Abstract
This article analyzes images from two historical moments of HIV/AIDS in Chile. The first of these, dates back to the 1980s, and includes press images and the works of Juan Dávila and the Yeguas del Apocalipsis. The second register explored belongs to bareback sex communities in Chile and its social networks. The analysis uses the ideas of community/immunity, especially by Roberto Esposito, to observe some notions of community limits. It is established that, considering significant differences about the purposes of the images, they show the changes in the culture on HIV / AIDS in Chile, and the passage from a culture of the immune based on fear, to another, in which there are groups that promote practices of community “contagion”.
