In The Borders of AIDS, Karma Chávez demonstrates how such calls proliferated and how failure to impose a quarantine for HIV-positive citizens morphed into the successful enactment of a complete ban on the regularization of HIV-positive migrants—which lasted more than twenty years.News reports, congressional records, and AIDS activist archives reveal how queer groups and migrant communities built fragile coalitions to fight against the alienation of themselves and others, asserting their capacity for resistance and resiliency.Building on existing histories of HIV/AIDS, public health, citizenship, and immigration, Chávez establishes how politicians and public health officials treated different communities with HIV/AIDS and highlights the work these communities did to resist alienation.
