Use of temporal contact graphs to understand the evolution of COVID-19 through contact tracing data

[摘要] Contact tracing using mobile phones has been a strategy used by many countries to limit the spread of COVID-19. Here, the authors use location-related phone data from Wuhan to construct a temporal contact graph and demonstrate a strong correlation between contacts level and epidemic size, thus justifying the effectiveness of the approach.
