Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment the UK Health Security Agency has made of the fatality rate associated with invasive Candidozyma auris infection.

The UK Health Security Agency (UKHSA) routinely monitors the candidozyma auris situation in England and shares information with hospitals and health system partners so they can put in place timely measures to protect patients.

There is no published UKHSA data on fatality associated with invasive candidozyma auris infection, however the UKHSA is closely monitoring situation in England with improved surveillance, including the attributable and all-cause mortality for candidozyma auris.

Candidozyma auris cases have increased in the United Kingdom in recent years. Our most recent epidemiological commentary states that between January 2013 and April 2025 inclusive, a total of 800 candidozyma auris cases, both infections and colonisations, where people are carrying the organism on their skin without any symptom or illness, were reported in England. Reassuringly, the vast majority of these are colonisations, with 87% being colonised, 12% being invasive, and 1% of an unknown specimen type. Colonisation without invasive infection has a negligible risk of negative health outcomes. The UKHSA is currently validating a process for reporting mortality figures as part of future routine data releases.
