In 2007, the Victorian influenza season exceeded normal seasonal activity thresholds. The average rate of influenza-like illness (ILI) reported by general practitioners (GPs) participating in sentinel surveillance was 9.0 cases per 1,000 consultations, peaking at 22 cases per 1,000 consultations in mid-August. The average ILI rate reported by the Melbourne Medical Locum Service (MMLS) was 11.5 per 1,000 consultations over the season. The MMLS ILI rate peaked at 30 per 1,000 consultations at the same time as peak rates were reported by GPs, with a secondary peak observed three weeks later (22 cases per 1,000 consultations). Influenza cases notified to the Victorian Department of Human Services peaked in mid-August with a secondary peak of influenza A in early September. Of the influenza positive swabs collected by GPs and among those collected throughout the state, 92% were type A and 8% were type B. The most common strains identified in Victoria in the 2007 influenza season were A/ Brisbane/10/2007-like followed by A/Solomon Islands/3/2006-like. While neither virus strain was specifically included in the 2007 Australian influenza vaccine, reasonable cross protection was afforded by the strains in the vaccine.
2007年，维多利亚州的流感季节超过了正常季节性活动阈值。参与哨点监测的全科医生（GP）报告的流感样疾病（ILI）平均发病率为每1000次咨询9.0例，8月中旬达到峰值，每1000次咨询22例。墨尔本医疗临时服务机构（MMLS）报告的本季节ILI平均发病率为每1000次咨询11.5例。MMLS的ILI发病率在与全科医生报告的峰值同时达到每1000次咨询30例的峰值，三周后出现第二个峰值（每1000次咨询22例）。向维多利亚州人类服务部通报的流感病例在8月中旬达到峰值，甲型流感在9月初出现第二个峰值。在全科医生采集的以及全州采集的流感阳性拭子中，92%为甲型，8%为乙型。2007年流感季节在维多利亚州鉴定出的最常见毒株是A/布里斯班/10/2007样毒株，其次是A/所罗门群岛/3/2006样毒株。虽然这两种病毒毒株都未被特别列入2007年澳大利亚流感疫苗中，但疫苗中的毒株提供了合理的交叉保护。
