These are much less common than skin infections.

Treatment for staph infections

Staph infections usually get better on their own, but you may need treatment from a GP if your symptoms do not get better after a week. You may need: antibiotic tablets, creams or eye drops a small procedure to have any boils, carbuncles or abscesses drained and cleaned a stye removed by a GP Some people may be referred to a specialist if treatment from a GP does not help.

How staph infections are spread

The bacteria that cause staph infections live harmlessly on many people's skin, often in the nose and armpits and on the buttocks. They usually only cause an infection if they get into the skin, such as through a bite or cut. Staph bacteria can spread to others through: close skin contact sharing things like towels or toothbrushes droplets in coughs and sneezes (but this is less common)

Preventing staph infections

It can be difficult to prevent staph infections because many people have the bacteria on their skin. But there are things you can do to lower your chances of getting an infection or spreading the bacteria to others. Do wash your hands with soap and water regularly keep your skin clean by having a bath or shower every day keep any cuts clean and covered use disposable tissues to blow your nose Don’t do not share towels, washcloths, bed linen, toothbrushes or razors
