Are reduced concentrations of chlorine-based disinfectants effective against Candida auris?

Chlorine-based disinfectants are commonly used in rooms of patients with Candida auris, but there is uncertainty regarding optimal concentrations that provide efficacy while minimizing the potential for adverse effects. We found that 2 chlorine-based disinfectants were effective against C auris with 1 minute of contact time at concentrations of 4,000 parts per million or higher. Lower concentrations were effective only with increased contact times that may not be practical in real-world health care settings.
