Which type of infection results from a procedure or treatment?

Surgical site infections are specifically associated with procedures or treatments, typically occurring in the area where surgery has taken place. These infections can arise from bacteria entering the body through the incision made during the surgical procedure. They are a significant concern in medical settings because they can lead to complications, prolong hospital stays, and increase healthcare costs.

The other types of infections mentioned do not necessarily stem from procedures or treatments. Viral infections can occur from various sources such as exposure to infected individuals or surfaces, rather than being linked to a specific treatment. Mild infections refer to less severe cases that can arise from numerous causes, and chronic infections are those that persist over a long term, generally not tied to a specific event or procedure. This highlights why surgical site infections are the relevant category for infections resulting from a treatment or procedure.
