​Onychomycosis (Fungus on toenails) is a very common problem among the population in North America. According to the National Institutes of Health in the United States In North America, the incidence of onychomycosis is up to 14% in the general population, with fungal infection responsible for 50% of all nail diseases. Here in Canada, the incidence of toenail fungus is up to 20 % of the population. Trichophyton rubrum is the most common microorganism in cases of fungal toenail infections. The pathogen is commonly found in public places associated with humid conditions. Such places as public showers, gyms, locker rooms, and pools have a higher incidence of these microorganisms. Fungal infections flourish in warm dark humid environments such as the inside of shoes and boots. Risk factors include diabetes, circulatory or immune system problems as well as excessive sweating. People who have frequent athlete’s foot skin infections are more susceptible to toenail fungal infections.

Athlete's foot ( Tinea pedis) is a skin infection caused by a dermatophyte (a pathogenic fungus that grows on the skin). Sometimes it is referred to as Ringworm because it can cause a red itchy circular rash. It can be found anywhere on the foot, as well as between the toes. Dermatophytes can also attack the toenails also known as Onychomycosis. People who have frequent athlete’s foot skin infections are more susceptible to toenail fungal infections.
