新冠压平曲线战略是根据流感经验而制定的，对新冠疫情效果不佳，但对流感效果非常显著，以至于2020-2021流感季节几乎没有流感。对于新冠疫情，专家们犯了经验主义和教条主义错误，方不对症。
以下抄自CDC的流感总结。从流感这个侧面，也可以看出在Omicron这轮疫情，美国不少人自发地抛弃了压平曲线而选择了反向隔离。
The overall burden of influenza (flu) for the 2019-2020 was an estimated 35 million flu-related illnesses, 16 million flu-related medical visits, 380,000 flu-related hospitalizations, and 20,000 flu-related deaths
During September 28, 2020–May 22, 2021 in the United States, 1,675 (0.2%) of 818,939 respiratory specimens tested by U.S. clinical laboratories were positive for an influenza virus.
CDC estimates that, so far this season, there have been at least 6.4 million flu illnesses, 65,000 hospitalizations, and 4,000 deaths from flu.
