Figure 4. Probability of a disease invading the cattle population of the Savannah Region in Togo through cattle trade from Burkina Faso.

The probability of a disease invading the cattle population of the Savannah Region is shown as a function of the disease prevalence in Burkina Faso and the basic reproduction number of the disease, R₀. Here, R₀ relates to the potential of a disease to invade the Savannah cattle population following the introduction of an infectious animal into one of its herds.
