This short April 27th post by Karl Denninger is a good summary of the facts as known so far. My summary (with comments):

  • What was demonstrated by the Diamond Princess cases (that despite being very close proximity not everyone became infected and at least 50% of infections show no symptoms).
  • What was demonstrated from early March by the Kirkland, Washington, nursing home debacle (Kirkland now facing at least one “wrongful death” lawsuit) was that nursing homes and hospitals were a major vector and therefore inaction by the owners of those institutions and by the governors of those States is tantamount to negligent homicide. (If elected President, Denninger promises to hold those folk criminally and civilly liable, and deny Medicaid funds to institutions that continue to refuse to obey the law. He does not seriously expect to be drafted, I might add.)
  • Testing has proved that mitigation policies do not, cannot and have not stopped transmission.
  • Lockdowns are a waste of time and probably indirectly harm and kill people, as shown by serologic surveys.
  • The data out of Wuhan showed that vents were mostly ineffective, and therefore trying to “flatten the curve” which means making vents available, “driving people into hospitals and encouraging invasive procedures” was and is counter-productive and even dangerous. Adding financial incentives to do that is manslaughter and should be dealt with accordingly. I don’t agree with this entirely: while it is now clear that vents kill more people than they save and why, hospitals may still be the best places for seriously ill people to get the prophylactic treatment they need.
  • Data now proves (what was fairly obvious from early on, especially when considering historical examples such as the 1918-19 “Spanish” flu (which started in the US and was spread to Europe by US soldiers, and the 1950s Canadian polio epidemic ) that the sanatorium model is the most rational way to deal with the seriously ill or compromised patients. (“Her day would end 12 hours later by carefully removing the awkward gown, gloves and mask she wore, ensuring as she did that none of her clothes became contaminated. She would return to the former army barracks where she and other nursing students lived in isolation, their food delivered from the hospital cafeteria.”)
  • Since a huge percentage of those infected are not harmed at all or only have minimal symptoms you want to encourage that event since it is the only means to build immunity in the population.  (But there is some doubt as to whether immunity is acquired and how long it lasts for: see especially 1.10 of this report by Belgian specialist Marc Wathelet.)
