what is onychomycosis
Onychomycosis (tinea unguium) is a fungal infection of the nail bed, matrix or plate. Toenails are affected more often than finger-nails. 1, 2 Onychomycosis accounts for one third of integumentary fungal infections and one half of all nail disease. 1 Tinea unguium occurs primarily in adults, most commonly after 60 years of age. The incidence of this infection is probably much higher than the reported 2 to 14 percent.
