What are the signs of a fungal infection on nails?

1. Rough texture

2. Discoloration and separation

3. Smell and pain

4. None of the above

The correct answer is: Discoloration and separation

Discoloration and separation of the nails are classic signs of a fungal infection. When a fungal infection occurs, it often leads to changes in the color of the nails, which can appear yellow, white, or brown. This discoloration is typically due to the buildup of debris and fungal elements beneath the nail. Additionally, as the infection progresses, the infected nail may begin to separate from the nail bed, a condition known as onycholysis. This separation can create a gap that allows more fungi to populate, worsening the infection. The combination of these symptoms—discoloration and the physical separation of the nail—provides strong indicators that a fungal infection is present. While rough texture, smell, and pain are associated with various nail conditions, they are not definitive signs of a fungal infection specifically. Rough texture could be influenced by other factors, and while a fungal infection may produce an odor or lead to some discomfort, these symptoms are less indicative compared to the clear signs of discoloration and nail separation.
