Symptoms of a staph skin infection can include:

• a painful red lump or bump (a boil, carbuncle or abscess)
• hot, red and swollen skin (cellulitis)
• sores, crusts or blisters (impetigo)
• sore, red eyelids or eyes (styes or conjunctivitis)

Redness affecting the skin or eyelids may be harder to see on brown or black skin.

Staph bacteria can also cause more serious infections, like blood poisoning and toxic shock syndrome. These are much less common than skin infections.

Ask for an urgent GP appointment or call NHS 111 if:

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.

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)

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.
