Bouncy Castle Linked to Largest MRSA Outbreak in Ireland
Confirmed
In Short: A rare strain of MRSA, linked to bouncy castles, caused the largest outbreak ever recorded in Ireland, affecting four children who required hospitalization.
The results of an outbreak investigation, reported in the journal Eurosurveillance, revealed that a unique strain of MRSA, capable of producing a cytotoxin, was responsible for the largest MRSA outbreak in Ireland's history, linked to bouncy castles.
This strain, t016-ST22-MRSA-IV, showed resistance to at least four drugs, including flucloxacillin, ciprofloxacin, gentamicin, and trimethoprim, making it particularly concerning for public health officials.
The outbreak, which began at a community event with three bouncy castles, affected four children, leading to hospitalizations. The first case was a 12-year-old boy who was diagnosed with MRSA folliculitis and required hospital treatment.
Local health officials became aware of the outbreak nine days after the event when a 12-year-old boy was hospitalized for a skin infection. An outbreak control team was convened when 25 other children who had attended the same event sought treatment with unusual skin infections.
Dr. McGlacken-Byrne, from the HSE’s Department of Public Health, noted that this strain of MRSA had not previously been linked to an outbreak in either a healthcare setting or in the community in Ireland, highlighting the unusual nature of this event.
Background
Ireland is an island in the North Atlantic Ocean, in Northwestern Europe. Geopolitically, the island is divided between the Republic of Ireland and Northern Ireland.

What's still developing
- So-called community-associated MRSA is often linked to crowded settings where people have close contact, such as sports activities, daycares, and prisons.
- For a child bursting with energy, few things are more fun than hurtling through a bouncy castle, launching into the air, and ping-ponging between every surface.
- That was the horrifying reality for a community in Ireland in fall 2025.
- Neighbors had gathered for an afternoon of merriment, complete with a barbecue, a sweets station, and three bouncy castles.
- His doctors had determined he was infected with MRSA—aka methicillin-resistant Staphylococcus aureus.
- The study included nearly 1 million U.K. adults, making it the largest investigation of its kind to date, according to lead study author Keren Papier, a nutritional epidemiologist at the University of Oxford.
- A new medical report has revealed that four children were hospitalised after an outbreak of a rare and aggressive strain of methicillin-resistant Staphylococcus aureus - better known as MRSA - swept through a large group who had been playing on bouncy castles.
- While outbreaks of community-acquired MRSA are associated with close physical contact and crowded settings, most previous large outbreaks have been found in sporting activities, prisons and childcare facilities.
