Abstract The analysis of connection strengths and distances in the mobility network is pivotal for delineating critical pathways, particularly context epidemic propagation. Local connections that link proximate districts typically exhibit strong weights. However, ties bridge distant regions with high levels interaction intensity, termed long (SL) ties, warrant increased scrutiny due to their potential foster satellite clusters extend duration pandemics. In this study, SL are identified as outliers on joint distribution distance flow Shanghai constructed from 1 km × high-resolution data. We propose a grid-joint isolation strategy alongside reaction–diffusion transmission model assess impact findings indicate connected by small spatial autocorrelation display temporal similarity pattern disease transmission. Grid-joint based reduces cumulative infections an average 17.1% compared other types ties. This work highlights necessity identifying targeting potentially infected remote areas spatially focused interventions, thereby enriching our comprehension management dynamics.

In recent years, a range of novel smartphone-derived data streams about human mobility have become available on near-real-time basis. These been used, for example, to perform traffic forecasting and epidemic modeling. During the COVID-19 pandemic in particular, travel behavior has considered key component epidemiological modeling provide more reliable estimates volumes pandemic's importation transmission routes, or identify hot spots. However, nearly universally literature, representativeness these data, how they relate underlying real-world mobility, overlooked. This disconnect between reality is especially relevant case socially disadvantaged minorities.
