Which of the following is a sign of fungal infection in the nails?

A fungal infection in the nails can manifest in various ways, and the symptoms listed are all indicative of such infections.

Peeling nails may occur as the fungal infection disrupts the normal integrity of the nail structure, leading to the layers of the nail becoming compromised and separating.

White, scaly patches are another common sign of a fungal infection, as it can cause discoloration and changes in the texture of the nail surface.

The separation of the nail from the nail bed, known as onycholysis, is a significant indicator of a fungal infection, as the pathogen can affect the attachment of the nail to the underlying skin, leading to detachment.

Each of these symptoms highlights how a fungal infection can affect nails in different ways, emphasizing the importance of recognizing multiple signs to diagnose the condition accurately. Therefore, identifying that all mentioned signs can point to a fungal infection makes this selection the most comprehensive answer.
