At the same time, new technologies have exponentially raised the volume and complexity of digital data resulting from everyday consumer transactions, physical movement, communication, and healthcare. The emerging field of data science is the key to organizing these mountains of data and transforming them into the knowledge needed to devise rapid and effective responses to epidemics and the disruptions they bring to developing economies and global supply chains.
