(a) Distribution of D values. Note that D > 0.02 represents the tail of the distribution. (b) Var linkage clique: DBLα types 20, 19, and 11 were found to correlate strongly with one another, (c) Significant modularity in a DBLα type linkage network. D values >0.02, only single infections. The different colors of the nodes correspond to the different identified modules. We find significant modularity in this network when compared to randomizations that preserve the degree distribution (p < .00001). The colors of the nodes correspond to the colors in Figure 6. We identify five modules, and the modularity is ~0.28. The modularity of the null networks is approximately half this observed value
