What is a nail fungus?
​
Nail fungus, also known as onychomycosis, is a fungal infection that affects the nails of the feet or hands. It can cause the nail to become thick, discolored, and brittle. In severe cases, the infected nail may separate from the nail bed. Nail fungus is a common condition and can be caused by various types of fungi, including dermatophytes, yeasts, and molds. It is often spread in warm, moist environments such as public showers, swimming pools, and gym floors. Nail fungus can be difficult to treat and may require antifungal medication taken orally or applied topically. In severe cases, surgery to remove the infected nail may be necessary. Good hygiene practices, such as keeping the feet and hands clean and dry, can help prevent the spread of nail fungus.
