  • Description:

    Candida auris is a multidrug-resistant yeast causing outbreaks in healthcare settings. Stopping the spread of C. auris requires rapid identification of healthcare facilities at risk of higher transmission to help targeted implementation of infection control measures. We used data collected during public health investigations to quantify transmissibility of C. auris by type of healthcare facility.


    In two states, 3,159 patient swabs were collected during 96 C. auris point prevalence surveys conducted at 36 inpatient healthcare facilities in November 2016 and April 2018. We estimated facility transmissibility and facility reproduction number (number infected by one index colonized patient per day, and per stay, respectively, at the facility) of C. auris based on estimated colonization pressure, a count of newly colonized patients between successive surveys at the same facility, and mean lengths of stay at facilities (estimated from CMS administrative data). The results were summarized by facility type: acute care hospital (ACH), long-term acute care hospital (LTACH) or ventilator unit at skilled nursing facility (VSNF), and were compared with previous estimates for transmissibility of carbapenem-resistant Enterobacteriaceae (CRE).


    Swabs were collected from 13 ACHs, 12 LTACHs, and 11 VSNFs. The C. auris facility reproduction number may exceed the critical value of 1 in both ACHs and VSNFs, and may exceed that for CRE in ACHs (table).


    Transmissibility of C. auris is comparable to that of CRE. The transmissibility within VSNFs emphasizes their potential role as amplifiers in the outbreak. Understanding transmissibility by facility type helps evaluate the potential impact of interventions in various settings.
