I won’t respond to your points specifically, but I will point out:
The Diamond Princess cruise ship (quarantined in Japan) had 3,000 mostly seniors as passengers. Less than 800 got the China Virus, and 7 died, all of whom had significant, underlying respiratory issues. That’s less than a 1% mortality rate of SENIOR CITIZENS who actually got infected. Keep in mind that some or all of the 7 dead would have survived had they had access to American hospitals. The bulk of the seniors who were infected had zero or minimal symptoms. A cruise ship is a great petri dish to study how deadly a virus is. It’s confined, and you have very little chance of “social distancing.” A 1% mortality rate on a senior-laded cruise ship (docked in Japan) equates to a VERY LOW mortality rate for Americans who have access to quick, responsive medical care.
Some speculation that some of the passengers had taken anti malaria drugs before the cruise if true that could skew the stats
Pretty much sounds like a well controlled (by pure coincidence) experiment. And as a frequent cruiser, I can verify there a LOT of folks not in robust health as passengers, especially during calendar periods when school is in session, the passenger roster skews real old.
I already corrected some of your misperceptions.
They weren’t all sitting in the Grand Ballroom playing bingo. They were distributed in chunks with separate air and private bathrooms, had masks and other prophylactic items, practiced social distancing including confinement, and had all of the resources of an entire country focused on them. It wasn’t the petri dish some are describing it as.
Also, 8 people on the ship have died and 1 that was returned to the US has also died. That we know of. And even after all this time, 127 cases are still unresolved. The death rate among cases sent to our superior HCS is twice that for the rest of the infected. Overall, it is comparable with the SK stats. Except more time has passed and we still have a crowd of infected - 18% have yet to recover or die.
