There are five types of stigma surrounding HIV: enacted stigma involving negative reactions, internalized stigma which is self-directed, anticipated stigma regarding expectations of stigmatization, concealable stigma that can be hidden but carries internal weight, and associative stigma from association with someone who has HIV. Governments, world leaders, and activists can influence stigma by creating or ending it. Individuals can work to reduce stigma by spreading positive stories and educating others.
