Query: Network structure and disease risk for an endemic infectious disease   The structure of contact networks affects the likelihood of disease spread at
the population scale and the risk of infection at any given node. Though this
has been well characterized for both theoretical and empirical networks for the
spread of epidemics on completely susceptible networks, the long-term impact of
network structure on risk of infection with an endemic pathogen has been less
well characterized. Here, we analyze detailed records of the transportation of
cattle between farms in Turkey to characterize the global and local attributes
of the shipments network between 2007-2012, building an aggregated static
directed - weighted network. We study the correlation between network
properties and the likelihood of infection with, or exposure to, foot-and-mouth
(FMD) disease over the same time period using recorded outbreaks. The shipments
network shows properties of small-worldness and scale-freeness (intermediate
degrees), with an exponential cut-off for high degrees. The shipments network
illustrates strong modularity and lack of assortativity. The shipments network
shows signs of spatial constraints, with few long-distance connections, and a
strong similarity to other spatially constrained networks. We find that farms
that were either infected or at high risk of infection with FMD (within one
link from an infected farm) had higher values of centrality; farms that were
never less than 2 links from an infected farm had disproportionately low
centrality. However, the correlation of the rankings of farms shows that
central farms (high eigenvector centrality) are not necessarily those with more
connections to/from it (in/out degree). Several central farms serve as bridges
of densely connected farms (high betweenness centrality). These results suggest
that to detect FMD spread, surveillance efforts could be focused preferentially
on farms with centralities greater than the mean.
