Staph infection

What is a staph infection?

Staph infection is short for staphylococcal infections, and these can cause symptoms ranging from impetigo and cellulitis of the skin, to septicaemia blood infection and endocarditis affecting the lining of the heart.

The staph bacteria lives harmlessly on the skin or in the noses of many people, but infections can occur after getting a cut or wound.

MRSA is a staph infection that can be picked up in hospital, and is dangerous because it is resistant to treatment with many antibiotics.

People with conditions like diabetes or those with weakened immune systems are more at risk of staph infections.

What are the symptoms of staph Infection?

Staph cellulitis usually begins as a small area of tenderness, swelling and redness. Sometimes it begins with an open sore. Other times, there is no break in the skin at all and it's anyone's guess where the bacteria came from.

The signs of cellulitis are those of any inflammation: redness, warmth, swelling, and pain. Any skin sore or ulcer that has these signs may be developing cellulitis. If the staph infection spreads, the person may develop a fever, sometimes with chills and sweating, as well as swelling in the area.

What’s the treatment for staph infection?

Antibiotics are used to treat these infections but there's been a gradual change in how well these antibiotics work. While most staph infections used to be treatable with penicillin, that changed in the 1980s and different antibiotics are now used. In about 50% of cases, however, resistance is being seen to even these antibiotics. This is not just happening in hospitals, as once was the case, but is now being seen in the general community.

Another treatment is sometimes used for staph infections; if the infection goes so deep that it involves muscles, or the fibres that enclose muscles, it will need to be surgically cleaned.

Can staph infection be prevented?

You can take steps to help prevent staph infection. Any time you have a cut or break in the skin, wash it with soap and water, keep it clean and dry, use antiseptic ointment and keep it covered.

The staph infection is contagious if the wound is weeping or draining, and if people share towels or other items that are contaminated. Wearing foot coverings in changing rooms and other commonly used areas can help prevent contamination.

If the sore becomes unusually painful or red, get prompt medical attention. If red lines develop, that's a sign that the infection is spreading and needs immediate medical attention.
