Surge of severe acute respiratory syndrome coronavirus 2 infections linked to single introduction of a virus strain in Myanmar, 2020
Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is a major health concern globally. Genomic epidemiology is an important tool to assess the pandemic of coronavirus disease 2019 (COVID-19). Several mutations have been reported by genome analysis of the SARS-CoV-2. In t...

Genomic epidemiology is an important tool to assess the pandemic of coronavirus disease 2019 (COVID-19). Several mutations have been reported by genome analysis of the SARS-CoV-2. In the present study, we investigated the mutational and phylogenetic analysis of 30 whole-genome sequences for the virus's genomic characteristics in the specimens collected in the early phase of the pandemic (March–June, 2020) and the sudden surge of local transmission (August–September, 2020). The four samples in the early phase of infection were B.6 lineage and located within a clade of the samples collected at the same time in Singapore and Malaysia, while five returnees by rescue flights showed the lineage B. 1.36.1 (three from India), B.1.1 (one from India) and B.1.80 (one from China). However, there was no evidence of local spread from these returnees. Further, all 19 whole-genome sequences collected in the sudden surge of local transmission showed lineage B.1.36. The surge of the second wave on SARS-CoV-2 infection was linked to the single-introduction of a variant (B.1.36) that may result from the strict restriction of international travel and containment efforts. These genomic data provides the useful information to disease control and prevention strategy.Myat Htut NyuntHnin Ohnmar SoeKay Thi AyeWah Wah AungYi Yi KyawAung Kyaw KyawTheingi Win MyatAung Zaw LattMin Min WinAye Aye WinYin Min HtunKhaing Mar ZawPhyu Win EiKyaw Thu HeinLai Lai SanNan Aye Thida OoHtin LinNan Cho Nwe MonKhin Than YeeKhin Lapyae HtunLynn Pa Pa AyeYamin Ko KoThitsar Htet Htet HtooKham Mo AungHnin AziliSoe Soe HanNi Ni ZawSu Mon WinWai Myat ThweThin Thin AyeMyat Su HlaingWai Yan MinnPyae Phyo ThuHlaing Myat ThuZaw Than HtunNature PortfolioarticleMedicineRScienceQENScientific Reports, Vol 11, Iss 1, Pp 1-6 (2021) |
