Hm .. check this .. SARS had almost 10% mortality. Scary.
This looks way better so far. But !
Imagine you are confirmed case. How long till you die after that ? That delay is crucial.
We know SARS had almost 10% now, when it's already over.
But nCov-2019 is not over. It's developing. And it's developing very fast, exponentially, and btw. way faster then SARS. SARS had 8000 cases total.
If we want to compute mortality, we can't just take dead-today/confirmed-today. We have to take number of confirmed people from when the person became confirmed. Let's say it take one week, on average, to die after you are confirmed case. So let's take number of dead today, ie 171, and number of confirmed cases one week back. ie 639.
That's 26%. That's apocalypse.
There are of course many other factors, which throw it out of the window. Some good. Like there is actually lot of undetected cases, as these are confirmed, PCR tested cases. There is not enough capacity to test everyone. And with that comes bad factor. It's said that only live people are tested, so there might be more dead than reported.
Guess we will only learn more when cases outside Chine become better know, and sadly, when's there more of them.
