 1) giving back the 1, 2 and 5 cent coins I receive as change and 2) withdrawing cash with my grocery purchases, which is possible in many stores.
