On May 3, 2020, Dr. Debora Birx, a member of the US Coronavirus Taskforce, admitted they “underestimated very early on the number of asymptomatic cases…I think we’re really beginning to understand there are people that get infected that those symptoms are so low-grade that they don’t even know that they’re infected.” (Could asymptomatic be because in Oct-Nov-Dec 2019, the previous flu season they already were exposed to the coronavirus pathogen and had developed antibodies? [2, 3] )
She also acknowledged that “many of those dying from coronavirus have other diseases, such as heart disease or problems with their immune systems,” something that was known for months. “Dr. Birx also reiterated her view that the most important way to get rid of the virus is with a vaccine.”
By this stage there had been atleast five studies that found the coronavirus has a fatality rate of less than 1%, similar to a bad flu season and has never warranted lockdown of a healthy population.
By May 22, 2022 the CDC‘s “current best estimate” is that 35% of infections are asymptomatic and the Symptomatic Case Fatality Ratio, is 0.004%. [1]
