Behaviour of the epidemiological model of PRRS virus spread and control in a population of 50 herds when assuming no intervention from the social planner (5 000 replications).

<p>(A) Median number of virus-free herds (<i>F + Fd</i>). (B) Median number of infected controlled herds (<i>I</i>_<i>C</i>). The 90% confidence interval [5^th percentile; 95^th percentile] was provided for each graph in light blue. (C) Contribution of each tested parameter to output variance (<i>β</i>_<i>I</i>, , <i>out</i>,<i>γ</i>,<i>α</i>,<i>ν</i>,<i>κ</i>,<i>φ</i>,<i>δ</i>) after 50 years with the principal effect in blue and the effect associated to first order interactions in red (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0197612#pone.0197612.t002" target="_blank">Table 2</a> for parameter definition).
