文摘

We prove that local BRN is to be greater than unity is neither necessary nor sufficient for epidemic outbreaks. By abandoning the well-mixed assumption and considering the heterogeneity of human interaction intensity, we observe more realistic spatiotemporal patterns of epidemic spreading. We can identify critical paths for preventing nationwide epidemic outbreaks in the future. By defining proper distance according to human mobility, we can map the observed levy-flight-like spreading process back to classical diffusion process and qualitatively predict the spreading paths.
