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 a balcony near ongoing construction identified as the likely source. Both articles confirm six transplant patients were exposed to aspergillosis mould, though ABC specifies the third death was due to sepsis from a skin condition rather than the mould itself. NSW Health’s report, released on Friday, pinpoints the balcony—accessible to all infected patients—as the probable exposure site, attributing the outbreak to airborne spores generated during adjacent construction for the hospital’s $900 million redevelopment. While both sources agree on the balcony’s role, ABC emphasizes the failure of the hospital’s fungi monitoring program and the uncertainty in directly attributing deaths to the mould, whereas NEWSCOMAU focuses on the ongoing impact on affected families and the fourth patient’s prolonged intensive care. The state has accepted reforms, including stricter air sampling and a fungal surveillance committee, to prevent future incidents.
✓ 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 were diagnosed with aspergillosis in November–December 2025, with two deaths directly attributed to the infection and a third patient remaining in intensive care for months
- 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, recommending increased air sampling and a fungal surveillance committee
- The outbreak involved immunocompromised patients, including one who had spent 150 days in hospital prior to infection and another with disseminated aspergillosis after a liver transplant
- The two deaths were referred for a Serious Adverse Event Review (SAER) by senior transplant specialists
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
- The third infected patient died from 'multi-organ failure due to sepsis associated with a skin condition,' not the fungal infection itself
- The report found the balcony posed the 'greatest exposure risk' and construction works made spores airborne
- Deb Wilcox (Sydney Local Health District CEO) stated, 'We will never absolutely know the cause [of death],' emphasizing uncertainty in attributing deaths solely to the mould
- The hospital’s fungi monitoring program was identified as a failure in the report, with all four recommendations accepted by NSW Health
- The patient in intensive care had a liver transplant in November 2025 and was diagnosed with 'disseminated aspergillosis' in December 2025
Contradictions
Conflicting information between sources:
- NEWSCOMAU states the fourth patient remains in intensive care four months after diagnosis, while ABC does not specify the duration for this patient beyond 'three months' for another case
- ABC notes the third death was from sepsis related to a skin condition, not the mould, but NEWSCOMAU does not mention this distinction
- NEWSCOMAU does not reference the $900 million redevelopment figure or the specific role of construction in making spores airborne, which ABC details
