Overview

They are common in most adult people, with up to 20 percent of the population having one of these infections at any given moment.

Epidemiology and demographics

Prevalence

  • Worldwide, the prevalence of dermatophytposis is 20000-25000 per 100,000 persons.[1]

Incidence

  • Worldwide, the incidence of dermatophytosis ranges from a low of 10000 per 100,000 persons to a high of 15000 per 100,000 persons.

Case-fatality rate

Age

Gender

  • Dermatophytosis is more prevalent in women than in men.[2]

Race

Geographic distribution

  • In Europe, the countries reporting the highest incidence of M. canis infections (Tinea capitis) are mainly in the Mediterranean but also bordering countries like Austria, Hungary, Germany and Poland.[3]
  • The largest overall increase with anthropophilic dermatophytes has been noted with Trichophyton tonsurans mainly in the UK and with Trichophyton soudanense and Microsporum audouinii in France.[4]
  • Large-scale studies on onychomycosis conducted in the US and Canada in the late 1990s showed a prevalence rate of 14000 per 100,000 persons and 8000 per 100,000, respectively. In Europe, the prevalence rate is even more variable, with 2700 per 100,000 in the UK and Spain, 8400 per 100,000 in Finland, 12400 per 100,000 in Germany and 16800 per 100,000 in France in a more recent study.
