Adult patients hospitalized with influenza have higher viral loads and more severe illnesses. Thus more aggressive treatment approaches (e.g. higher dose oseltamivir) have been suggested to treat patients suffering from severe influenza infection.
The investigators plan to investigate the impact of higher-dose oseltamivir (150 mg b.d.) treatment on viral clearance and clinical recovery in adult patients hospitalized for severe influenza. Such information may lead to optimization of the management strategy used for these patients.
