Simulated JD dynamics.
A), An illustration of MAP transmission in a farm when incubation, , for the silent stage is varied from 4 months to 12 months in steps of 2 months. Qualitatively similar simulations are achieved with different combinations of parameters as long as . At any given time . B) Comparative analysis of cattle population at different disease stages in different time regions (see Table 3 for ratios in different regions). Simulations were carried out using parameters given in Table 2 with (cattle natural death rate).
