Supplementary Material 6. Re-analysis of Morand et al. (2014) from Human infectious disease burdens decrease with urbanization but not with biodiversity

In our analysis, two diseases declined in burden in response to increasing population density over time, even though these diseases are expected to be transmitted in a density-dependent manner (i.e., measles, varicella). In this document, we compare these unexpected results to those of an earlier paper (Morand et al. 2014).
