What do we know today about Corona and the way it spreads? Why do different countries act differently in reaction to the pandemic? Why are large events forbidden while schools are still open? Why are not everyone with symptoms tested for the virus? During this seminar, we strive to answer as many questions about the virus as possible from an epidemiologist's point of view. Live streamed webinar from the 18th of March with Johanna Adami, epidemiologist and president at Sophiahemmet University, in a conversation with our director Gustaf Arrhenius. The seminar was only broadcasted to our youtube-channel with questions from online viewers.
