Invasive pneumococcal disease surveillance Australia, 1 July to 30 September 2014.

Invasive pneumococcal disease (IPD) is caused by the bacterium Streptococcus pneumoniae and results in conditions such as pneumonia, bacteraemia and meningitis. There are currently more than 90 serotypes recognised worldwide, approximately half of which are found in Australia where IPD has been a nationally notifiable disease since 2001. This quarterly report documents trends in notified cases of IPD occurring in Australia in the 3rd quarter of 2014 (1 July to 30 September 2014). In this quarterly report, 3 age groups have been selected for focused analyses. These age groups align with groups that carry the greatest burden of disease and against which the National Immunisation Program is targeted. The data in this report are provisional and subject to change as laboratory results and additional case information become available.
