What is a potential cause of paronychia?

Paronychia is an infection of the tissue around the nails, typically presenting with redness, swelling, and pain. The correct answer indicates that a range of factors can contribute to the development of this condition, highlighting the multifactorial nature of paronychia.

Excessive dryness can lead to cracks and fissures in the skin surrounding the nails, creating an entry point for pathogens. When the skin barrier is compromised, the risk of developing infections such as paronychia increases.

Frequent hand washing, while important for hygiene, can lead to skin irritation and dryness. This continuous exposure to water and soaps can strip the skin of its natural oils, again making it more susceptible to infections.

Mechanical injury, such as biting or picking at the skin around the nails, can also facilitate the entry of bacteria or fungi, leading to paronychia. In addition, injuries can cause inflammation, which further increases the risk of infection.

The inclusion of all these potential causes underscores the complexity of how paronychia can arise, making "All of the above" the most comprehensive and correct choice.
