The bacteria that cause staph infections live harmlessly on many people’s skin, usually in the nose and armpits and on the buttocks.
They usually only cause an infection if they get into the skin – for example, through a bite or cut.
The infection usually clears up on it’s own without the need for antibiotics.
But in some cases staph bacteria can also cause more serious infections, like blood poisoning and toxic shock syndrome.
