Linguistic anthropologists examine how the distribution of languages, discursive practices, and literacies structure unequal social and political relations. Medical anthropologists trace health inequities and unequal distributions of health care. Nevertheless, little research explores health/communicative inequities, the sometimes fatal ways they intersect. This chapter documents a rabies epidemic in a Venezuelan rainforest. Healers, nurses, physicians, and epidemiologists failed to diagnose a mysterious disease that killed thirty-two children and six young adults in 2007–2008. As parents moved between healers, nurses, the local physician, and urban specialists, their efforts to share the knowledge they had amassed were increasingly sidelined. Local leaders, accompanied by a nurse, healer, anthropologist, and physician, launched their own complex knowledge-production process that juxtaposed political oratory, indigenous medicine, dispute mediation, narrative, epidemiology, and medicine. Identifying the disease clinically as bat-transmitted rabies, the team challenged racialized stereotypes and health/communicative inequities by taking their findings to national health officials and journalists.
