Australian Influenza Activity Update - week ending 22 May 2015
- Australia is currently in the inter-seasonal period for influenza. Overall influenza activity is low and stable, but higher than at the same time in previous years.
- Influenza activity across jurisdictions is variable. Influenza activity is higher in most jurisdictions compared to the same period in previous years.
- This year to date, influenza A is the predominant circulating virus type; of those viruses where subtyping data are available, influenza A(H3N2) is the most common. Influenza B is circulating at increasing levels in recent weeks.
- Of the limited number of isolates that have been further characterised for similarity with the vaccine components, influenza A viruses appear to be well matched. Over 80% of the influenza B viruses characterised are a match to the trivalent vaccine strain; the remaining influenza B viruses matching the additional strain in the quadrivalent vaccine.
- Influenza-like illness (ILI) levels detected through the sentinel GP ILI surveillance system are increasing. In the most recent fortnight, rhinovirus infection was the most common cause of ILI detected.
