Is paronychia contagious?

Paronychia is usually not contagious.

Paronychia is mainly caused by damage to the nail groove and surrounding tissues, infection, etc., rather than direct transmission of pathogens. For example, improper nail trimming, minor skin trauma near the nail groove, long-term contact with irritants, etc., may induce paronychia, which is usually unrelated to infection.

Although paronychia itself is not infectious, if it is caused by a special type of infection such as fungi, there may be a certain risk of infection. However, this infection is not as easy to occur as some infectious diseases, but under certain circumstances, such as close contact, sharing items, etc., there may be transmission.
