A MRSA carrier is someone who is not suffering from an active MRSA infection but still has the MRSA bacteria living on the skin or in the nose, according to the Minnesota Department of Health. A MRSA carrier is said to be "colonized" with the MRSA bacteria, though he has no infection and is asymptomatic.
Reducing the amount of bacteria on the skin of a MRSA carrier may help to prevent the spread of bacteria to others, according to the Minnesota Department of Health. If identified as a MRSA carrier, a doctor may recommend that a person shower using antibacterial soap for a period of time. Prescription antibacterial pills may be used, or in most cases, a prescription antibiotic ointment can be put in the nose for a number of days to lower the amount of bacteria found in the nose.
Washing hands regularly and showering using soap and water can help prevent the spread of bacteria to others, according to the Minnesota Department of Health. Wearing clean clothes, avoiding sharing personal items and covering cuts with bandages can prevent an active MRSA infection from taking place. Cleaning surfaces in the home with household cleaner can help prevent the bacteria from flourishing in the household and spreading the infection to others.
