In the early 21st century, scholars began to pay increasing attention to various topics in the rhetoric of health and medicine. J. Blake Scott's 2003 book Risky Rhetoric: AIDS and the Cultural Practices of HIV Testing used Michel Foucault's theory of examination, which defines rhetoric as a form of disciplinary power, to examine the cultural condition that influence HIV testing.[17] He reported that the rhetoric used in public policy and various propaganda led to the stigmatization and discrimination of people with HIV/AIDS.
