EPJ Data Science Highlight - Controlling epidemics using mobile phone data

Mobile data can be (and has been) used to study a vast number of subjects related to human behavior. One of its potential applications is on epidemics, a complex field that is informed not only by healthcare, but also social interactions and human mobility. In this blog post, Stefania Rubrichi explains the context in which her team used a real mobile phone dataset in an attempt to better understand and tackle the spread of diseases. Their study was just published in the journal EPJ Data Science.

Epidemics represent an important healthcare challenge worldwide. In a world that is so densely populated and more interconnected than ever, it makes increasingly easier for pathogens to propagate. Approaches that can rapidly target subpopulations for surveillance and control are critical for enhancing containment and mitigation processes.

The key to effectively control epidemics is understanding their dynamics and anticipating the possible implications. However, modeling the inherent complexity of disease spread process represents an ever-evolving challenge, requiring continuing efforts at several levels and across a broad range of disciplines. In particular, human behavior factors, like mobility and social interactions, are crucial drivers for disease transmissions, as these can substantially alter the probability of encounters, patterns of exposure, and the likelihood of disease propagation. Modern epidemiology has recognized the increasing importance of such factors and, as a consequence, they are now at the centre of disease dynamics and control investigations.

Mobile phone data have recently offered a pervasive and ubiquitous opportunity to sense individual behavior in many aspects of daily life. Mobile phones have been one of the fastest growing technologies over the last decade, reaching urban and rural populations across all socio-economic spectrums, all over the globe. Associated data, so-called call detail records (CDRs), are automatically generated by phones and recorded at large-scale by carriers for billing purposes, providing extremely rich information on individuals’ displacements and communication activities. They have proven to be extremely useful in research studies turning these data into actionable information and identified as a critical element to support global and sustainable development.

Using a real-world dataset from Ivory Coast, our work presents an attempt to unveil the sociogeographical heterogeneity of disease transmission dynamics. By employing a spatially explicit meta-population epidemic model derived from pseudoanonymized mobile phone CDRs, it investigates how the differences in mobility patterns may affect the course of a hypothetical infectious disease outbreak. It considers different existing measures of the spatial dimension of human mobility and interactions, and analyses their relevance in identifying the highest risk sub-population of individuals, as the best candidates for isolation countermeasures. The approaches presented in our paper provide further evidence that mobile phone data can be effectively exploited to facilitate our understanding of individuals’ spatial behaviour and its relationship with the risk of infectious diseases’ contagion. In particular, they show that CDRs-based indicators of individuals’ spatial activities and interactions hold promise for gaining insight of contagion heterogeneity and thus for developing effective mitigation strategies to support decision-making during country-level epidemics.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
