CDC比較每1000人感染數，住院數和死亡數。結論Omicron比Delta住院下降78至27，死亡下降13到9。那豈不是說Omicron住院者死亡率遠高於Delta住院者（9/27 vs 13/78)，高出一倍。這明顯不合常理，甚為荒謬。我們都知道Omicron住院病人通常較輕，很少有上呼吸機的。能推導出如此結論，明顯研究方法有問題。很難相信CDC這樣的文章也能發表。
原文：
The ratio of peak ED visits to cases (event-to-case ratios) (87 per 1,000 cases), hospital admissions (27 per 1,000 cases), and deaths (nine per 1,000 cases [lagged by 3 weeks]) during the Omicron period were lower than those observed during the winter 2020–21 (92, 68, and 16 respectively) and Delta (167, 78, and 13, respectively) periods.
