This paper proposes that public health is the sort of institution that has a role in producing structures of virtue in society. This proposal builds upon work that describes how virtues are structured by the practices of institutions, at the collective or whole-of-society level. This work seeks to fill a gap in public health ethics when it comes to virtues. Mainstay moral theories tend to incorporate some role for virtues, but within public health ethics this role has not been fully articulated. Two recent papers have proposed ways in which the virtues might be incorporated: working from a structural account, Rozier suggests that public health could work to instil virtues, like temperance, in the public in order to achieve its health-related goals; Nihlén Fahlquist suggests that compassion is among three virtues that practitioners of public health should cultivate in order to do their work well. In the end, both accounts recommend incorporating virtues at the level of individuals, among the public and among practitioners. I propose a third kind of role for virtue in public health that focuses on structures. Public health activities take place at the population level, and a public health virtue ethics must also be suitably population-focussed.
