Evaluation of Viral Shedding Patterns and Clinical Outcomes of Influenza Patients

August 21, 2014 updated by: Crucell Holland BV

Prospective Study to Evaluate Viral Shedding Patterns and Clinical Outcomes of Hospitalized Adult Influenza Patients

The objective of the study is virological assessment (e.g., proportion of prolonged viral shedding, median days to viral clearance, and viral load) in laboratory-confirmed adult influenza patients admitted to the general ward and/or to the ICU and to assess the correlation with the clinical manifestations and prognosis.
