Given the farm-to-farm proximity in high pig production areas, local transmission is an important pathway in the spread of PRRSV; however, there is limited understanding of the role local transmission plays in the dissemination of PRRSV, specifically, the distance at which there is increased risk for transmission from infected to susceptible farms.

A large number of between-farm contacts with a pathogen stability >0. 8 were present in the vehicle network even with 100% cleaning effectiveness.

Here, we modeled nine modes of between-farm transmission pathways including farm-to-farm proximity (local transmission), contact network of pig farm movements between sites, four different contact networks of transportation vehicles (vehicles that transport pigs from farm-to-farm, pigs to markets, feed distribution and crew), the volume of animal by-products within feed diets (e. g. animal fat and meat and bone meal) to reproduce PEDV transmission dynamics.

Raw movement data were directly used to build a dynamic network on a realistic time-scale.
