The start of the new year has unshakeable feeling of Groundhog Day to it. We’re not even a week into January, and already epidemiologists are warning of new Covid variants, while passengers travelling from China to the UK will once again be required to show a negative Covid test before boarding. Many of us have been left wondering: have we woken up in 2023 — or 2020?

As the past year came to an end, the same stubborn arguments which have been spinning around the world’s hamster wheel for the last three years were aired again — this time about China’s decision to abandon Zero Covid, and what this might mean for the rest of the world in terms of variants, Covid spread and the health of the general population. We don’t want to rehearse these arguments again, but they are vital: they cut to the heart of what lessons global societies will take from the Covid-19 pandemic and associated policy response, and how institutions will balance health and disease in the future. It’s too easy to say that we should just move on, because the future health of human societies depends on what decisions now are taken.
