Abstract
Based on partial sequencing data of the S gene from 2 066 clinical samples, the spectrum of SARS-CoV-2 variants was determined and the characteristics of their spread in the Republic of Belarus in 2020–2021 were established. At the beginning of 2020, predominantly early «Wuhan» variants were identified: A.1 in Minsk and B.1 in the Vitebsk Region. In the 2nd–3rd quarters, all analyzed sequences belonged to variant B.1, which remained the leader in the 4th quarter (90,6%). Rare B.1 sublineages collectively accounted for 9,4%, among which variant B.1.1.374 predominated. Regional differences during this period were not significant (p>0,05). The Alpha variant displaced the early variants (including B.1.1.374) in the first quarter of 2021, becoming dominant. The Delta variant, represented predominantly by AY.4, began to active spread from May 2021 and by summer completely replaced Alpha. Regional differences in 2020–2021 were not significant (p>0,05).
