Methicillin-resistant Staphylococcus aureus (MRSA) is emerging as a cause of skin and soft-tissue infections in persons who have little or no contact with health-care settings. The majority of these infections are mild, involving skin and soft tissue; however, certain cases can progress to invasive tissue infections, bacteremia, and death. Transmission of MRSA has been reported most frequently in certain populations (e.g., children, sports participants, or jail inmates). Persons in the American Indian or Alaska Native population in the United States and aboriginals and Pacific Islanders (PIs) in Australia have high rates of MRSA colonization and infection. In 2003, clinicians reported an increased number of skin abscesses caused by MRSA among patients examined in ambulatory care settings. This report summarizes the findings of a retrospective study of community-associated MRSA (CA-MRSA) infections in Hawaii that identified a higher proportion of cases among PIs than were identified among Asians, compared with their respective proportions in the Hawaii population. Efforts to prevent CA-MRSA in Hawaii should focus on identifying factors causing the disproportionate number of infections among PIs.
耐甲氧西林金黄色葡萄球菌（MRSA）正成为很少或几乎没有接触过医疗保健机构的人群皮肤和软组织感染的一个病因。这些感染大多数较为轻微，累及皮肤和软组织；然而，某些病例可能进展为侵袭性组织感染、菌血症甚至死亡。据报告，MRSA传播最常发生在某些人群中（如儿童、体育参与者或监狱囚犯）。美国印第安人或阿拉斯加原住民以及澳大利亚原住民和太平洋岛民（PI）中MRSA定植和感染率较高。2003年，临床医生报告称，在门诊护理机构接受检查的患者中，由MRSA引起的皮肤脓肿数量有所增加。本报告总结了一项对夏威夷社区相关MRSA（CA-MRSA）感染的回顾性研究结果，该研究发现，与夏威夷人群中各自的比例相比，PI中的病例比例高于亚洲人。夏威夷预防CA-MRSA的工作应侧重于确定导致PI中感染比例过高的因素。
