COVID-19 Pandemic

Between January 2020 and December 2022, we focussed on quantifying the epidemiology and evolution of SARS-CoV-2 in real-time.

We estimated the reproductive number for >180 countries on a daily basis and founded a large Swiss SARS-CoV-2 Sequencing Consortium revealing insights into the variant spread in Switzerland (see subpages). Results were communicated to and discussed with the relevant policy makers via the external page Swiss National COVID-19 Science Task Force (headed by Tanja Stadler Aug. 2021- March 2022) and the external page Swiss Scientific Advisory Panel COVID-19 (headed by Tanja Stadler Nov. 2022- June 2024). In parallel, we informed the public through the media (see list below).

Selected press coverage

General: Our estimates of the reproductive number are displayed graphically in the external page NZZ and the external page Tagesanzeiger and provided as text by the external page SRF.
