Bouncy Castle Outbreak Infects 48 Children with MRSA in Ireland

MRSA Outbreak at Community Event

In fall 2025, a community gathering in Ireland, featuring a barbecue and bouncy castles, resulted in 48 children developing aggressive skin and soft-tissue infections. Approximately 120 people attended the event, with half being children and teens. Symptoms began appearing within a day for some children.

Infection Details and Treatment

Of the 48 cases, 33 were treated by general practitioners, and 15 sought emergency care. Four children were hospitalized due to the severity of their infections. All affected children eventually recovered. The findings of the outbreak investigation were published in the journal Eurosurveillance.

Discovery and Pathogen Identification

Local health officials were alerted nine days post-event when a 12-year-old boy was hospitalized with a MRSA skin infection. Genomic sequencing identified the causative agent as a rare strain of MRSA that produces Panton–Valentine leukocidin (PVL), a cytotoxin known to destroy immune cells and cause inflammation, often associated with necrotic lesions.

Rapid Symptom Onset

The MRSA strain demonstrated rapid progression, with most infected children developing symptoms within four days of exposure, significantly faster than the typical 4–10 day incubation period. Some experienced symptoms within hours. Common symptoms included spots, pustules, blisters, and abscesses, primarily on the legs, consistent with bouncy castle contact. Twelve children also reported systemic symptoms like fever, nausea, or vomiting.
