Obiettivi formativi
The pervasiveness of the Web and mobile technologies as well as the growing adoption of smart wearable sensors have significantly changed the landscape of epidemic intelligence data gathering with an unprecedented impact on global public health. The digital traces generated by a large number of individuals interacting with Web and mobile technologies as well as wearable sensors contain epidemiological indicators that are not easily accessed with traditional approaches. Collectively, these digital sources largely enhance the capabilities of epidemiology and global public health. Indeed, since more than a decade, the growing field of digital epidemiology (https://www.ncbi.nlm.nih.gov/pubmed/?term=29302758) has been using digital data generated outside the public health system to carry out epidemiological studies on an unprecedented scale and with an unprecedented precision.
The goal of this course is to provide an overview of the main success stories collected during the first ten years of this young and exciting field. Moreover, the students will be guided on a few case studies with a hands-on approach.

Risultati dell'apprendimento attesi
By the end of the course the students will have the following:
- have a knowledge of the state-of-the-art research in the young and growing field of Digital Epidemiology.
- be able to collect data from digital proxy sources such as Google Trends, Wikipedia, Twitter etc.
- be able to design models for inferring and predicting epidemiological indicators from proxy data.
