Abstract
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).

It is well-documented that early HIV diagnosis and linkage to care reduces morbidity and mortality as well as HIV transmission
Despite evidence of a decline in the number of people living with undiagnosed HIV in the European Economic Area (EU/EEA), many remain undiagnosed, including 33% with more advanced HIV infection (CD4 < 350 cells/ mm3)
In order to understand regional variations in (i) HIV incidence, (ii) time to HIV diagnosis, and (iii) the number of people living with undiagnosed HIV, we analysed HIV and AIDS surveillance data from 2003 through 2016
Summary
Reduction in undiagnosed HIV infection in the European Union/European Economic Area, 2012 to 2016. 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. In order to understand regional variations in (i) HIV incidence, (ii) time to HIV diagnosis, and (iii) the number of people living with undiagnosed HIV, we analysed HIV and AIDS surveillance data from 2003 through 2016. The ‘incidence method’ in the European Centre for Disease Prevention and Control (ECDC) HIV Modelling Tool version 1.3.0 was used for each region in 2016 to estimate the (i) HIV incidence, (ii) median time from infection to diagnosis, and (iii) number of people living with HIV who were not yet diagnosed [5,6]. Rates in 2010–2015 had ranged from 6.5 to 6.7 and in 2016, for the first time in a decade, there was a clear decline in the rate of new HIV diagnoses at EU/EEA level rates in 11 of 31 EU/EEA countries have continued to increase
