Effect of non-livestock hosts on the Floquet ratio R
for a sparsely populated livestock area. The R
was calculated for an area with livestock density of 200 animals per 5 × 5 km and on the x-axis the number of additional hosts per livestock host. Additional hosts were either refractory (i.e. birds), susceptible with shorter infectious period (i.e. rodents), or susceptible and equal to livestock characteristics.
