This is a randomized, controlled, open-label trial of effect of 10% povidone iodine intranasal antisepsis on the detection of Candida auris.
The investigators will assess the effect of nasal antisepsis with 10% povidone iodine on nasal and skin colonization and environmental contamination with C. auris. This topical, widely used antiseptic agent is available over the counter in the U.S. It was chosen for its excellent safety profile, history as a nasal antiseptic for Staphylococcus aureus decolonization, proven in vitro activity against C. auris and feasibility in acute care and nursing home populations. This study will be conducted at 2 long-term acute care hospitals and one acute care hospital in the Chicago, IL region. Participants will first undergo intranasal screening for current C. auris colonization. Participants who grow C. auris from an anterior nares sample will be assigned 1:1 at random to receive intranasal povidone iodine (10% povidone iodine twice daily for up to 5 days) or control (no intranasal treatment). The investigators will perform all study visits during the participants' hospitalization at a participating facility. Samples will be collected on 5 days during the intervention week, then once weekly thereafter. Participants may participate for up to 8 study visits after randomization or until facility discharge, whichever occurs sooner.

RECRUITINGDetection of C. auris from the anterior nares
Culture detection of C. auris from anterior nares on intervention day 5.
Time frame: Through study completion and data analysis in three years (2028)
Detection of C. auris from body sites other than anterior nares
Culture detection of C. auris from body sites other than anterior nares. The investigators will compare detection of C. auris by culture during intervention vs post-intervention periods.
