Values represent medians (and interpercentile ranges) from a multivariate uncertainty analysis. R₀ values less than one (bold) indicate that the removed host species is essential for transmission. GH, Guanghui; HP, Heping; LQ, Longquan; LS, Longshang; XZ, Xingzhuang; YT, Yuantou.

^*Values for bovines represent overall R₀ values when transmission from both cattle and water buffaloes is removed.
