Wound infections

A wound is damaged or breaks in the surface of the skin. The wound is divided into two types, they are acute wound that includes minor cuts, laceration, bites, etc, and chronic wounds that can become slow to heal including ulcers on the legs and feet. Redness, pain, and swelling are signs of a wound.
