在四个月的时间里，六名患者在强化治疗单位成为定植或感染耐甲氧西林金黄色葡萄球菌（MRSA）。这些患者中有4人被流行性MRSA菌株15（EMRSA 15）定殖。这次爆发的特点是，所有这四名患者在获得该生物体之前都在该单位的同一张床上接受护理。对爆发的调查使作者相信MRSA的来源可能是相邻隔离室通风系统的排气管道，该通风系统允许微生物通过位于该特定床上方的部分打开的窗户进入该单元。一旦通风系统被修复，床上方的窗户被正确密封，这个循环就被打破了。
During a four-month period, six patients on an intensive therapy unit became colonized or infected with methicillin-resistant Staphylococcus aureus (MRSA). Four of these patients were colonized by the Epidemic MRSA strain 15 (EMRSA 15). The outbreak was characterized by the fact that all four of these patients were nursed in the same bed on the unit before acquisition of the organism. Investigation of the outbreak led the authors to believe that the source of the MRSA may have been the exhaust ducting of the adjacent isolation room ventilation system which allowed the organisms to enter the unit via a partially open window positioned above that particular bed. The cycle was broken once the ventilation system was repaired and the window above the bed was properly sealed.
