"The crisis which arose suddenly at the beginning of 2020 relating to coronavirus was immediately centred on risk. Predictions had to be made swiftly regarding how it would spread, who it might affect and what measures could be taken to prevent exposure in everyday social interaction, including in the workplace. This was in no way a straightforward assessment, because initially so much was unknown. Those gaps in our knowledge have since, partially, been ameliorated. It is evident that not all those exposed to COVID-19 become ill, and many who contract the virus remain asymptomatic, so that the odds on becoming seriously ill may seem small. But those odds are also stacked against certain segments of the population."
