Measuring the impact of epidemic alerts on human mobility using cell-phone network data

چکیده
Accumulating evidence reveals a strong link between human mobility and the spread of epidemics. In order to control the spread of an epidemic, governments can implement mobility restrictions to its citizens. The effect of such restrictions on the mobility of the population has not been adequately studied at a large scale mainly due to the lack of relevant data. Nevertheless, the recent adoption of ubiquitous computing technologies enables the design of such studies. In this paper we measure the impact that the alerts issued by the Mexican government had on the mobility of the Mexican population during the H1N1 flu outbreak in April and May of 2009. The mobility of individuals was characterized using anonymized Call Detail Records (CDRs) traces. The results indicate a statistically significant reduction, of up to 80% in some cases, in the diameter of mobility of individuals.

متن کاملOn the Use of Human Mobility Proxies for Modeling Epidemics
Human mobility is a key component of large-scale spatial-transmission models of infectious diseases. Correctly modeling and quantifying human mobility is critical for improving epidemic control, but may be hindered by data incompleteness or unavailability. Here we explore the opportunity of using proxies for individual mobility to describe commuting flows and predict the diffusion of an influen...
