5% of onychomycotic infections are due to mixed infections (1)

Exotic fungal species may result after foreign travel, and normally non-pathogenic organisms may be found causing disease in immuno-compromised patients.

Onychomycosis accounts for approximately 50% of reported nail disorders:

  • population-based prevalence of onychomycosis as 4.3% in Europe and North America and found it was more prevalent in men in North America and Europe and in women in South America (2)
  • onychomycosis is more common in toenails than in fingernails - toenail infections to be 10 times more common than fingernail infections
  • evidence suggests infection was most commonly caused by the dermatophyte fungal organism Trichophyton rubrum (44.9%), followed by yeasts (21.2%), other dermatophytes (20.1%), and moulds (13.3%) (2)
