Lorelei Koss, SIR Models: Differential Equations that Support the Common Good, in Linking Differential Equations to Social Justice and Environmental Concerns, ed. Samer Habre, special issue, CODEE Journal 12 (2019): Article 6. https://scholarship.claremont.edu/codee/vol12/iss1/6/

This article surveys how SIR models have been extended beyond investigations of biologically infectious diseases to other topics that contribute to social inequality and environmental concerns. We present models that have been used to study sustainable agriculture, drug and alcohol use, the spread of violent ideologies on the internet, criminal activity, and health issues such as bulimia and obesity.
