Relationship between Staphylococcus aureus Colonization and Face Mask-associated Adverse Cutaneous Reactions during the COVID-19 Pandemic

ABSTRACT

Background@#Adverse reactions on the skin due to face masks are well documented following the COVID-19 pandemic. This study aims to investigate Staphylococcus aureus colonization in relation to face mask-associated adverse cutaneous reactions (FMACR)@*Methods@#This was a case-control study involving adult patients attending dermatology clinic, Hospital Tengku Ampuan Afzan, Pahang, Malaysia. FMACR was determined via a structured interview. Subjects and healthy controls were matched for age and gender. Skin swabs from the alar crease and glabella were obtained and cultured. The possible risk factors for FMACR including type of mask, frequency of change, average duration of use, and skin care practices were also attained. @*Results@#A total of 114 adult participants, which consisted of 57 case and 57 control were recruited. Itching was the most frequent (32; 32.4%) FMACR noted, followed by acne (31; 31.4%) and rashes (22; 22.2%). The presence of facial dermatoses and oily skin type increased the risk of FAMCR (adjusted OR=5.96, 95% CI (1.96,18.12), p=0.002 and adjusted OR=1.94, 95% CI (0.28,13.28), p=0.009) respectively. Cosmetic use was associated with lower risk of FMACR, (adjusted OR=0.16, 95% CI (0.05, 0.56), p=0.004). No significant association was noted between S. aureus skin colonization and FMACR (p=0.409). @*Conclusion@#Staphylococcus aureus skin colonization was not associated with FMACR. Risk factors for FMACR were the presence of facial dermatoses and oily skin type while cosmetic use appears to have a protective effect.
