Percentages of healthcare linens (HCLs) that were culture positive for Mucorales, Aspergillus, and other pathogenic molds during a longitudinal study at 1 hospital. Monthly testing was performed over 2 time periods: A, June 2016–January 2017 and B, June 2017–January 2018. No sampling was performed in July or December 2017. Culture data from the first time period were shared with the off-site laundry, which performed environmental remediation between February and May 2017. The hospital was also included in the multicenter study (represented as Center 3 in Figure 1), using data from June 2017. The horizontal line represents the 10% culture positivity cut-off to define HCL as hygienically clean.
