​New data for 2011 show that more than 121 000 new HIV cases were reported in the WHO European Region, including more than 28 000 new infections in the European Union and the European Economic Area (EU/EEA), indicating an increase for the whole Region compared to the previous year1.

Almost 30 000 newly diagnosed HIV infections were reported by the 31 European Union and European Economic Area (EU/EEA) countries in 2015, according to data published by ECDC and the WHO Regional Office for Europe. This is similar to the observed notification trends in the last decade. One reason for this persistent HIV epidemic: ECDC estimates that currently around 122 000 people living with HIV across the region are unaware of their infection. The estimated time between HIV infection and diagnosis is four years.
