MRSA bacteria spread to others via contact with a MRSA skin infection, a person or pet harboring MRSA bacteria, or objects contaminated with MRSA bacteria.
MRSA bacteria are subsequently transferred to other parts of the body, whereby they can directly infect a wound, broken skin, or the exposed individual can become a carrier.
Note: MRSA bacteria are not typically airborne, and coughing does not spread MRSA unless someone has MRSA pneumonia.
