The term "contagion" in literature has long transcended its literal association with disease to serve as a powerful metaphor for the spread of ideas, emotions, behaviors, and even cultural norms. Early sociologists like Burgess and Park used it to describe social phenomena such as fashion, moral influence, and even the transmission of taboo, equating imitation with a contagious process [1, 2, 3]. Durkheim and his successors extended this metaphor to explain how collective rituals and emotions ripple through communities, thereby imbuing social interactions with an almost infectious quality [4, 5, 6]. In dramatic and narrative works—from Shakespeare’s evocative depictions of deadly allure [7] to H. G. Wells’ portrayal of fear and collective hysteria [8, 9, 10, 11]—contagion captures both the tangible and intangible threats that spread among individuals. Even in discussions of magic and mysticism, authors invoke the law of contagion to explain both the binding power of symbolism and the potent transfer of spiritual influence [12, 13]. This rich tapestry of usage underscores "contagion" as a versatile concept that illuminates both the dynamics of physical infection and the less tangible epidemics of social and moral behavior.
