This commentary reflects on what has been learnt from government and public health responses to COVID-19, suggesting a tension between ‘business as usual’ forms of public health in the face of crisis, and the possibilities for a step-change towards a ‘healthy publics’ approach. We set out a range of ways that diverse, multiple publics have been implicated or brought into being during the COVID-19 pandemic, and we argue that these have generally been ignored or erased by agents or agencies of public health, keen to preserve certainty in their messaging and public confidence in their authority. We conclude with five principles for re-organising pandemic responses around a richer, more context-dependent and diverse account of ‘the public’.
