High uptake of antiretroviral treatment ART is essential to reduce human immunodeficiency virus HIV transmission and related mortality; however, gaps in care exist. Strengthening of testing programs and treatment support, along with prevention interventions, are needed to achieve HIV epidemic control. Standardized definitions were used to estimate a 4-stage continuum of human immunodeficiency virus HIV care in 11 European Union EU countries in The EU is close to the target, with the main challenge being the percentage of undiagnosed infections.
See the Editorial Commentary by Granich and Gupta on pages β9. Highly effective antiretroviral treatment ART reduces morbidity and increases the life expectancy of treated individuals living with human immunodeficiency virus HIV , as it is highly effective in suppressing HIV viral load [ 1 , 2 ]. Large studies on serodiscordant couples have provided evidence that virally suppressed individuals living with HIV have a negligible probability of transmitting the virus to their HIV-negative partner [ 3β5 ].
Nevertheless, in there were approximately 1. It is thus important for countries to regularly assess their progress toward achieving the target.
However, national cohorts are lacking. Thus, reduced cohorts that only include people accessing care are often used, risking to result in biased estimates [ 11 , 12 ]. The EU CoC for 11 countries in was estimated using common definitions and recommendations to address these methodological and data challenges [ 13β15 ]. Since then, most European countries have adopted the test-and-treat guidelines [ 1 , 16 ]; however, progress toward treatment and viral suppression targets may be uneven.
