Shedding of influenza in hospitalized patients

In this single center study, researchers examined the prevalence of prolonged shedding of influenza virus in hospitalized patients (detected by culture and PCR). Of 147 patients, viral RNA was detectable 1 week after symptom onset in 26% of oseltamivir-treated patients, and 57% of untreated patients. Prolonged clearance was associated with co-morbidities and systemic steroids (for asthma or COPD). In these high risk patients, prolonged viral shedding should be expected (abstract).
