Fungal outbreak at Sydney hospital linked to construction-related mould exposure
Consensus Summary
A fungal outbreak at Royal Prince Alfred Hospital’s transplant unit in late 2025 killed two patients and critically infected four others, with aspergillosis spores likely spreading from a balcony near ongoing construction. Both sources confirm the balcony—accessible to all six infected patients—was the probable source, though NSW Health’s report notes no single definitive cause was proven. The outbreak occurred during a $900 million hospital redevelopment, and spores became airborne during construction, posing risks to immunocompromised transplant patients. NSW Health has since introduced reforms, including stricter air sampling and a fungal surveillance committee, after the report highlighted failures in monitoring programs. While both articles agree on the balcony’s role and the deaths linked to the infection, ABC provides additional details about patient timelines and causes of death, including a third fatality attributed to sepsis rather than the mould. NEWSCOMAU emphasizes the prolonged ICU stay of one patient and family discussions with hospital management, but lacks some specifics on patient conditions or the broader investigation findings.
✓ Verified by 2+ sources
Key details reported by multiple sources:
- Royal Prince Alfred Hospital’s transplant unit (Ward 9E) experienced a fungal outbreak in late 2025 linked to aspergillosis mould, killing two patients and seriously infecting four others
- A balcony near construction work was identified as the probable source of the mould exposure, accessible by all six infected patients
- Six transplant patients (all in Ward 9E) were diagnosed with aspergillosis between November and December 2025, with one patient remaining in intensive care as of mid-2026
- Construction on the hospital’s $900 million redevelopment was underway adjacent to the balcony during the outbreak
- NSW Health released a final report on the outbreak on Friday, outlining reforms including increased air sampling and a fungal surveillance committee
- The two deaths directly linked to the fungal infection have been referred for a Serious Adverse Event Review (SAER)
- Aspergillus spores became airborne during construction activities, posing a risk to immunocompromised patients
Points of Difference
Details reported by only one source:
- The fourth seriously ill patient remains in intensive care four months after diagnosis (as of report release date)
- Affected families were given the chance to discuss findings with doctors and hospital management
- One patient had a liver transplant and spent 150 days in hospital prior to infection, diagnosed with 'disseminated aspergillosis' weeks after the transplant
- A third infected patient later died from 'multi-organ failure due to sepsis associated with a skin condition,' not the fungal infection
- Sydney Local Health District Chief Executive Deb Wilcox stated, 'We will never absolutely know the cause [of death], it's not possible to do so and it's really just on the balance of the facts in front of us'
- The report found a failure to implement a fungi monitoring program, with all four recommendations accepted by health authorities
- The balcony was located near construction works and posed the greatest exposure risk for the fungal outbreak in late 2025
- The investigation team was unable to determine a single conclusive cause of the outbreak, but the balcony and construction posed the greatest risk
Contradictions
Conflicting information between sources:
- NEWSCOMAU states the fourth seriously ill patient has been in intensive care for four months, while ABC does not specify the duration for the patient still in ICU
- ABC mentions one patient died from 'multi-organ failure due to sepsis associated with a skin condition,' not the fungal infection, but NEWSCOMAU does not clarify this distinction for the third death
- ABC reports the patient in ICU had a liver transplant and spent 150 days in hospital prior to infection, while NEWSCOMAU does not provide this level of detail
