What are skin infections?
Your skin is your body's largest organ. It has many different functions,
including covering and protecting your body. It helps keep germs out. But
sometimes the germs can cause a skin infection. This often happens when there
is a break, cut, or wound on your skin. It can also happen when your immune
system is weakened, because of another disease or a medical treatment.
Some skin infections cover a small area on the top of your skin. Other infections
can go deep into your skin or spread to a larger area.
