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.
在四个月的时间里，重症监护病房的六名患者被耐甲氧西林金黄色葡萄球菌（MRSA）定植或感染。其中四名患者被流行的MRSA菌株15（EMRSA 15）定植。此次暴发的特点是，这四名患者在感染该病菌之前都在该病房的同一张床上接受护理。对此次暴发的调查使作者认为，MRSA的来源可能是相邻隔离室通风系统的排气管，这些病菌通过位于那张特定病床上方的一扇半开的窗户进入了病房。一旦通风系统得到修复，病床上方的窗户得到妥善密封，这个循环就被打破了。
