It is characterized by a rather complex transmission dynamics that led previous work to focus exclusively on within-herd scale.
In our work we introduced a metapopulation model at the national level considering within-farm transmission dynamics at the animal level and cattle trade between farms as a driver for spatial dissemination. We focused on Italy, a country where BVD is endemic and seroprevalence is very high. We found that dairy farms are the main drivers of BVD persistence in Italy, and any control strategy targeting these farms would lead to significantly higher prevalence reduction, with respect to targeting other production compartments.
