SOCRATES: An online tool leveraging a social contact data sharing initiative to assess mitigation strategies for COVID-19


Objective: Establishing a social contact data sharing initiative and an online tool to assess mitigation strategies for COVID-19. Results: Using our online tool and the available social contact data, we illustrate that social distancing could have a considerable impact on reducing transmission for COVID-19. The effect itself depends on assumptions made about disease-specific characteristics and the choice of intervention(s). Keywords: Social contact data, Data sharing initiative, User interface. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement This work is part of a project that has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement 682540 — TransMID) (TVH, PC and NH).
