As authorities braced for the arrival of the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), infrastructure investments and government directives prompted action in central Viet Nam to establish capacity for genomic surveillance sequencing. From 17 November 2021 to 7 January 2022, the Pasteur Institute in Nha Trang sequenced 162 specimens from 98 150 confirmed SARS-CoV-2 cases in the region collected from 8 November to 31 December 2021. Of these, all 127 domestic cases were identified as the B.1.617.2 (Delta) variant, whereas 92% (32/35) of imported cases were identified as the B.1.1.529 (Omicron) variant, all among international flight passengers. Patients were successfully isolated, enabling health-care workers to prepare for additional cases. Most (78%) of the 32 Omicron cases were fully vaccinated, suggesting continued importance of public health and social measures to control the spread of new variants.
随着当局为严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）的奥密克戎变体的到来做准备，基础设施投资和政府指令促使越南中部采取行动，建立基因组监测测序能力。从 2021 年 11 月 17 日至 2022 年 1 月 7 日，芽庄巴斯德研究所对 2021 年 11 月 8 日至 12 月 31 日期间从该地区 98150 例确诊的 SARS-CoV-2 病例中采集的 162 个样本进行了测序。其中，所有 127 例国内病例均被鉴定为 B.1.617.2（德尔塔）变体，而 92%（32/35）的输入性病例被鉴定为 B.1.1.529（奥密克戎）变体，均为国际航班旅客。患者被成功隔离，使医护人员能够为更多病例做好准备。32 例奥密克戎病例中，大多数（78%）完全接种了疫苗，这表明继续采取公共卫生和社会措施控制新变体的传播仍然很重要。
