Dear All

The Australian Influenza Surveillance Report no.6 2011 which reports on
influenza activity up until 5 June 2011 has been produced.

Of note

*Levels of influenza-like illness (ILI) in the community continue
to remain low through sentinel general practitioner surveillance
systems, however ILI presentations to emergency departments have
increased.
*In recent weeks, notifications have increased most notably in
South Australia and Queensland, with some increases also observed in
most of the other jurisdictions.
*During this reporting period there were 574 laboratory confirmed
notifications of influenza, with Queensland and South Australia
reporting the highest number of notifications. The majority of virus
detections have been pandemic (H1N1) 2009, with co-circulation of
influenza B. The majority of the South Australian notifications this
fortnight have been influenza B (85%).There were no detections of
influenza A(H3N2) reported this fortnight.
*As at 27 May 2011, there have been 4,492 confirmed cases of
influenza reported to the National Notifiable Diseases Surveillance
System (NNDSS) in 2011, compared with 967 for the same period in 2010.
*The WHO has reported that worldwide influenza activity is low
and activity associated with the northern hemisphere influenza season
has finished. Seasonal transmission does not appear to have commenced in
most temperate countries of the southern hemisphere.

A summary version of this report will shortly be available on the web at
