Methicillin-resistant Staphylococcus aureus (MRSA) Guidance for nursing staff MRSA – key facts MRSA (methicillin-resistant Staphylococcus aureus) is a strain of Staphylococcus aureus which is resistant to methicillin and other antibiotics. So far, 16 epidemic strains of MRSA have been discovered but two particular strains (clones 15 and 16) are thought to be more transmissible than the others. Staphylococcus aureus is an organism that colonises the skin, particularly the nose, skin folds, hairline, perineum and navel. It commonly survives in these areas without causing infection – a state known as colonisation. A patient becomes clinically infected if the organism invades the skin or deeper tissues and multiplies. MRSA is prevalent in health care environments because individuals tend to be older, sicker and weaker than the general population, which heightens their vulnerability to infection through weakened immunity. In addition, these environments involve a great many people living and working together closely – perfect for transferring MRSA. The symptoms of a person with MRSA vary depending on what part of the body is infected. Common symptoms include redness, swelling and tenderness at the site of infection. Sometimes, people may carry MRSA without having any symptoms. In order to reduce the spread of MRSA health care staff should ensure that they wash their hands thoroughly between patients.
