Influenza caused by an oseltamivir-resistant influenza A(H1N1) virus was widespread across Europe during the 2007–08 winter.1 About 25% of A(H1N1) viruses tested in the European Influenza Surveillance Scheme (EISS) were resistant with an H274Y mutation in the neuraminidase glycoprotein.1 Early indications during the 2008–09 season are that a large proportion of circulating A(H1N1) viruses have retained oseltamivir resistance, and that the resistant virus will likely become dominant in the United States but not in Europe.2,3 Further analyses have indicated that these oseltamivir-resistant A(H1N1) viruses retain sensitivity to zanamivir and the M2 ion channel inhibitors (M2Is).1

Two classes of drugs are used in the treatment and prevention of influenza: the M2Is (amantadine and rimantadine) targeting influenza A viruses, and the neuraminidase inhibitors (NIs; oseltamivir and zanamivir),
