In a representative sample of 20 000 individuals aged 1 to 74 years in the northeastern United States in the late 1970s, the US Health and Nutrition Examination Survey found the overall prevalence of nail fungal infections to be 2.18%.1 More recently, population-based questionnaire surveys conducted in the United Kingdom2 and Spain3 found the overall prevalence of onychomycosis to be 2.7% (males, 2.8% and females, 2.6%) and 1.7% (males, 0.8% and females, 1.8%), respectively.
