Values represent medians (and interpercentile ranges) from a multivariate uncertainty analysis. R₀⁽ⁱ⁾ values above one (bold) indicate maintenance host species. GH, Guanghui; HP, Heping; LQ, Longquan; LS, Longshang; XZ, Xingzhuang; YT, Yuantou.

^*Values for bovines represent those values for cattle and water buffalo combined (calculated from the largest eigenvalue of a next generation matrix of transmission among cattle and water buffalo only).

^†Overall R₀ values calculated from the largest eigenvalue of the next generation matrix for transmission among all host species.
