Country distancing increase reveals the effectiveness of travel restrictions in stopping COVID-19 transmission
Abstract
Network approaches are key to understand epidemic spreading, inherently driven by human mobility patterns and constrained by transport systems. In this work, the authors develop a country distance framework to capture the spread of COVID-19 on top of the airline network, analyzing the effectiveness of mobility restrictions in the presence of multiple outbreaks and suggesting strategies for optimized coordinated travel restrictions.
