Invasive Pneumococcal Disease in New Zealand, 2010

SUMMARYA 4-dose schedule of the 7-valent pneumococcal conjugate vaccine (PCV-7), Prevenar®, wasadded to the New Zealand childhood immunisation schedule in June 2008, with a catch-upprogramme for all children born on or after 1 January 2008. Since 17 October 2008, invasivepneumococcal disease (IPD) has been notifiable to medical officers of health under theHealth Act 1956.In this report, the data presented for 2009 and 2010 is based on IPD case notificationssupplemented with serotype and antimicrobial susceptibility data from ESR‟s nationallaboratory-based surveillance of invasive Streptococcus pneumoniae isolates. Data for earlieryears is solely from ESR‟s laboratory-based surveillance. For this laboratory-basedsurveillance, diagnostic microbiology laboratories are requested to refer all invasive isolatesof S. pneumoniae to ESR for serotyping and antimicrobial susceptibility testing.There were 535 cases of IPD notified in 2010, which equates to a rate of 12.2 cases per100 000. A S. pneumoniae isolate from an invasive site was received at ESR for serotypingand susceptibility testing for 514 (96.1%) of the notified cases.The incidence of IPD in infants
