What is onychomycosis?
Onychomycosis is what most people would call a nail fungus. It is also known as dermatophytic onychomycosis or tinea unguium. It is a fungal infection of the nail. It can occur in fingernails or toenails, but it is most common in the toenails. Around one in ten people suffer from it at some time or other.
What causes nail fungal infections?
They can be caused by pathogens such as dermatophytes, Candida, and nondermatophytic molds. Dermatophytes are the most common cause in temperate Western countries. In hot, humid climates, Candida and nondermatophytic molds are more likely to be the cause.
People older than 65 sometimes get fungal infections due to other kinds of molds because they have less resistance.
