Candida auris Spreads to Hospital Staff Gloves, Gowns

The multidrug-resistant yeast, Candida auris, was frequently transferred from hospitalized patients to the gloves and gowns of healthcare personnel (HCP), according to research published in Infection Control & Hospital Epidemiology. This transfer occurred even when patients did not exhibit visible signs of colonization or infection, highlighting a significant pathway for the spread of this concerning pathogen within healthcare settings. The study observed extensive colonization of C. auris at multiple body sites on patients, leading to shedding onto environmental surfaces and subsequent contamination of HCP personal protective equipment (PPE).

Researchers collected samples from 20 patients colonized or infected with C. auris and from the HCP caring for them over a 14-day period. They found that C. auris was present on the skin and in bodily fluids of patients, and this presence frequently resulted in contamination of the gloves and gowns worn by healthcare workers. The study's findings underscore the challenges in preventing the transmission of C. auris, a pathogen known for its ability to persist on surfaces and resist common disinfectants. The frequent transfer to PPE suggests that standard infection control practices may not be entirely sufficient to contain its spread, particularly in high-risk environments like intensive care units.

Candida auris is a serious global health threat due to its resistance to antifungal medications, its tendency to cause outbreaks, and its ability to survive on surfaces for extended periods. First identified in 2009, it has since spread to numerous countries, causing severe invasive infections, including bloodstream infections, wound infections, and ear infections. The yeast's multidrug resistance makes treatment options limited and often less effective, contributing to higher mortality rates among infected individuals. The study's focus on the transfer to HCP PPE provides critical insights into the dynamics of C. auris transmission and emphasizes the need for enhanced vigilance and potentially revised protocols for disinfection and PPE management in hospitals.

The implications of these findings are substantial for hospital infection control programs. The frequent contamination of gloves and gowns indicates that even with the use of PPE, transmission can occur if the PPE becomes contaminated during patient care. This necessitates a thorough review of donning and doffing procedures, as well as the frequency of PPE changes. Furthermore, the study's observation of shedding from patients without apparent signs of infection suggests that screening protocols may need to be re-evaluated to identify asymptomatic carriers who can still contribute to environmental contamination and transmission. The research team stressed the importance of rigorous environmental cleaning and disinfection protocols to reduce the persistence of C. auris on surfaces within patient rooms and common areas. The study's detailed analysis of transfer events provides actionable data for healthcare facilities aiming to curb the spread of this resilient and dangerous yeast.
