A surgical site infection (SSI) is an infection that occurs after surgery. SSIs can occur at any time, from immediately after surgery up to one year later. Most SSIs occur within the first 30 days after surgery.
The main types of bacteria that cause SSIs are:

SSIs can lead to serious complications, including sepsis and death. The best way to prevent SSIs is for patients to practice good hygiene before and after surgery.
