Infectious wounds occur when bacteria or other pathogens invade a break in the skin, leading to tissue injury and delayed healing. Prompt recognition and treatment are essential to prevent complications.
Wounds can get infected if bacteria enter through a cut, bite, or surgical incision. Common causes include dirty injuries, bites, or foreign objects left in the wound. People with diabetes, weakened immunity, or poor circulation are at higher risk.
