@OmicronData @BallouxFrancois @Fiona_M_Russell It was low in 2020-2021 in large part because of low to no covid (unless you do blanket mass testing, who are you going to test?). Positivity rates were in line with other countries and excess mortality was low or negative.
Omicron wave is undertested.
@OmicronData @BallouxFrancois @Fiona_M_Russell 2020-2021 年的价格很低，很大程度上是因为新冠病毒低到没有（除非你进行全面质量测试，你要测试谁？）。阳性率与其他国家一致，超额死亡率低或为负。
Omicron 波未得到充分测试。
