Depends what you consider knocking out. I know individuals under 50 hospitalized and one was in ICU on a vent for more than a week. Yeah young people can usually beat it before dying, but it’s not like it’s a walk in the park.
Look up 2007 Findings about Sars Virus in The American Society for MicroBiology. Its a blue print on what should have been done.Its a publication that used over 4000 papers to create a history of Sars. It also mentions Corona virus and where next outbreak may come. This paper was right. It also documents use of Chloroquine. It showed ineffectiveness of use. It shows everything tried against virus. Also documents deaths attributed from heart attacks due to virus..These are not being counted now. This paper shows Patient 0 and what was tried in order to help those infected...It also warned of where next outbreak would probably happen..They also documented the Corona virus in bats..The Sars Virus caused a huge depression..They pretty much said a worse one may come...And here we are..
