The Paediatric Active Enhanced Disease Surveillance (PAEDS) network is a hospital-based active surveillance system employing prospective case ascertainment for selected serious childhood conditions, particularly vaccine preventable diseases and potential adverse events following immunisation (AEFI). PAEDS data is used to better understand these conditions, inform policy and practice under the National Immunisation Program, and enable rapid public health responses for certain conditions of public health importance. PAEDS enhances data available from other Australian surveillance systems by providing prospective, detailed clinical and laboratory information on children with selected conditions.

PAEDS aims:

  • to actively collect detailed information that isn’t available from other surveillance systems, about children hospitalised with vaccine-preventable diseases and potential adverse events following vaccination
  • to inform vaccination policy and practice, including vaccine safety
  • to improve child health outcomes.


PAEDS is a network of clinicians and public health researchers in six Australian tertiary paediatric hospitals which also works with several associate investigators, collaborators and contributors.  PAEDS is funded by the Australian Government Department of Health with contributions from the state health departments of New South Wales, Victoria, South Australia, Western Australia, Queensland and the Northern Territory. Funding from NHMRC grants also supplements certain surveillance activities. PAEDS is also under the oversight of the PAEDS Reference Group, composed of representatives from all participating Departments of Health and independent expert groups.

The conditions included in PAEDS are acute flaccid paralysis, intussusception, varicella and herpes zoster, pertussis, febrile seizures and acute childhood encephalitis.

PAEDS annual report 2015

Prospective hospital-based surveillance for serious paediatric conditions

This is the second annual report of the Paediatric Active Enhanced Disease Surveillance (PAEDS) network and summarises data collected in 2015. PAEDS historical data for 2007–2014, including impacts and outcomes, were reported in the PAEDS 2014 inaugural report.
