Haemophilus influenzae type b (Hib) Case Surveillance Scheme
The Haemophilus influenzae type b (Hib) Case Surveillance Scheme (HCSS) is an enhanced surveillance system coordinated by NCIRS. The HCSS is designed to collect supplementary information not routinely available from the National Notifiable Diseases Surveillance System on cases of laboratory-confirmed invasive Hib disease. The HCSS was established in January 1994, following introduction of Hib vaccine onto the National Immunisation Program in 1993, with data collected retrospectively to 1 July 1993. Designated state and territory health department staff complete an enhanced surveillance form for each case of invasive Hib disease. Data collected include detailed information on immunisation status and disease, including information on past medical history of the case, outcome of the case and laboratory confirmation method.
