CDC比较每1000人感染数，住院数和死亡数。结论Omicron比Delta住院下降78至27，死亡下降13到9。那岂不是说Omicron住院者死亡率远高于Delta住院者（9/27 vs 13/78)，高出一倍。这明显不合常理，甚为荒谬。我们都知道Omicron住院病人通常较轻，很少有上呼吸机的。能推导出如此结论，明显研究方法有问题。很难相信CDC这样的文章也能发表。

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.
