What is it about?
Network analysis is important to know the relations between animal disease interactions. Our paper explains the implications of the movements of pigs. We have shown for the first time the static and spacial properties of the Ecuadorian network where more than half of the movements originated or were destined to markets (55%). Backyard producers made up 89% of the network premises, and the top 2% of parishes (highest degree) contributed to 50% of the movements. Centrality measures were calculated and identified 5 trading communities demonstrating that the network contributed to the transmission of classical swine fever.

Why is it important?
Our findings show the characteristics of the movements of pigs, which are quite important because of the application in the surveillance system to improve its procedures and update the disease control and management policy. To improve the mechanism of diseases surveillance, we hope targeted or risk-based surveillance could be implemented based on the results.

Vectors were plotted according to movement weights, and parishes were coloured by monthly in/out/balance degree. B: ingoing–outgoing mobilised pigs (parishes codes). C: percentage of accumulated active nodes. D: monthly movement weights. E: active edges
