Abstract
The adamantanes (amantadine and rimantadine) were the initial antivirals licensed for use against influenza A viruses and have been used in some countries to control seasonal influenza and have also been stockpiled for potential pandemic use. While high rates of resistance have been observed in recent years with A(H3) viruses, the rates of resistance with A(H1) viruses has varied widely. In this study we analysed 281 human influenza A viruses isolated in 2007 that were referred to the WHO Collaborating Centre for Reference and Research in Melbourne, mainly from Australia and the surrounding regions, for evidence of resistance to adamantanes and a subset of these was examined for resistance t..
