Thirty partial coding DNA sequences (CDSs) of the spike gene of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were obtained from nasopharyngeal swab samples collected in March to July 2021 in Dhaka, Bangladesh, during the second wave of the coronavirus disease 2019 (COVID-19) pandemic, using Sanger sequencing technology. Sequence analysis showed the presence of multiple WHO-designated variants of concern (VOCs), including Alpha, Beta, Gamma, and Delta, with predominant circulation of Delta variants during that period.
2021年3月至7月，在孟加拉国达卡，于2019冠状病毒病（COVID-19）大流行的第二波期间，通过桑格测序技术从鼻咽拭子样本中获得了严重急性呼吸综合征冠状病毒2（SARS-CoV-2）刺突基因的30个部分编码DNA序列（CDS）。序列分析显示存在多种世界卫生组织指定的关注变异株（VOC），包括阿尔法、贝塔、伽马和德尔塔，在此期间德尔塔变异株占主导传播。
