An analysis of the spread of the corona virus


How does the virus spread? An analysis of the spread of the corona virus with the help of data and network science – online lecture Tuesday March 31 at 11:00:

María Óskarsdóttir, Assistant Professor at the Department of Computer Science at Reykjavik University explains in a short lecture how data and network science are used to analyze the spread of the SARS-CoV-2virus. In this presentation we will talk about the methods that scientists are using to understand the spread of the corona virus that causes COVID-19. A lot is unknown about the nature of the virus, how it transfers from person to person and how infectious people really are, both before and after they get sick. In addition, only a fraction of those who are infected actually get diagnosed. In order to estimate these unknowns, scientist turn to data science and various types of data. 

For example, mobile phone data was used to estimate how many people travelled from Wuhan in China before travel ban. This number was then compared to the number of confirmed infections in cities where systematic tests were conducted. In this way, the scientists estimated the real number of infected people in Wuhan and the number of infected people that travelled to other countries. Another group of scientist used network science and a disease transmission model to project he impact of travel restrictions on the epidemic, both within China and worldwide. In the presentation we will discuss these studies and their meaning in the battle against the corona virus.
