病毒变异在小世界网络中的传播
首发时间:2005-01-11
摘要:我们研究了一种病毒变异传播模型在小世界网络中的动态行为,讨论了免疫时间$\tau_{R}$,交叉免疫阈值$h_{thr}$和系统大小$N$对传播动力学的影响。由于免疫和病毒变异的相互作用,出现了一种振荡衰减行为。这些结果能用于解释疾病长时间传播和病毒的多样性,还能帮助评估蓄意投放可变异病毒带来的危险性。

Epidemics with Pathogen Mutation on Small-World Networks
Abstract:We study the dynamical behavior of the epidemiological model with pathogen mutation on small-world networks, and discuss the influence of the immunity duration $\tau_{R}$, the cross-immunity threshold $h_{thr}$, and system size $N$ on epidemic dynamics. A decaying oscillation occurs because of the interplay between the immune response and the pathogen mutation. These results have implications for the interpretation of longitudinal epidemiological data on strain abundance, and they will be helpful to assess the threat posed by deliberate release of mutable virus.
