ACT Health has announced a formal review of isolation and triage protocols at Canberra Hospital after an investigation confirmed that a patient presenting with measles was not placed in appropriate isolation upon arrival, due to what staff described as 'competing clinical priorities' in the emergency department. The review, expected to deliver preliminary findings within 30 days, will examine whether current triage guidelines adequately flag infectious disease risks during periods of high patient load.

The incident, which came to light this week, has drawn criticism from infection control specialists who argue that measles — one of the most contagious infectious diseases known — demands immediate respiratory isolation regardless of departmental pressures. Canberra Hospital's Chief Medical Officer confirmed that contact tracing is underway for staff and patients who may have been exposed during the window in which the patient remained in an unsegregated area of the emergency department.

ACT Chief Health Officer Dr Kerryn Coleman said on Saturday that the territory's public health unit had identified a small number of close contacts and was working to confirm vaccination status. She urged anyone who visited Canberra Hospital's emergency department during the relevant period and who develops symptoms including fever, cough, or rash to contact their GP or call the healthdirect helpline rather than presenting directly to a hospital.

The case has reignited a broader national conversation about measles resurgence in Australia, where vaccination rates in some communities have slipped below the 95 percent threshold needed for herd immunity. The Australian Health Protection Principal Committee is expected to issue updated guidance for emergency departments on managing suspected measles presentations ahead of the upcoming winter respiratory illness season.

Health advocacy groups on Saturday called on all state and territory governments to conduct similar audits of their own hospital isolation procedures. The Royal Australasian College of Emergency Medicine said it would work with ACT Health to develop clearer decision-support tools for triage nurses, noting that measles notifications nationally have trended upward over the past 18 months.
