HA-MRSA is spread primarily by

• A. Direct physical contact with an infected person
• B. Airborne transmission via coughing
• C. Contaminated food handling
• D. Bloodborne exposure

Answer: (A)

Direct contact with an infected person is the main way HA-MRSA spreads. The bacteria live on skin and in the nose and can transfer when someone touches an infected wound or drainage and then touches their own skin or mucous membranes, or when they touch contaminated surfaces or medical equipment and then touch themselves. In hospital settings, healthcare workers’ hands are the primary vehicle for transmission, which is why diligent hand hygiene, gloves, gowns, and proper cleaning of equipment and surfaces are essential. It isn’t spread primarily through the air, through contaminated food handling, or via blood exposure.
