How was MRSA transmitted in the case of the technologist who developed an infectious lesion?

The transmission of Methicillin-resistant Staphylococcus aureus (MRSA) in the case of the technologist who developed an infectious lesion is most commonly associated with direct contact. MRSA is primarily spread through contact with infected wounds or personal items, such as towels or razors, that have been contaminated with the bacteria. This type of transmission suggests that the technologist likely had direct skin-to-skin contact with an infected person or contaminated object, leading to the development of an infectious lesion.

In contrast, the other modes of transmission listed—airborne particles, contaminated surfaces, and vector-borne—are not the primary routes for MRSA. Airborne transmission typically involves pathogens that can remain suspended in the air, contaminated surfaces may contribute to indirect transmission, but direct contact remains the most significant and common pathway for MRSA infections in healthcare settings. Vector-borne transmission involves organisms carried by insects, which is not applicable in the case of MRSA. Thus, direct contact best explains the transmission scenario for the technologist’s infection.
