I addressed what
@AltisticRight said. In fact, I dragged up the rest of the graphs that supported the argument that the data was fabricated to fit a curve.
I was going to let his last post slide unchallenged, but since you sassed me up, now I have to go back.
I like how you pretend that these data sets are in any way equivalent.
South Korea and Singapore have comprehensive screening programs in place, while the authorities in China have basically stopped counting cases.
What this means is that South Korea and Singapore will be counting a much, much larger number of asymptomatic and mild cases than anywhere else.
South Korean has had success managing the coronavirus undefinedoutbreak. New cases diagnosed Monday dropped to 47undefined, the lowest level in weeks.

Not only does this mean that they'll be better off at preventing the spread of the virus, it also means that their ratio of total cases to total deaths will look better than in other places. I find it amusing that the 1 in 55 death rate in Korea matches the presumed IFR of the disease almost exactly, about 1.8%, squarely in the middle of the 1 to 3% figure I've been hearing. This means that South Korea is detecting a very, very large number of the infections.
The actual number of cases may actually be in the tens of millions, according to the report.

So, here's a little experiment for you. Try adjusting your presumed RCFR ratios based on the actual detection rate, and
then see where China lands.
Don't feel too bad. The US is doing the worst of all. The CDC demonstrated extreme incompetence bordering on criminal negligence.
States are testing fewer than 100 people a day and the CDC tested even fewer in an entire week.

Yes, exactly. It has largely the same effects as SARS-CoV. That's exactly what I've been saying this entire time. What makes this particularly infuriating is how the medical literature on COVID-19 almost refuses to acknowledge the multi-faceted features of SARS-CoV's pathology, including the vascular and neurological complications.
Reports are scant. Don't pretend that one single blurb in one single paper is enough to get the attention of every doctor treating every patient.
I have been tracking that information, yes. I am aware that 70 to 80% of the patients being intubated have died, yes.
Hah. Finally. Someone with actual knowledge.
There are numerous mechanisms at work here that have nothing to do with the interior of each alveolus and everything to do with the physiology of the vascular system, and the way the virus affects it.
First of all, this virus inhibits the entry receptor, ACE2, and causes Angiotensin II to back up. Has anyone considered that pulmonary hypertension in the capillaries of the alveoli may be a problem, because of the excess Ang II?
Dr. Nick Mark, on Twitter, describes a capillary shunt mechanism by which hypoxic pulmonary vasoconstriction may close off blood supply to the capillaries and harm oxygen exchange with the alveoli:
Thread by @nickmmark: Lots of talk about funny hemoglobin and ‘happy hypoxic’ people with #COVID19. I think we can explain everything using p pulmonary physiology. Let’s dive into hypoxic pulmonary vasoconstriction (HPV) and hypoxic ventilatory drive (HV…

This is all fine and good, but did he take into account that the virus imbalances the RAAS and causes an over-abundance of a vasoconstrictive hormone that could do the same thing as hypoxic pulmonary vasoconstriction?

It could be hypoxia closing off those capillaries. It could also be that the tissues are saturated in Ang II commanding them to constrict. How would you be able to tell the difference without biopsying the tissue?
Next, you have Dr. Farid Jalali's hypothesis of micro-thromboembolism blocking off capillaries because of diffuse clotting:
Do we know if the blockage of the alveolar capillaries is due to vasoconstriction, or is it due to a proliferation of many tiny blood clots?
Last, but not least, there's this:
The novel coronavirus pneumonia (COVID-19) is an infectious acute respiratory infection caused by the novel coronavirus. The virus is a positive-strand RNA virus with high homology to bat coronavirus. In this study, conserved domain analysis, homology modeling, and molecular docking were used to...

COVID-19 can apparently interrupt heme metabolism, resulting in a whole lot of free heme floating around and perhaps even progressing to hemolytic anemia. This seems to be supported by the high ferritin findings and the clotting. This is what excess free heme can do:
However, the diffuse clotting could also potentially be caused by viral sepsis, regardless. Therefore, the heme metabolism interruption hypothesis does not rule out coagulation by other causes.
In summary, COVID-19 is a vascular disease with lung signs
secondary to the vascular manifestations. It attacks the blood and blood vessels first, and
then your lungs get fucked.
That's why people are sitting around jawing looking fine, and then suddenly, they're hypoxic and blue in the face.
A few competing hypotheses, here. Which is it, genius?
- Does the virus close off alveolar capillaries with hypoxic pulmonary vasoconstriction, or does Angiotensin II cause them to constrict by activating AT1R?
- Are the capillaries being blocked by huge numbers of tiny blood clots due to vasculitis and/or viremia?
- Is the virus attacking heme metabolism and causing large amounts of free heme to float about, causing lowered hemoglobin, hypoxemia, elevated ferritin, and clotting?
