Onychomycosis: Types of Nail Fungus, Causes, and Symptoms

Onychomycosis describes a fungal infection of the nail, which can be caused by dermatophytes such as the fungus Trichophyton rubrum.

Symptoms: Signs that there is a fungal infection taking place include: onycholysis (separation of the nail plate from the nail bed), discoloration (white or yellow), and/or an accumulation of subungual debris under the nail (the odiferous gooey stuff that collects under an infected nail).

Causes: People with lowered immune system, such as those receiving chemotherapy, are at higher risk for infections. Nurses, doctors, dental hygienists, and those who generally either have their hands in water often or wear gloves (which promote a moist, sweaty environment) are more likely to encounter fungal infections in their fingernails.
