Title: The effect of inter-city travel restrictions on geographical spread of COVID-19: Evidence from Wuhan, China Document date: 2020_4_21
ID: 6kiv3qi5_15
Snippet: We extended the corresponding outflow time series to to the early stages of the outbreak (22 November 2019), by assuming the outflow from Wuhan to equal to the average daily outflow on representative non-Chunyun days, whilst accounting for weekday effects. The pairwise travel flow proportions between Wuhan and each other prefecture-level city was only available between 1 January -1 March, 2020, so an approximation of the general flow magnitude wa.....
Document: We extended the corresponding outflow time series to to the early stages of the outbreak (22 November 2019), by assuming the outflow from Wuhan to equal to the average daily outflow on representative non-Chunyun days, whilst accounting for weekday effects. The pairwise travel flow proportions between Wuhan and each other prefecture-level city was only available between 1 January -1 March, 2020, so an approximation of the general flow magnitude was used for dates outside of the observed range (22 November -31 December) and in simulated aspects of our scenarios i.e. Chunyun affected travel days in non-Chunyun scenarios. A more detailed description of how each scenario was formulated is in Supplementary Appendix 3.
