Snotty noses, aching heads and school or work absenteeism. It’s the gift that keeps on giving, but that nobody wants. This year, the season of viral giving started earlier than usual, and flu is ...

No patients with resistant viruses reported prior exposure to oseltamivir. In the 2008--2009 season (through February 19, 2009), 98% of 268 isolates were resistant to oseltamivir.

Still, oseltamivir is a safe drug, she said, and given the uncertainties over how severe a case of H5N1 could become, use of the antiviral makes sense. Public health authorities agree.
