1. INTRODUCTIONPrior to 2009, the national surveillance of <strong>in</strong>vasive pneumococcal disease (IPD) <strong>in</strong><strong>New</strong> <strong>Zealand</strong> was solely laboratory based, with diagnostic laboratories referr<strong>in</strong>g <strong>in</strong>vasiveisolates of Streptococcus pneumoniae to the Institute of Environmental Science and ResearchLtd (ESR) for serotyp<strong>in</strong>g and antimicrobial susceptibility test<strong>in</strong>g. This laboratory-basedsurveillance provided <strong>in</strong>formation on the basic epidemiology of IPD, and the serotypes andantimicrobial susceptibility of <strong>in</strong>vasive isolates. Information from this laboratory-basedsurveillance was published periodically. 1-5 In addition, between 2002 and 2007, annualreports on the antimicrobial susceptibility of isolates from IPD cases have been published onESR‟s surveillance website athttp://www.surv.esr.cri.nz/antimicrobial/streptococcus_pneumoniae.php.The first of this series of annual reports on IPD <strong>in</strong> <strong>New</strong> <strong>Zealand</strong> covered IPD <strong>in</strong> 2008 and wasbased on data available from ESR‟s national laboratory-based surveillance. 6 On 1 June 2008,the 7-valent pneumococcal conjugate vacc<strong>in</strong>e (PCV-7), Prevenar®, was added to the <strong>New</strong><strong>Zealand</strong> childhood immunisation schedule and IPD became a notifiable disease on 17 October2008. The 2009 IPD annual report was the first to be based on IPD notifications,supplemented with serotype and antimicrobial susceptibility data from ESR‟s laboratorybasedsurveillance of <strong>in</strong>vasive S. pneumoniae isolates. 7Data on the IPD cases notified <strong>in</strong> <strong>2010</strong> is presented <strong>in</strong> this report, along with trend data forrecent years.<strong>Invasive</strong> pneumococcal disease 1 September 2011<strong>in</strong> NZ, <strong>2010</strong>
