Predictive models to counter the spread of the COVID-19 pandemic

22/12/2020 The working group led by epidemiologist Stefano Merler has been involved in national and regional government Task Forces (Lombardy, Veneto, Trentino) set up to respond to the Coronavirus emergency through transmissibility mathematical models.

The work of the research group focused on the production of dozens of alternative scenarios based on which decision-makers have made their choices.

The high level of the scientific results achieved can be seen from the journals that hosted the analysis conducted (SCIENCE, THE LANCET INFECTIOUS DISEASES, EUROSURVEILLANCE, JAMA).

In particular, the studies covered three geographical areas to which specific insights were dedicated: the Lombardy region, the most acute case on the national territory, Italy and China.

Among the aspects considered were the effectiveness of the restrictive measures adopted in Italy, the effects of travel restrictions from China on the spread of the virus in the world and the probability of developing symptoms following the infection of SARS-CoV-2.
