The Continuum of Care Cascade ("the cascade") involves the steps HIV-infected individuals have to take in order to achieve viral suppression. It starts with knowing one's HIV status, continues with linkage to care after a positive HIV test, initiation of ART, uninterrupted continuation of ART (retention in care and adherence to medication), and ends with viral suppression (MacCarthy 2015). Already prior to announcement of the "seek-test-and-treat" approach, weaknesses in the cascade often hampered the effectiveness of HIV programs in resource-rich as well as resource-poor settings (Yehia 2015; Kratzer 2012). In Sub-Saharan Africa the care cascade is still far from the 90-90-90 targets with only 29% of infected individuals estimated to be on ART and virally suppressed in 2013. In order to achieve the UNAIDS targets innovative, effective, and practical approaches for improving the care cascade are thus urgently needed (Mills 2013; Piot 2015).
