CDC, 5/21/20 https://www.cdc.gov/coronavirus/2019-ncov/hcp/planning-scenarios-h.pdf, concedes infection fatality ratio (IFR of) “Covid19/Wuhan flu” is = 0.27%*, almost= to 1957-58 pandemic H2N2 flu in U.S., i.e., 0.26%** h/t @ElonBachman BUT NO "LOCKDOWNS" in 1957-8! (1/3)…

…(2/3) Because U.S. did not “lockdown” in 1957-8, as noted by great epidemiologist D.A. Henderson, the H2N2 pandemic “did not appear to have a significant impact on the U.S. economy” http://www.upmc-biosecurity.org/website/resources/publications/2009/2009-08-05-public_health_medical_responses_1957.html

3/3 Henderson also observed, re: 1957-8: “Measures were generally not taken to close schools or recommend wearing masks; Quarantine was obviously useless because of the large number of travelers & frequency of mild or inapparent cases” http://www.upmc-biosecurity.org/website/resources/publications/2009/2009-08-05-public_health_medical_responses_1957.html
