While it is not possible to eradicate all of the MRSA-causing bacteria in any environment, there are steps that people can take to cut down on the likelihood of re-infection, according to the Minnesota Department of Health. An active MRSA infection is typically healed in about 10 days, but many people are colonized with the MRSA bacteria, making subsequent outbreaks possible, according to the MRSA Research Center.
Methicillin-resistant Staphylococcusaureus bacteria causes various skin infections as well as more serious internal infections and can live in the nose and on the skin of a carrier until a break in the skin allows it to enter, as stated by the Minnesota Department of Health. If someone in a household has recurrent MRSA infections, once the active infection is relieved through draining and the use of antibiotics, the Minnesota Department of Health advises the person to wash with antibacterial soap, use an antibacterial ointment in the nose and, in some case, take additional antibiotics to cut down on the bacterial load on the skin. This source also advises that always keeping wounds covered, bathing often, wearing clean clothes, changing sheets frequently and avoiding contact sports until sores are healed helps prevent the spread of MRSA to others.
