2.3 Static network
We constructed contact networks in which premises were defined as nodes and movements between premises were considered edges. The consequent contact network \(g\) was based on the movements during the study and was represented as directed (\(g_{\text{ij}}\neq g_{\text{ji}}\)), such that where the origin (node\(\ i\)) and destination (node \(j\)) have a specific direction. We described the static network using data from all years of study as well as by year. Parameters that we measured are summarized in Table 2.
