The incidence rate for invasive and noninvasive Staphylococcus aureus infections in New Zealand is among the highest reported in the developed world. Using nationally collated hospital discharge data, we analyzed the epidemiology of serious S. aureus infections in New Zealand during 2000-2011. During this period, incidence of S. aureus skin and soft tissue infections increased significantly while incidence of staphylococcal sepsis and pneumonia remained stable. We observed marked ethnic and sociodemographic inequality across all S. aureus infections; incidence rates for all forms of S. aureus infections were highest among Māori and Pacific Peoples and among patients residing in areas of high socioeconomic deprivation. The increased incidence of S. aureus skin and soft tissue infections, coupled with the demographic disparities, is of considerable concern. Future work should aim to reduce this disturbing national trend.
新西兰侵袭性和非侵袭性金黄色葡萄球菌感染的发病率在发达国家中位居前列。利用全国收集的医院出院数据，我们分析了2000年至2011年期间新西兰严重金黄色葡萄球菌感染的流行病学情况。在此期间，金黄色葡萄球菌皮肤和软组织感染的发病率显著上升，而葡萄球菌败血症和肺炎的发病率保持稳定。我们观察到在所有金黄色葡萄球菌感染中存在明显的种族和社会人口统计学不平等现象；所有形式的金黄色葡萄球菌感染发病率在毛利人和太平洋岛民以及居住在社会经济高度贫困地区的患者中最高。金黄色葡萄球菌皮肤和软组织感染发病率的上升，再加上人口统计学上的差异，令人深感担忧。未来的工作应致力于减少这一令人不安的全国性趋势。
