wound infection

A wound infection occurs when harmful bacteria or germs enter a break in the skin, such as a cut or surgical incision, and multiply there. This can cause redness, swelling, pain, warmth, and sometimes pus or bad odor. Infections may slow healing and, if untreated, can spread to other parts of the body or cause serious health problems. Proper wound care, keeping the area clean, and seeking medical attention if symptoms develop are important to prevent and treat infections effectively.
