In this article, we begin by discussing approximately thirty picture books dealing with the COVID-19 pandemic published digitally in the United States, the United Kingdom, Australia, and other English-speaking countries in the first six months of 2020. The worldwide impact of COVID-19 resulted in the rapid global digital publication of numerous English-language children's picture books aimed at informing child readers about public health concerns and how children could contribute to improving health outcomes. This exploration of contemporary picture books is intertwined with examinations of two other public health crises that appeared in literature for children: the discussion of British children's health in the Junior Red Cross Magazine in the 1920s and the American polio outbreak discussed in educational materials and fiction in the 1940s and 1950s. These comparisons not only enable us to situate the COVID-19 pandemic within a history of transnational responses to concerns about children's health but also to expand our understanding of how children are positioned to take individual responsibility for community public health issues. This wide range of Anglophone texts published in the United Kingdom, the United States, and around the world demonstrates the extent to which adults attempt to guide children towards specific behaviours to promote individual health. They also reflect a common understanding of childhood in which children have an obligation to contribute to societal wellbeing through their individual actions.
