Cellulitis Causes, Symptoms & Treatments

Cause #3: Cuts, Scratches, Wounds
As one of our primary defense systems is the skin, a break in the skin caused by a cut or scratch allows bacteria to invade. Once bacteria invade the deeper layers of the skin, it colonizes the area and multiplies causing damage to the area. If the wound becomes infected, it can be a great breeding ground for bacteria. This is the reason why any wound should be sanitized or cleaned to lower the risk of infection.
Most cases are minor, and the infection is localized to the area and only the skin. However, in severe cases, the invasion of the bacteria into the blood stream can cause joints, bones, and organs such as the heart and brain to be involved, leading to life-threatening situations.
