Parameters used in our SIR model to examine effects of host prior exposure on epidemiological dynamics. For all heterogeneous SIR simulations, gamma-distributed susceptibility values (first row) were used to determine the initial susceptibility distribution, while for all homogeneous SIR simulations, susceptibility values (second row) were used to determine the susceptibility of the entire population. The susceptibility for homogeneous simulations was determined from the mean of the corresponding heterogeneous models. Transmissibility and recovery rates for this system (obtained from [89]) were held constant across all groups, while other parameters were varied using model fits to empirical data. *In simulations with fixed mortality rates across groups, we used the mortality rate estimated for the no prior exposure group.

本研究用于探究宿主既往暴露对流行病学动态影响的SIR模型（SIR model）所采用的参数。在所有异质性SIR模型模拟中，我们采用伽马分布的易感性数值（第一行）来确定初始易感性分布；而在所有同质性SIR模型模拟中，则使用易感性数值（第二行）来确定整个种群的易感性水平。同质性模拟所使用的易感性数值，取自对应异质性模型的均值。本系统的传播力与恢复率（数据取自文献[89]）在所有组别中均保持恒定，其余参数则通过拟合实证数据进行调整。*在各组死亡率固定的模拟中，我们采用了无既往暴露组的估算死亡率。（XLSX）
