Supermarket stockpiling, A-level results and Covid-19 gender disparity

This week, we examine criticisms of Imperial College’s epidemiologists. We ask how A-Level and GCSE grades will be allocated, given that the exams have vanished in a puff of social distancing. Adam Kucharski, author of The Rules of Contagion, tells us about the history of epidemiology. We look at the supermarkets: how are their supply chains holding up and how much stockpiling is really going on. And is coronavirus having a different impact on men than on women?
