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 infected six patients with aspergillosis, killing two directly and leaving a third in intensive care for months. Both articles confirm a balcony near ongoing construction—part of a $900 million hospital redevelopment—was the likely source of the mould spores, which became airborne during work. NSW Health’s report, released on Friday, identified systemic failures, including a lack of fungal monitoring, and introduced reforms like increased air sampling and a surveillance committee. While both sources agree on the balcony’s role and the deaths linked to aspergillosis, discrepancies exist in timelines (four vs. three months for ICU stays), additional deaths (one source mentions sepsis-related mortality), and specific quotes or details about patient conditions. The investigation ruled out person-to-person transmission but could not pinpoint a single cause, emphasizing the risks immunocompromised transplant patients face from environmental mould exposure.

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, infecting six transplant patients
- Two patients died directly from the aspergillosis infection, while a third remains in intensive care four months after diagnosis (Article 1) or three months after diagnosis (Article 2)
- A balcony near construction work was identified as the probable source of the mould exposure, accessible by all six infected patients
- Construction on the hospital’s $900 million redevelopment was occurring 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 infection did not spread person-to-person but became airborne during construction activities
- The outbreak affected patients who were immunocompromised due to organ transplants (liver transplant in one case)
Points of Difference
Details reported by only one source:
- The fourth seriously ill patient remains in intensive care four months after diagnosis (no mention of three months in this source)
- The Sydney Local Health District gave affected families the chance to discuss findings with doctors and hospital management
- A third infected patient later died from 'multi-organ failure due to sepsis associated with a skin condition,' not the fungal infection itself
- The two deaths linked to aspergillosis were referred for a Serious Adverse Event Review (SAER) by senior transplant specialists
- The report found the balcony posed the 'greatest exposure risk' and explicitly stated the investigation could not determine a single conclusive cause
- One patient had spent 150 days in hospital prior to their liver transplant and infection
- The patient diagnosed with 'disseminated aspergillosis' was infected weeks after their transplant
- Deb Wilcox (Sydney Local Health District CEO) stated, 'We will never absolutely know the cause [of death], it's not possible to do so'
- The report identified a failure to implement a fungi monitoring program as a key issue
Contradictions
Conflicting information between sources:
- Article 1 states the fourth patient remains in intensive care four months after diagnosis, while Article 2 states this patient remains in intensive care three months after diagnosis
- Article 1 does not mention a third patient dying from sepsis-related complications, while Article 2 explicitly states this occurred
- Article 1 does not reference the 150-day hospital stay of the infected patient prior to transplant, which Article 2 details
- Article 2 attributes a quote to Deb Wilcox about the impossibility of determining the cause of death, while Article 1 does not include this quote
- Article 2 specifies the report found the balcony posed the 'greatest exposure risk,' while Article 1 does not use this exact phrasing
