Bouncy Castles Linked to Largest MRSA Outbreak in Ireland
Confirmed
In Short: An outbreak of a rare and aggressive strain of MRSA, linked to bouncy castles, has been identified as the largest ever recorded in Ireland, according to a study published in Eurosurveillance.
The results of the outbreak investigation were reported this week in the journal Eurosurveillance, revealing that the strain, t016-ST22-MRSA-IV, capable of producing a cytotoxin called Panton–Valentine leukocidin (PVL), was responsible for the outbreak.
Local health officials became alerted to the outbreak nine days after a 12-year-old boy was hospitalized for a skin infection, which was determined to be MRSA.
The outbreak, which involved 25 children, was linked to a community event featuring three bouncy castles, marking the first known outbreak of its kind associated with such an activity.
Dr. McGlacken-Byrne, with the HSE’s Department of Public Health, noted that the strain had not previously been linked to an outbreak in either a healthcare setting or in the community in Ireland, making it an 'unusual and complex community outbreak'.
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 confirmed
- 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.
- The first case was a 12-year-old boy who was diagnosed with MRSA folliculitis – an infection of hair follicles that causes small red pimples filled with pus – and required hospitalisation.
- The report, which is published in Eurosurveillance, a medical journal on infectious diseases, noted that an outbreak control team was urgently convened when doctors subsequently became aware of the outbreak after a cluster of 25 other children who had attended the same event sought treatment with unusual skin infections.
- Dr McGlacken-Byrne, who is with the HSE’s Department of Public Health, said the strain of MRSA in the outbreak had not previously been linked to an outbreak in either a healthcare setting or in the community in Ireland.
What's still developing
- The MRSA strain, called t016-ST22-MRSA-IV, has a unique pattern of antibiotic resistance; it could resist at least four drugs, including flucloxacillin, ciprofloxacin, gentamicin, and trimethoprim.
- 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.
- 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.
