Cause of death

Streptococcus pyogenes and parechovirus infection

AI-generated summary

An eight-month-old boy in state care died from Streptococcus pyogenes and parechovirus infection. He presented to hospital twice before death with fever and ear infection symptoms. On first presentation (2 September), he was assessed as having likely viral otitis media with normal observations; discharge was appropriate. On second presentation (4 September morning), observations were mildly abnormal but improved with paracetamol; oral antibiotics were started. He was discharged home with safety-netting for return if worse. He deteriorated rapidly that evening and presented in cardiac arrest, resuscitation efforts unsuccessful. The coroner found no clinical failings: sepsis recognition is genuinely difficult in young children who may compensate well until sudden collapse; the presentations lacked fever and classic septic signs; the prescribed antibiotic was appropriate; and imaging/transfer were not indicated at the time. The rapid deterioration characteristic of invasive Group A Strep in young infants occurred between discharge and readmission.

Contributing factors

  • Young age (8 months old) with rapid disease progression
  • Viral coinfection (parechovirus) creating opportunity for bacterial invasion
  • Compensatory physiological mechanisms masking sepsis signs in young infants
  • Absence of fever at final pre-deterioration assessment
  • Short interval between discharge and deterioration limiting opportunity for observation

Coroner's recommendations

  1. WACHS to implement the Department of Health's Statewide Paediatric Sepsis Pathway (PSP) state-wide, which commenced rollout in April 2025
  2. Update the PARROT observation chart to link to the new PSP
  3. Implement education package accompanying new sepsis recognition tools
  4. Implement tool based on National Institute for Health and Care Excellence Guidelines to aid recognition of sepsis in children, particularly for staff with less paediatric experience
  5. Communities staff to ensure adherence to any Court outcomes in future cases regarding child placement and rehabilitation program early departure
