![]() If it does, the person who owns the cell phone is labeled as potentially hospitalized. Another plus point is that the method works with anonymized data and can be run on the operator’s premises under its standard security provisions.Īccording to Laoutaris, the method works as follows: “We check the location of a phone late at night and if it is not connected to the usual phone towers it was connected to in the pre-pandemic era, we see if it was connected to a tower near a hospital that is receiving COVID patients. And that’s how you study the spatio-temporal mobility of people,” she adds. You don’t need to have GPS enabled and an application downloaded.” “When you have mobile data connected, your device connects to a cell tower that identifies your location radius. ![]() The paper “Improving epidemic risk maps using mobility information from mobile network data” will be published at the ACM SIGSPATIAL conference in November 2022.Ĭabana explains that the main advantage of the proposed solution is that, unlike Contact Tracing, “the data is already available at the operator and progress is faster. Now an IMDEA Networks research team led by Elisa Cabana (Postdoc researcher) and Nikolaos Laoutaris (Research Professor), in collaboration with Andra Lutu (Teléfonica Research) and Enrique Frías-Martínez (Camilo José Cela University), has carried out a study in which they propose a method that uses mobile network data to detect possible hospitalizations due to COVID-19 and obtain the corresponding epidemic risk maps. However, for these apps to be truly effective they require a large number of people to have them installed on their devices, and they also involve certain privacy risks. A few months later, as mobility restrictions and confinements were gradually lifted, states decided to launch tracking apps that citizens could download to their cell phones to find out if nearby contacts were infected with COVID. The onset of the COVID-19 pandemic in March 2020 forced governments around the world to take measures to prevent its spread among the population and, thus, reduce the number of fatalities as a result of the virus.
