  • Influenza virus detections and notifications are relatively steady, with influenza B (71%) and influenza A/H3N2 (26%) viruses dominating detections.
  • Overall non-influenza respiratory virus detections decreased marginally, but respiratory syncytial virus activity continues to increase steeply.


  • Gastroenteritis presentations to sentinel GPs and EDs remain relatively stable. Rotavirus detections continue to increase, while norovirus activity is variable.

Varicella and Viral Rashes

  • Shingles and chickenpox presentations to sentinel EDs and GPs are around baseline levels.
  • No cases of rubella were notified.
  • Several additional cases of mumps were reported among boarders at two schools linked to an outbreak in the Kimberley region, where transmission may now have been controlled.
