Contact tracing and disease control

K. T. D. Eames, M. J. Keeling
2003 Proceedings of the Royal Society of London. Biological Sciences

Epidemic contact tracing with smartphone sensors [article]

Khuong An Nguyen, Zhiyuan Luo, Chris Watkins
2020 arXiv   pre-print
To this end, this paper proposes a novel, yet practical smartphone-based contact tracing approach, employing WiFi and acoustic sound for relative distance estimate, in addition to the air pressure and  ...  However, one of the challenges for technology based contact tracing is the high number of false positives, questioning its trust-worthiness and efficiency amongst the wider population for mass adoption  ...  The third result has a strong implication for contact tracing, as these detections are clearly not in the contagion range, and may trigger a false positive.  ...

Centralized or Decentralized? The Contact Tracing Dilemma [article]

Serge Vaudenay
2020 IACR Cryptology ePrint Archive

Optimizing the order of actions in contact tracing [article]

Michela Meister, Jon Kleinberg
2021 arXiv   pre-print
In this work, we develop a formal model that articulates these questions and provides a framework for comparing contact tracing strategies.  ...  Contact tracing is a key tool for managing epidemic diseases like HIV, tuberculosis, and COVID-19. Manual investigations by human contact tracers remain a dominant way in which this is carried out.  ...  Specifically, Armbruster and Brandeau consider a network model where a tracer with limited capacity must decide at each step which contact to trace next.  ...
