High Frequency of Self-Diagnosis and Self-Treatment in a Nationally Representative Survey about Superficial Fungal Infections in Adults—United States, 2022
Abstract
Data about the prevalence, diagnosis, treatment, and public knowledge of superficial fungal infections in the United States are scarce. These infections are a growing concern given the emergence of antifungal drug resistance. We analyzed data from a national survey of nearly 6000 U.S. adults. Overall, 114 (2.7%) participants reported having ringworm and 415 (10.0%) reported a fungal nail infection in the past 12 months; 61.4% of participants with any superficial fungal infection were self-diagnosed. Most patients (55.5%) used over-the-counter antifungals. The common nature of superficial fungal infections and the high rates of self-diagnosis and treatment indicate that community education about these infections should be considered a public health priority.
