Contact patterns between individuals are an important determinant for the spread of infectious diseases in populations.

We found that the number of contacts was overall consistent from year to year, while the choice of trading partners tended to vary. This livestock movement network illustrated how a small number of farms central to the network could play ..View full abstract
