摘要翻译：
然而，尽管医院治疗取得了进展，医院仍然是几种空气传播疾病和通过密切接触者传播的疾病的滋生地，如非典、耐甲氧西林金黄色葡萄球菌(MRSA)、诺如病毒感染和结核病。在这里，我们从一个用于管理服务于190万人口的当地公共医疗保健系统的数据库中提取了多达295,108名住院患者长达两年的联系网络。运用网络流行病学的方法，分析了传染病传播的重要网络的结构和动力学性质。接触网络在很大程度上取决于住院时间和医院结构的极端（与年龄无关）变化。我们发现住院病人之间的接触结构表现出高度的传递性、多样性和接触次数的变异等结构特征，这些特征可能对传染性较低的疾病的传播具有重要意义。如果在设计预防方案时考虑到这些特性，就可以降低流行病爆发的风险和影响。

英文摘要：
  Yet in spite of advances in hospital treatment, hospitals continue to be a breeding ground for several airborne diseases and for diseases that are transmitted through close contacts like SARS, methicillin-resistant Staphylococcus aureus (MRSA), norovirus infections and tuberculosis (TB). Here we extract contact networks for up to 295,108 inpatients for durations up to two years from a database used for administrating a local public healthcare system serving a population of 1.9 million individuals. Structural and dynamical properties of the network of importance for the transmission of contagious diseases are then analyzed by methods from network epidemiology. The contact networks are found to be very much determined by an extreme (age independent) variation in duration of hospital stays and the hospital structure. We find that that the structure of contacts between in-patients exhibit structural properties, such as a high level of transitivity, assortativity and variation in number of contacts, that are likely to be of importance for the transmission of less contagious diseases. If these properties are considered when designing prevention programs the risk for and the effect of epidemic outbreaks may be decreased.
