how contagious is mrsa

MRSA (Methicillin-resistant Staphylococcus aureus) is quite contagious. It spreads primarily through direct skin-to-skin contact with an infected person or by touching surfaces or objects contaminated with the bacteria. MRSA can be carried on the skin or in the nose of about 2% of people, often without causing symptoms, but carriers can still spread it to others unknowingly. The bacteria can survive on surfaces for weeks to months if not disinfected. MRSA is particularly contagious when there is a break or damage in the skin, such as cuts or abrasions, which allows the bacteria to enter and cause infection. The contagious period lasts as long as the bacteria are present on or in a person's body, which can sometimes be indefinite if colonized without symptoms, or longer if there is an active infection. The infection is especially common and more easily spread in healthcare settings, but can also spread in community environments where close contact occurs, such as schools or gyms. Good hygiene, wound care, and avoiding sharing personal items are key to preventing spread.
