Toenail fungus, also known as onychomycosis, is a type of fungal infection that impacts the nails, including those on the toes. It is primarily caused by different types of fungi called dermatophytes, but other types of fungi such as yeasts and molds can also be responsible. These types of fungi thrive in warm and damp conditions. https://podiatryabc.com/o-is-for-onychomycosis/
