What is a paronychia?

A paronychia refers to an infection that occurs around the nail fold, which is the area of skin that borders the sides and base of the nail. This condition can develop due to various factors, including trauma to the nail area, exposure to irritants, or the introduction of bacteria or fungi through breaks in the skin. The symptoms often include redness, swelling, and pain in the affected area, and sometimes pus formation.

Understanding paronychia is vital for nail technicians, as it helps them recognize signs of infection and advise clients on proper nail care to prevent such conditions. While other options may relate to nail health, they describe different issues — such as allergies, fungal infections, or cosmetic effects, which do not specifically characterize the infection around the nail fold that is central to a paronychia.
