What type of infection is described by the term Onychia?

Onychia refers to an infection that affects the nail matrix and can be caused by bacteria or fungi. This condition is characterized by redness, inflammation, and in some cases, pus formation around the affected nail. The term encompasses both types of infections because both bacteria (such as staphylococci) and fungi (like dermatophytes) can invade the nail area, leading to similar symptoms. Recognizing this allows for appropriate treatment measures to be taken, which might include the use of antifungal or antibacterial medications, depending on the underlying cause of the infection.

Viral and parasitic infections are not typically associated with onychia, as these would result in different types of issues not specifically described by this term. Additionally, while chronic conditions may develop as a result of recurrent infections, onychia itself is not defined as chronic; the term focuses specifically on the infectious aspect.
