Overall structure of the network; dense circular groupings of black dots represent different locations.

The inset shows a close-up of two such groupings, and one possible arrangement of links within and between them. Long black lines connect some locations, representing potential movement-related connections, and thus opportunities for mosquito-mediated transmission of RVFV between cows from different locations. The inset expands a small portion of the contact network showing the dense circular masses are made up of small black circles, each of which represents 20 cows and correspond to the nodes shown in the representative contact network. Likewise, the black lines among these nodes represent possible connections within and between locations in the inset.
