Spatial epidemiology of networked metapopulation: An overview

Lin WANG; Xiang Li

At the intra-subpopulation scale, aside from the empirical support from the data analysis of intra-urban human mobility (see Section 3), the feasibility of the "well-mixed" contacts assumption is also consistent with the recent findings on interactive patterns of human contact. For example, diverse digital instruments, e.g., wireless sensors [115] , active Radio Frequency Identification (RFID) devices [116, 117] , and WiFi [118] [119] [120] (we resort to the WiFi technology in our social experiments, due to its ubiquity in urban areas), have been deployed in realistic social circumstances to collect the data of human close proximity contacts [121] . The data analyses have unveiled an unexpected feature that the squared coefficient of variance is quite small for the distribution of the number of distinct persons each individual author/funder.
