What are the signs of wound infection?

The signs of wound infection are characterized by increased redness, swelling, pus, fever, and delayed healing. When a wound becomes infected, it typically exhibits inflammation, which manifests as redness and swelling due to increased blood flow and immune response to the infection. The presence of pus indicates the accumulation of dead white blood cells, bacteria, and tissue debris at the infection site.

Fever is a systemic response that can occur when the body's immune system is combating an infection, as it raises body temperature to create an environment less favorable for bacteria. Delayed healing is another indicator, as an infection can prevent normal healing processes, prolonging recovery time. Together, these signs help healthcare providers identify and address wound infections promptly, ensuring proper treatment and management.
