Candida Auris Screening and Infection Control

Screening Recommendations

  • The Centers for Disease Control and Prevention recommends screening for Candida auris in high-risk patients, with axilla and groin composite swabs being the preferred sampling method using specialized culture media or PCR-based detection 1
  • Close contacts of known C. auris colonized or infected patients should be screened for C. auris colonization 1

Preferred Screening Methods

  • Composite swabs of the axilla and groin are the recommended sampling sites for C. auris screening 1
  • Laboratory testing options include specialized salt-containing media or chromogenic agars for culture-based detection 1

Screening Protocol Implementation

  • Patients who are confirmed to be colonized with C. auris should be isolated until screening results are available 1
  • For contact tracing, all close contacts of confirmed cases should be screened for C. auris colonization 1
  • Patients should be considered negative only after 3 consecutive negative screens taken at least 24 hours apart 1

Infection Control Considerations

  • Environmental cleaning requires sporicidal disinfectants (hydrogen peroxide, peracetic acid-based, or chlorine-based) as quaternary ammonium compounds have poor activity against Candida species 1
