Whereas the decreasing rates of AIDS diagnoses and AIDS deaths reflect relatively good access to therapy, the increasing numbers of new HIV diagnoses and relatively high prevalence of HIV among MSM suggest the need for Europe-wide HIV prevention among MSM.

Migrants, largely from SSA, represent a considerable proportion of AIDS and HIV reports in EU, especially among heterosexual and MTCT infections. Their contribution is higher among female reports. A substantial percentage of diagnoses in MSM are migrants, largely from Western Europe and Latin-America.

HIV-prevention measures specific to injection drug users (IDUs), such as opioid substitution treatment and needle-and-syringe programs, are not provided in many countries where injection drug use is endemic. We describe the incidence of diagnosed HIV infection in IDUs and the availability and coverage of opioid substitution and needle-and-syringe programs in the European Union and 5 middle- and high-income countries. Countries with greater provision of both prevention measures in 2000 to 2004 had lower incidence of diagnosed HIV infection in 2005 and 2006.

In 2009, 28 European Union and European Economic Area (EU/EEA) countries reported 25,917 newly diagnosed cases of human immunodeficiency virus (HIV). Sex among men who have sex with men was the most common transmission mode (35%) followed by heterosexual contact (24%). Overall, the number of HIV cases in 2009 increased while the number of reported acquired immunodeficiency syndrome (AIDS) diagnoses continued to decline. It is of concern that a high proportion of the patients with known CD4 cells count at the time of HIV diagnosis had a CD4 cell count below 350cells/µl suggesting no timely access to treatment and care.

Human immunodeficiency virus (HIV) infection remains of major public health importance in Europe, with evidence of increasing transmission of HIV in several countries. This article provides an overview of HIV and acquired immunodeficiency syndrome (AIDS) surveillance data, and indicates that since 2000 the rate of newly reported cases of HIV per million population has almost doubled in Europe. In 2007, a total of 48,892 cases of HIV infection were reported from 49 of 53 countries in the Region, with the highest rates in Estonia, Ukraine, Portugal and the Republic of Moldova. In the European Union (EU) and European Free Trade Association (EFTA) countries, the predominant mode of transmission for HIV infection is sex between men followed by heterosexual contact. Injecting drug use is still the main mode of transmission in the eastern part of the WHO European region, while in the central part heterosexual contact is the predominant mode of transmission. In 2007, the reported number of AIDS cases diagnosed decreased in the Region overall, except in the eastern part. HIV/AIDS surveillance data are vital to monitor the trends of the HIV epidemic and evaluate public health responses.

In 2012, newly reported human immunodeficiency virus diagnoses in the European Union /European Economic Area remained stable at around 30,000 cases. Since 2003, cases in men who have sex with men (MSM) aged 20 to 29 years-old doubled, while the proportion of late presenters in this group remained stable. Persistent declines occurred among older MSM age groups, particularly that between 30 and 39 years-old. Interventions targeting younger MSM are needed to prevent a resurgence of the epidemic in Europe.

In some eastern European countries public health interventions, such as deferring individuals at risk of HIV infection from donating blood and constituting a pool of regular donors, are urgently needed to assure the safety of the blood supply.
