疾病传播问题的研究,一直是科学家所关注的焦点。近几年兴起研究的复杂网络,真实地反映出现实中系统的某些重要特性,成为研究现实网络的有效手段。在介绍复杂网络的基础上,着重阐述了复杂网络描述疾病传播的研究工作及成果,特别指出其应用于SARS病毒传播研究得到的一些有意义的结论,从而为控制病毒的传播提供了一种重要的参考依据。

The problem of epidemic spreading has always been concerned by many scientists. Recently, complex networks that properly reflect some important features in actual system become an effective method to research real networks.. Concept of complex networks is introduced, the research work and results of epidemic spreading in complex networks are expounded. In particular, the application of complex networks to SARS spreading research was pointed out. Some significant conclusions were found, which provides an important guide for epidemic control
