The ICU Device That Spread Candida auris
- What: A UK hospital investigation traced part of a Candida auris outbreak to reusable axillary temperature probes that were difficult to clean.
- Where: A neurosciences intensive care unit in the UK.
- When: Between 2015 and 2017.
In a UK neurosciences intensive care unit, the key link in a Candida auris outbreak turned out to be something ordinary: reusable axillary temperature probes.
Between 2015 and 2017, clinicians dealt with a hard-to-control cluster of this emerging fungus in a hospital setting. Patients were identified with C. auris despite routine infection-control measures already being in place. The pattern suggested that whatever was helping it move through the unit was not obvious, and not limited to direct patient contact.
The investigation eventually pointed to reusable probes placed in the armpit to monitor temperature. They were used frequently, close to the skin, and stored in covers that proved difficult to clean completely. That mattered because C. auris is unusually good at staying in the environment. Unlike many organisms that fade quickly once off the body, this fungus can persist on hospital surfaces for days to weeks, giving it more chances to be picked up and passed along.
What made the episode important was not just the traced source. It was the way it clarified the problem. A device that seemed routine, low-drama, and easy to overlook became a practical demonstration of how C. auris can survive in real clinical spaces and keep circulating even when staff are already taking standard precautions seriously.
After the probes were withdrawn, the hospital strengthened its response with enhanced cleaning and patient isolation. The outbreak did not instantly become a simple story, and it would be too strong to imply one object alone explained every transmission. But the probe link gave investigators a concrete route of spread they could act on, and it helped reshape how hospitals think about reusable equipment in high-risk units.
The lasting implication is specific. In modern hospitals, the challenge is not only the pathogen itself. It is the gap between a device being reusable in theory and being reliably clean in practice. In this case, a temperature probe made that gap visible.
