What caused MRSA outbreak at bouncy castle Ireland?

The MRSA outbreak, described as Ireland's largest on record, was linked to children playing on bouncy castles at a community gathering in the HSE Dublin and Midlands region last autumn. It affected 48 children and adolescents with skin and soft tissue infections, 15 of whom needed hospital treatment, and the strain involved was reported as hypervirulent and multidrug-resistant [1, 2]. Doctors have described the bouncy castle as a previously undocumented route for spreading the infection, though the exact mechanism by which it harboured or transmitted the bacteria isn't detailed in the coverage provided [2, 3].
