Fungal Outbreak at Sydney Hospital Linked to Construction, Claims Two Lives

A fungal infection outbreak at Sydney’s Royal Prince Alfred Hospital (RPA) linked to ongoing redevelopment work has tragically resulted in the deaths of two patients. Six patients in the hospital’s transplant unit were affected by the outbreak, which occurred between October and December 2025.

What Caused the Outbreak?

The infection was caused by Aspergillus, a common mold found in environments such as soil, dust, and damp areas. While typically harmless to individuals with healthy immune systems, Aspergillus can pose a serious threat to those with weakened immunity, particularly transplant recipients. NSW Health provides detailed information on Aspergillus and associated infections.

Hospital Response and Safety Measures

Following the identification of the fungal cluster, RPA Hospital and Sydney Local Health District implemented a series of safety measures. These included:

• A thorough deep clean of the affected ward.
• Upgrades to air filtration systems to reduce airborne mold spores.
• Comprehensive air testing to monitor air quality and identify potential sources of contamination.
• Proactive administration of antifungal medication to at-risk patients, following clinical consultation.

Patients were temporarily relocated from the transplant ward while these remedial efforts were underway. An expert panel, convened by NSW Chief Health Officer Kerry Chant, assessed the situation and declared the ward safe to reopen on February 9th.

Redevelopment Link and Ongoing Safety

Health authorities have indicated that the $940 million redevelopment currently underway at RPA Hospital is likely the source of the fungal contamination. Details of the RPA Hospital redevelopment project can be found on the Sydney Local Health District website. The hospital has a long-standing reputation for excellence in transplant surgery, with nearly 60 years of experience in kidney transplants and 40 years in liver transplants.

“RPA is a leader in transplant surgery… We reassure patients and the community that RPA Hospital continues to be a safe place for care, and we have put in place robust policies and procedures to help prevent any further fungal infections,” a Sydney Local Health District spokesperson stated.

Understanding Aspergillus Infections

Aspergillus is a ubiquitous fungus, meaning it’s commonly found in the environment. Most people breathe in Aspergillus spores daily without experiencing any ill effects. However, for individuals with compromised immune systems – such as those undergoing organ transplantation, receiving chemotherapy, or living with HIV/AIDS – Aspergillus can cause a range of infections, including:

• Aspergillosis: A general term for infections caused by Aspergillus.
• Invasive Aspergillosis: A severe, life-threatening infection that typically affects the lungs but can spread to other organs.
• Allergic Bronchopulmonary Aspergillosis (ABPA): An allergic reaction to the fungus that affects the airways.

Key Takeaways

• A fungal outbreak at RPA Hospital resulted in two patient deaths.
• The outbreak was linked to Aspergillus mold and ongoing hospital redevelopment.
• The hospital implemented stringent safety measures to address the contamination.
• Aspergillus poses a particular risk to immunocompromised individuals.
• RPA Hospital maintains it is a safe environment for patient care.

The incident highlights the importance of robust infection control measures during hospital construction and the vulnerability of immunocompromised patients to environmental pathogens. Ongoing monitoring and preventative strategies will be crucial to ensuring patient safety at RPA Hospital and other healthcare facilities undergoing similar redevelopment projects.
