1. Anyone claiming to know the death rate (mortality rate) is full of shit. (Reliable numbers would be needed to calculate)
2. Thinking this is as harmless as the flu is also stupid. (Nobody goes full hazmat, quarantine, or lockdown for the flu)
3. Source of origin is not known. (Whether natural or human influence)
What do we know?
It is serious.
If you live in China and try to inform the outside world, you disappear and or are arrested.
Actual numbers are not being reported and will not be. (Prevents fear and panic)
The number of tests that can be performed in a day are limited. (It takes time and resources to perform these tests)
The number of test kits available are limited. (It's not like we had millions of these things just laying around)
Crematoriums are at full capacity. (Doesn't mean that all cremations are from deaths from Coronavirus)
Cremations are a normal way of dealing with death in China. (Pre Coronavirus, and after)
Dead bodies on the streets, houses, hospitals, or anywhere are not having resources wasted on for testing for coronavirus, cause of death, or any reason, they are just being stacked in queue for disposal for sanitary reasons.
The unfortunate event of the Diamond Princess cruise ship being infected is the best controlled lab experiment we have to ascertain true numbers and studies that can be performed (If these are not also hidden from the public, but it would be harder since passenger and crew manifests exist). With the long incubation period involved just to begin showing symptoms, and then the amount of time required for the illness to run its toll, we are still looking at a month from now for figures that we can use to begin calculations to start rolling in.
Even if the mortality rate was 25% and took out 1,925,000,000 people it would still leave 5,775,000,000. That's assuming everybody contracted it. Big fucking whoop. It would probably take a decade to dispose of all of that and get back to normal, but it would not be the end all be all.
You would also have the fear factor and butthole factor that would also take lives, but that would be offset by the increase of birth rates. I could die, you could die, but we won't all die.
