Two years into the coronavirus disease 2019 (COVID-19) pandemic, we have now seen three main variant waves. We performed a retrospective cohort study of all pregnant patients with COVID-19 at our institution from March 22, 2020, to February 26, 2022, to evaluate disease severity and perinatal outcomes among the variants. Patients were categorized as pre-Delta (March 22, 2020-May 31, 2021), Delta (July 1, 2021-December 15, 2021), or Omicron (December 16, 2021- February 26, 2022) based on variant tracking from the Centers for Disease Control and Prevention and genotype sequencing at our institution. There were fewer cases of severe-critical disease (1.8% Omicron vs 13.3% pre-Delta and 24.1% Delta) and adverse perinatal outcomes during the Omicron wave compared with the pre-Delta and Delta waves.
在 2019 冠状病毒病（COVID-19）大流行的两年后，我们现在已经看到了三波主要的变异浪潮。我们对 2020 年 3 月 22 日至 2022 年 2 月 26 日期间我院所有 COVID-19 孕妇患者进行了回顾性队列研究，以评估变异株之间的疾病严重程度和围产期结局。根据美国疾病控制与预防中心的变异追踪和我院的基因分型测序，患者被分为德尔塔前（2020 年 3 月 22 日至 2021 年 5 月 31 日）、德尔塔（2021 年 7 月 1 日至 2021 年 12 月 15 日）或奥密克戎（2021 年 12 月 16 日至 2022 年 2 月 26 日）。与德尔塔波相比，奥密克戎波期间严重/危重症病例（1.8%奥密克戎 vs 13.3%德尔塔前和 24.1%德尔塔）和不良围产结局较少。
