  • [ 52 ] The use of adamantanes, such as amantadine, has not been recommended since the 2005-2006 influenza season owing to resistance among influenza A viruses. (medscape.com)
  • Influenza A viruses are classified into subtypes on the basis of two surface antigens: hemagglutinin (H) and neuraminidase (N). Three subtypes of hemagglutinin (H1, H2 and H3) and two subtypes of neuraminidase (N1 and N2) are recognized among influenza A viruses that have caused widespread human disease. (canada.ca)
