This article examines the month-long epidemic outbreak of Asian Flu in 1957 in the Colony of Singapore that occurred as part of the larger 1957–58 Asian Flu Pandemic. The notably short duration of this epidemic outbreak in Singapore relative to the prolonged Asian Flu experience in other countries poses significant socio-historical intrigue. In response, this article constructs a socio-historical narrative of Singapore's societal response to the event, focusing specifically on the reactions of the state and the colony residents. Studying the social narratives that emerged from official and popular discourses, this article argues that Singapore's societal response to the epidemic outbreak bifurcated drastically between the state and the public as a result of different and contradictory perceptions of public health and epidemic severity. Owing to extenuating circumstances, state interventions were, overall, reactive and insufficient, permitting the Asian Flu's rapid spread in the colony. The public, however, sought active control over their epidemic fates, as they were driven by a mixture of fear, greed, and civic duty to self-medicate, profiteer, and provide aid to one another. Consulting an eclectic range of hitherto underutilised primary sources, the article constructs a compelling socio-historical narrative that furthers understanding of Singapore's state-society relations.
