Search giant Google is working with the University of Southampton and the European centers for Disease Control and prevention to trace the spread of the new crown virus through a large number of location data collected by smartphones, foreign media reported.It is reported that the company has shared with researchers a batch of anonymous data sets from services such as maps. Although the case can not be traced accurately, it is possible to show the spread of the epidemic over a period of time at the macro level.
The data are helping researchers analyze the relationship between the way the virus spreads in different countries and the rate of transmission, while also providing insight into the effectiveness of urban closure policies in European countries, people familiar with the matter said.
Nick ruktanonchai, an expert and lecturer in epidemiology of infectious diseases at the University of Southampton, said: "we are studying the movement in the center of the European Union as a whole and examining its significance for the prevention and control of the covid-19 epidemic.".
Using geographic location data, researchers were able to test and simulate different situations. For example, if countries do not actively take coordinated measures, what will they eventually face when lifting the closure measures.
To ensure that a second pandemic does not occur in the next few months, it is clear that researchers need to race against the clock to carry out relevant research.
