ABSTRACT
I will present an overview of the results of analyzing mobile phone data to create population mobility models in Cuba. In particular, I will present the impact of the NPIs limiting human mobility. We studied the Granger causality relation between the COVID cases time series in every Health Area in Havana and tried to predict the sequence in any given area based on the population mobility interaction between that area and other areas with cases. We show that at this level of detail, mobility is a negligible contribution to predicting new cases. However, extensive simulations on an e-Havana help to understand why it doesn't work, and when it does work as a predictor.
