It's a big moment for European researchers who study how phone location data could guide responses to disease outbreaks. They’ve often felt ignored in past public health crises. Now they're part of government task forces or informally advising during the COVID-19 pandemic. 2/
Some European governments have been collecting phone location data from telecom companies to see if the public is complying with social distancing measures and national lockdowns. For privacy reasons, such data has been anonymized and aggregated for use on a zip code level. 3/
Contact tracing apps could be especially useful early on to quickly detect and isolate infected cases and their contacts before the coronavirus gets widespread. But still useful after the infections peak to help stem a second wave of infections. 6/ https://arxiv.org/ftp/arxiv/papers/2003/2003.12347.pdf
Individual European countries will make their own decisions on deploying contact tracing apps. But researchers working with governments emphasized the need to start with the strongest data privacy protection possible and explain tradeoffs if needed to keep public trust. 7/
Phone location data also has limitations in what it can reveal. Not everyone has a phone. Not everyone carries a single phone around with them all the time. Phone location data only shows concentrations of people and not necessarily sick people, unless you use other data. 8/
The same anthropologist also questioned whether government resources are best spent on collecting and analyzing phone location data during a pandemic. E.g. Mobile data not always necessary to recognize when people violate social distancing measures. 10/ https://www.nj.gov/oag/newsreleases20/pr20200325b.html
Also unclear how much usage of phone location data should get credit for Singapore, South Korea, and Taiwan having early success in containment. More significant could be early and widespread testing and other basic public health measures. 11/
On a final note, the Spanish government task force has put out an international survey to understand the social and economic impacts of both the pandemic and national restrictions on movement and gatherings.
