    H5N2 is not a new virus, it’s well known to virologists.

    Influenza A virus is classified into subtypes based on the viral proteins haemagglutinin (H) and neuraminidase (N). As of 2019, 18 H subtypes and 11 N subtypes have been identified. Most potential combinations have been reported in birds, but H17-18 and N10-11 have only been found in bats. Only H subtypes H1-3 and N subtypes N1-2 are known to have circulated in humans
