White nail fungus

Nail fungus is caused by a variety of fungi that invade the nail bed and the underside of the nail plate. It then moves toward the base of the nail, which can thicken and become discoloured. This type of infection is associated with a compromised immune system, especially human immunodeficiency virus (HIV).

It is important to seek treatment for nail fungus as the infection can spread to other nails and affect the way your toe and nails look. Fungal infections are common and easy to treat and prevent.

Yellow nail fungus

Nail fungus occurs when a fungus attacks a fingernail, toenail, or the skin under the nail, known as the nail bed. The fungus often starts as a white or yellow spot under the nail, which can spread and turn the whole nail white, yellow, green, or black. The nail may thicken and become hard to trim, and it may start to curl up or down or loosen from the nail bed. This is associated with a compromised immune system, especially human immunodeficiency virus (HIV).

The fungus is typically caused by Trichophyton rubrum, which invades the nail bed and the underside of the nail plate before moving towards the base of the nail. This area then thickens and becomes discoloured.

To prevent and treat yellow nail fungus, it is important to maintain good nail hygiene and seek timely medical attention.
