PLHIV diagnosed and PLHIV treated: The first two stages of the HIV care continuum on the proportion of PLHIV with HIV diagnosis and treatment were derived from the RKI HIV estimates on PLHIV.

PLHIV with viral suppression: For the estimation of the number of people achieving viral suppression we analyzed data from two large German cohort studies, the ClinSurv HIV and the HIV-1 Seroconverter cohort both under the directive of the Robert Koch Institute. Cohort data from 1997-2015 was included in the analysis. For the analysis of persistent viraemia in the study population we developed a 10- day grid model to close gaps between documented viral load (VL) measurements. A period of 180 days was determined as time between ART initiation and viral suppression (VL<50 copies/ml). Persistent viraemia was defined as two consecutive VL measurements >50 copies/ml within 180 days or one VL measurement >1000 copies/ml
