Influenza Clinical Trial
Official title:
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.
