Relative reduction (in %) of reproduction number R0,m of the VPI compartment farms as function of the reduction in transmission probability (10, 50, 90%) of a specific route, due to biosecurity measures within the compartment.

Relative reduction (in %) of reproduction number R0,m of the VPI compartment farms as function of the reduction in transmission probability (10, 50, 90%) of a specific route, due to biosecurity measures within the compartment.VPI隔场（VPI compartment）养殖场的基本再生数R₀,ₘ的相对降低率（以百分比计），作为特定传播途径传播概率降低幅度（10%、50%、90%）的函数，其变化源于该隔场内实施的生物安全措施。
