The containment measures put in place are, from an epidemiological point of view, unprecedented. In this context, and in order to understand the evolution of SARS-Cov-2 transmission, it is necessary to evaluate how our contacts have changed in our population. In this way, it will be possible to introduce them in predictive models.
A research unit of the Institut Pasteur is setting up a survey in order to collect and analyze data concerning these contacts.
Through questions such as " Who were you in contact with before the lockdown?" "Who do you still see today?", it will be possible to better understand the impact of containment on our social and professional lives. More specifically, the survey will now identify the number of contacts we have each day, their frequency and by age group. For example, before the lockdown, children were in contact with many other children every day, especially at school. Similarly, an adult was in contact with his colleagues every day before the lockdown. Today, what exactly is the situation?
Gathering this information on a large scale is essential to refine the modelling in the context of containment, and thus allow modellers to better understand and analyse the spread of the virus in France during this particular period.
