Hospital care — Risk factors for becoming infected with hospital-associated MRSA include the following:●Having a surgical wound and/or intravenous (IV) line●Being hospitalized for a prolonged period of time●Recent use of antibiotics●Having a weakened immune system due to a medical condition or its treatment●Being in close proximity to other patients or healthcare workers who are colonized with MRSA

The skin may have a single raised red lump that is tender, a cluster of "pimples", or a large tender lump that drains pus (called a carbuncle). The area may enlarge and become progressively more tender, red, and swollen. The center of the raised area may ooze pus.

People with infections of the lung, bone, joint, or other internal areas usually require blood tests as well as imaging studies (eg, x-ray, computed tomography [CT] scan, echocardiogram).

Prevention in the hospital — In the hospital, MRSA is commonly spread to patients from the hands of healthcare workers. To minimize this risk, patients and family members can help to ensure that anyone who comes in contact with the patient washes their hands or uses an alcohol-based hand sanitizer before and after touching the patient. Patients with active infection should also wash their hands frequently.

Prevention in the community — The best way to prevent and control MRSA in the community is not clear. The United States Centers for Disease Control and Prevention has made the following recommendations [4]:●Keep hands clean by washing thoroughly with soap and water. Hands should be wet with water and plain soap and be rubbed together for 15 to 30 seconds. Special attention should be paid to the fingernails, between the fingers, and the wrists. Hands should be rinsed thoroughly and dried with a single-use towel (eg, paper towels).●Alcohol-based hand sanitizers are a good alternative for disinfecting hands if a sink is not available. Hand sanitizers should be rubbed over the entire surface of hands, fingers, and wrists until dry and may be used several times. Hand sanitizers are available as a liquid or wipe in small, portable sizes that are easy to carry in a pocket or handbag. When a sink is available, visibly soiled hands should be washed with soap and water.●Keep cuts and scrapes clean, dry, and covered with a bandage until healed.●Avoid touching other people's wounds or bandages.●Avoid sharing personal items such as towels, washcloths, razors, clothing, or uniforms. Other items that should not be shared include brushes, combs, and makeup.●Students who participate in team sports should shower after every athletic activity using soap and clean towels. Athletes with skin infections should receive prompt treatment and should not compete when they have draining or active skin infections.●People who use exercise machines at sports clubs or schools should be sure to wipe down the equipment, including the hand grips, with an alcohol-based solution after using it.

“MRSA has become so widespread in the community, that it’s become nearly impossible to predict which patients harbor MRSA on their body,”
