Reduction in undiagnosed HIV infection in the European Union/European Economic Area, 2012 to 2016

Members of the Ecdc HIv/Aids Surveillance And Dublin Declaration Monitoring Network: Portugal: Isabel Aldir, Helena Cortes Martins, Teresa Melo.It is well-documented that early HIV diagnosis and linkage to care reduces morbidity and mortality as well as HIV transmission. We estimated the median time from HIV infection to diagnosis in the European Union/European Economic Area (EU/EEA) at 2.9 years in 2016, with regional variation. Despite evidence of a decline in the number of people living with undiagnosed HIV in the EU/EEA, many remain undiagnosed, including 33% with more advanced HIV infection (CD4 < 350 cells/mm3).
