随机性和空间异质性是近年来研究传染病传播的重要内容。该方法解决了一个反问题,以有效地发现异构网络的决定性拓扑结构,并从传染病爆发的早期生长阶段的数据集中揭示控制网络随机传播的传播参数。用随机微分方程描述了流行病学分室模型和元种群网络模型组合中的种群。由方程导出概率密度函数,用于拓扑结构和参数的极大似然估计。用计算合成数据集和SARS爆发的世界卫生组织数据集对该方法进行了检验。

英文摘要:
  Stochasticity and spatial heterogeneity are of great interest recently in studying the spread of an infectious disease. The presented method solves an inverse problem to discover the effectively decisive topology of a heterogeneous network and reveal the transmission parameters which govern the stochastic spreads over the network from a dataset on an infectious disease outbreak in the early growth phase. Populations in a combination of epidemiological compartment models and a meta-population network model are described by stochastic differential equations. Probability density functions are derived from the equations and used for the maximal likelihood estimation of the topology and parameters. The method is tested with computationally synthesized datasets and the WHO dataset on SARS outbreak.
