A MRSA carrier is a person who has MRSA bacteria on the skin or in the nose without having any symptoms of infection, explains the Minnesota Department of Health. An example of a carrier is someone who has MRSA on her skin but does not have sores, boils or other symptoms.
Methicillin-resistant Staphylococcus aureus, abbreviated MRSA, is a type of bacteria resistant to common antibiotics, as defined by the Minnesota Department of Health. Staph bacteria are usually found in the nose and on the skin, but they don't cause problems unless they get inside the body. It is possible to contract MRSA by touching an infected person, touching surfaces that have MRSA bacteria on them or sharing personal items with someone who has the infection.
People who frequently take antibiotics have a higher risk of contracting MRSA infections, notes the Minnesota Department of Health. MRSA infection is also more likely in people who do not follow the dosing instructions on antibiotics, people who sustain frequent scrapes or cuts, and people who take antibiotics without getting a prescription from a doctor. Skin infections are one of the most common problems caused by MRSA. Symptoms of MRSA-related skin infections include boils, sores, pus-filled blisters and painful bumps under the skin.
