摘要：The 2010 influenza season was moderate overall, with more laboratory-confirmed cases than in earlieryears (with the exception of 2009). That said, self-reported influenza-like illness (ILI) was equalto or lower than 2008 and earlier years. In 2010, the number of laboratory-confirmed notificationsfor influenza was 0.8 times the 5-year mean. High notification rates were reflected in an increase inpresentations with ILI to sentinel general practices and emergency departments. Notification rateswere highest in the 0–4 year age group. Infections during the season were predominantly due toinfluenza A(H1N1)pdm09, with 90% of notifications being influenza A (56% A(H1N)1pdm09, 30%A(unsubtyped) and 4% A(H3N2)) and 10% being influenza B. The A(H1), A(H3) and B influenzaviruses circulating during the 2010 season were antigenically similar to the respective 2010 vaccinestrains. Almost all (99%) of the circulating influenza B viruses that were analysed were from theB/Victoria lineage.
