Brucellosis model fitting for the annual cases of human brucellosis infection with different Cases. The light grey shaded area shows the 95% confident interval (CI) for all 1000 simulations, and the blue circles mark the reported data for human brucellosis cases. Let $x\left(t\right)$ represent annual cases of brucellosis infection, and $x\left(t\right)=X\left(t\right)-X(t-1)$, where $\frac{dX\left(t\right)}{dt}=\sigma E_h\left(t\right)$.
