The coronavirus has brought science back to the centre, including in countries where populist leaders used to delegitimize it. Epidemiologists, medical doctors and biologists bring us hard facts: the pandemic progresses every day; it is far worse than a “strong flu” and takes thousands of lives on all continents. Social scientists have come up with facts that are as hard and as unquestionable: while the virus itself is a biological agent that may infect each of us, we are deeply unequal when confronted to it.
