| Abstract: | This study aimed to characterize commensal microbiota on the skin before and after wearing masks, and to characterize the microbiota on the surface of used masks after 1 week of drying. From the 13 human subjects (age range, 19–26 years), mean bacterial concentrations of (6.1 ± 11.0) × 105 and (1.0 ± 1.4) × 106 colony-forming units (CFU)/mL were recovered from the skin of the buccal areas wiped with a sterile cotton swab before and after wearing non-woven fabric masks for 8 h, respectively. Furthermore (3.4 ± 4.9) × 104 CFU/mL of bacteria were recovered from the mask surfaces. The bacteria contained in the masks, which consisted mainly of Cutibacterium acnes and Staphylococcus epidermidis/aureus, virtually disappeared after drying the masks indoors for 1 week. |
