This paper analyzes the bond as a strategy for practices of care in public health policies. The analysis was structured around the Foucauldian tools of truth and forms of government that constitute policies of subjectivation. The discussion surrounds the correlation between the National Policy of Primary Health Care and other documents of public policies as part of this approach that makes it possible to consider the articulation of the bond with practices of care. This reflection has considered the bond as a focus of experience constituted by the correlation between formation of knowledge, normativity of behaviors and forms of subjectivation with regard to a pragmatic of the subjects in their different modalities of relationship with themselves.
