ABSTRACT
United Kingdom reported the emergence of a new and highly transmissible SARS-CoV-2 variant B.1.1.7. that rapidly spread to other contries. The impact of this new mutation that occurs in the S protein, on infectivity, virulence and current vaccine effectiveness is still under evaluation. We have identified the first cases of the B.1.1.7 variant in samples collected from Romanian patients, of which one was traced to the UK region where the new variant was originally sequenced. Mutations in the Nsp3 protein, N844S and D455N and L15F in Orf3a were also detected, indicating common ancestry with UK strains as well as remote connections with strains from Nagasaki, Japan. These results indicate, for the first time, the presence and characteristics of the new variant B.1.1.7 in Romania and underscore the need for increased genomic sequencing in confirmed COVID-19 patients.
