Coronavirus Pandemic (COVID-19)
What the data can and cannot tell us about the pandemic
Without data we can not understand the pandemic. Only based on good data can we know how the disease is spreading, what impact the pandemic has on the lives of people around the world, and whether the counter measures countries are taking are successful or not.
But even the best available data on the coronavirus pandemic is far from perfect.
In dedicated pages we present the latest data together with detailed explanations of what we can learn from this data: where does the data come from? What are the limitations that we need to be aware of? And what does the data tell us about the coronavirus pandemic?
The global data on the pandemic in detail:

Without testing for the virus there is no data on the pandemic. This is why we made testing the focus of our research.
