Wound fever, also known as surgical site infection (SSI), can have several synonyms. These include postoperative infection, incisional infection, or surgical wound infection. These infections occur when bacteria infect the surgical wound or incision site causing inflammation, redness, and sometimes fever. The severity of the infection can range from mild to life-threatening. Treatment may involve antibiotics, wound drainage, or surgery to remove infected tissue. Preventative measures such as proper wound care, sterile technique during surgery, and appropriate antibiotic prophylaxis can reduce the risk of wound fever or SSI. It is important to seek medical attention promptly if symptoms of an infection occur after surgery.
