[Wishart, Michael]

Dear all,

The Australian Influenza Surveillance Report no.8 2011 which reports on
influenza activity up until 8 July 2011 has been produced.

Of note:
Levels of influenza-like illness (ILI) in the community continued to
increase through both sentinel general practitioner surveillance systems
and ILI presentations to emergency departments.
Notifications have continued to rise nationally, with increases most
notable in South Australia, Queensland and New South Wales.
During this reporting period there were 1,555 laboratory confirmed
notifications of influenza, with Queensland reporting the highest number
of notifications, followed by New South Wales and South Australia. The
majority of virus detections have been pandemic (H1N1) 2009, with
co-circulation of influenza B.
Influenza B in South Australia has continued to represent the majority of
their notifications (80%), and also accounted for over half of all
influenza B reported nationally over this period. Queensland and New SouthWales have reported mostly pandemic (H1N1) 2009 with some co-circulation
of influenza B.
As at 8 July 2011, there have been 7,488 confirmed cases of influenza
reported to the National Notifiable Diseases Surveillance System (NNDSS)
in 2011, compared with 1,294 for the same period in 2010.
The WHO has reported that influenza activity in the temperate countries ofthe northern hemisphere is at baseline inter-seasonal level. Influenza
activity in the temperate countries of the southern hemisphere has
increased in recent weeks.
