Abstract
We present a theoretical approach to control bovine brucellosis. We have
used individual-based modelling, which is a network-type alternative to
compartmental models. Our model thus considers heterogeneous
populations, and spatial aspects such as migration among herds and
control actions described as pulse interventions are also easily
implemented. We show that individual-based modelling reproduces the mean
field behaviour of an equivalent compartmental model. Details of this
process, as well as flowcharts, are provided to facilitate the
reproduction of the presented results. We further investigate three
numerical examples using real parameters of herds in the Sao Paulo state
of Brazil, in scenarios which explore eradication, continuous and pulsed
vaccination and meta-population effects. The obtained results are in
good agreement with the expected behaviour of this disease, which
ultimately showcases the effectiveness of our theory.
