BACKGROUND: Tinea pedis is a common chronic skin disease; the role of contaminated clothes as a possible source of infection or re-infection has not been fully understood. The ability of ultraviolet light to inactivate microorganisms has long been known and UV is used in many applications.
OBJECTIVES: To evaluate the effectivity of sun exposure in reducing fungal contamination in used clothes.
METHODS: Fifty-two contaminated socks proven by fungal culture from patients with tinea pedis were studied. The samples were divided into two groups: group A underwent sun exposure for 3 consecutive days and group B remained indoors. At the end of each day fungal cultures of the samples were performed.
RESULTS: Overall, there was an increase in the percentage of negative cultures with time. The change was significantly higher in socks that were left in the sun (chi-square for linear trend = 37.449, P < 0.0001).
CONCLUSIONS: Sun exposure of contaminated clothes was effective in lowering the contamination rate. This finding enhances the current trends of energy saving and environmental protection, which recommend low temperature laundry.
