A community gathering in Ireland's Dublin and Midlands region in autumn 2025 became the site of a significant public health incident when 48 children contracted a hypervirulent, multidrug-resistant strain of MRSA following exposure to a bouncy castle. The event, which drew approximately 120 attendees including some 60 children and teenagers, has been identified as the source of what medical authorities describe as the largest recorded MRSA outbreak in Ireland.

The outbreak marks a previously undocumented transmission pathway for MRSA infection, with public health experts noting the unusual connection between the recreational equipment and disease spread. Research on the incident, published in the journal Eurosurveillance, underscores how surface contamination and prolonged close contact during routine children's party activities can facilitate rapid propagation of serious pathogens, raising broader questions about infection control in shared recreational spaces.
