A multiclonal methicillin-resistant Staphylococcus aureus (MRSA) outbreak with 91 infections occurred in our Veterans Affairs (VA) community living center over 46 months. Both similar and unique strains were shown by repetitive polymerase chain reaction to contribute to the outbreak, including 1 strain causing infections over a 33-month period. Most infections were soft tissue infections (67%). For 21 months after the initiation of the VA MRSA bundle, no infections were identified, and low rates of infection have been sustained an additional 4 years. The average annual rate of MRSA infection decreased by 62% (P < .001) from 0.6 per 1,000 resident days for 4 years prior to the bundle implementation to 0.09 per 1,000 resident days for 4 years after the bundle implementation.
在46个月的时间里，我们退伍军人事务部（VA）社区生活中心发生了一起多重克隆耐甲氧西林金黄色葡萄球菌（MRSA）暴发，共有91例感染病例。重复聚合酶链反应显示，相似和独特的菌株都导致了此次暴发，其中1株在33个月内引发了感染。大多数感染为软组织感染（67%）。在启动VA MRSA综合防控措施后的21个月里，未发现感染病例，且低感染率持续了另外4年。MRSA感染的年均发生率从实施综合防控措施前4年的每1000个住院日0.6例下降了62%（P < 0.001），至实施综合防控措施后4年的每1000个住院日0.09例。
