Genetic characterisation of the influenza viruses circulating in Bulgaria during the 2019–2020 winter season

22 Jun 2021

Abstract excerpt

Influenza viruses have a high potential for genetic changes. The objectives of this study were to analyse influenza virus circulation in Bulgaria during the 2019/2020 season, to perform a phylogenetic and molecular analyses of the haemagglutinin (HA) and neuraminidase (NA) sequences of representative influenza strains, and to identify amino acid substitutions compared to the current vaccine strains. Seasonal...
