The document discusses how perspectives on the AIDS epidemic have evolved over time from a focus on viral transmission and risk behavior in the 1980s-1990s, to disease progression and treatment in the late 1990s-2000s, to impact mitigation and support for those affected from the 2000s onward. It also examines how different groups have constructed different narratives around AIDS and how problem frames have shifted from individual risk to structural vulnerability to rights and citizenship. Key differences between AIDS and other epidemics discussed are its slow progression, invisibility, association with stigma, and unprecedented mobilization of affected groups globally and locally.
