摘要：The Influenza Complications Alert Network (FluCAN) is a sentinel hospital-based surveillance programthat operates at sites in all states and territories in Australia. This report summarises the epidemiologyof hospitalisations with laboratory-confirmed influenza during the 2016 influenza season.In this observational study, cases were defined as patients admitted to one of the sentinel hospitalswith an acute respiratory illness with influenza confirmed by nucleic acid detection. Data are also collectedon a frequency matched sample of influenza negative patients admitted with acute respiratoryinfection as a control group.During the period 1 April to 30 October 2016 (the 2016 influenza season), there were 1,952 patientsadmitted with confirmed influenza to one of 17 FluCAN sentinel hospitals. Of these, 46% were elderly(≥65 years), 18% were children (<16 years), 5% were Aboriginal and Torres Strait Islander Peoples, 3%were pregnant and 76% had chronic co-morbidities. A small proportion were due to influenza B (7%).Estimated vaccine coverage was 73% in the elderly (≥65 years), 51% in non-elderly adults with medicalcomorbidities and 15% in children (<16 years) with medical comorbidities. The estimated vaccineeffectiveness in the target population was 13% (95% confidence interval (CI): -5% to 27%).
