Antiviral resistance and influenza

A recent survey by the CDC has revealed that about a quarter of primary care physicians were still prescribing older antiviral drugs for influenza during the last flu season. Why is this a problem? The CDC has warned against the use of these older antivirals because of viral resistance. In January 2006, the CDC recommended that physicians stop prescribing amantadine and rimantadine because of high rates of resistance among strains of influenza A. Despite the warning, an estimated 26.4% of physicians continued to prescribe these drugs in the 2006-07 flu season. Looks like we need some new antivirals...
