MRSA stands for 'Methicillin-Resistant Staphylococcus Aureus .  Methicillin is an  antibiotic commonly used to treat staphylococcus infections. Staphylococcus Aureus  often referred to simply as  "staph," is a bacteria commonly found on the skin of healthy people. It is also found in the nose and urine. It can be present in the body without causing infection or illness. The type of infections that  staph can cause  range from skin conditions such as pimples and boils to infections which can be serious such as blood infections or pneumonia . The Doctor may prescribe Methicillin antibiotics which are very effective in treating most staph infections. But because some staph bacteria  have developed resistance to methicillin , hence the name MRSA , they will not be  killed by  this antibiotic.
MRSA is resistant to many antibiotics but there are a few which are successful . If you are not infected but are a carrier of MRSA you would not normally need any treatment.
Healthy people rarely get MRSA .It is more commonly picked up in hospital by patients, who are often very sick with weak  immune systems that may not be able to fight off infections. Patients with open wounds such as pressure sores or leg ulcers or have a urinary catheter inserted are also susceptible to an MRSA infection.
MRSA is always spread by physical contact, and not through the air. In hospitals to prevent the spread of MRSA the  patient with MRSA is isolated in a private room . Staff and  visitors  wear  gloves  and gowns, as they are  likely , intentionally or unintentionally , to come in contact with  the patient's skin, blood, urine, wound, or other body substances. To avoid carrying  MRSA out of the room with them , staff and visitors should always wash their hands before leaving . Healthy  family members or other visitors can be  in the same room with a person with MRSA and casual contact, such as touching  or  hugging, is usually allowed . However, they must wash their hands before leaving the hospital room (or the patient's home). The patient may be isolated for a few weeks in  the hospital or their home
You must always seek your Doctors or Community Nurses advice. In general terms though your carers should always wash their hands, wear gloves or gowns when coming into contact with bodily substances. Periodic cleaning of your room and personal items with a  disinfectant is advised . You yourself should follow good hygiene practices and tell visitors that you have MRSA . Healthy people including children are at very little risk while visiting   providing they limit physical contact and wash their hands afterwards. Finally visitors who are ill or have a weak immune system should avoid physical contact.
