确定性Kermack-McKendrick模型是一般随机流行病的边界

The deterministic Kermack-McKendrick model bounds the general stochastic epidemic

Robert R. Wilkinson, Frank G. Ball, Kieran J. Sharkey

摘要:

我们证明了,对于泊松传播和恢复过程,经典的易感$\to$感染$\to$感染(SIR)的流行病模型的Kermack和McKendrick提供了,对于任何给定的时间$t>0$,一个严格的下限的预期数量的易感和严格的上限的预期数量的恢复一般随机SIR流行病。证明是基于最近的消息传递表示SIR流行病应用到一个完整的图。

英文摘要:

We prove that, for Poisson transmission and recovery processes, the classic Susceptible $\to$ Infected $\to$ Recovered (SIR) epidemic model of Kermack and McKendrick provides, for any given time $t>0$, a strict lower bound on the expected number of suscpetibles and a strict upper bound on the expected number of recoveries in the general stochastic SIR epidemic. The proof is based on the recent message passing representation of SIR epidemics applied to a complete graph.
