Summary of HIV Epidemics in the European Region: Vulnerability and Response

Core Content

This report provides an analysis of HIV epidemics in the European Region, focusing on key populations at high risk of infection. It examines the current state of HIV surveillance, prevalence, and prevention efforts among people who inject drugs (PWID), sex workers (SWs), and men who have sex with men (MSM), and highlights the environmental and social factors that shape these epidemics.

Key Populations and Their HIV Risks

People Who Inject Drugs (PWID)

• HIV Diagnoses: Between 2006 and 2010, 25% of HIV case reports in Europe were associated with injecting drug use, with the highest rates in the East (33%) compared to the West (5%) and Centre (7%).
• Prevalence: The highest HIV prevalence among PWID was observed in Estonia (55.3%), Spain (34.5%), Russian Federation (28.9%), Republic of Moldova (28.6%), and Ukraine (22.9%).
• Risk Factors: Multivariate analyses linked HIV among PWID to injecting with previously used equipment, frequent injecting, and a longer history of injecting. Being female was also identified as a risk factor.
• Overlap with Sex Work: In the East, a significant overlap exists between sex work and drug injecting, with many SWs also being PWID and vice versa.

Female Sex Workers (FSWs)

• HIV Prevalence: HIV prevalence among FSWs is lower in the West (less than 1%) but higher in the East, ranging from 2% to 8%.
• Risk Factors: HIV prevalence is associated with injecting drug use, migration, and limited access to health services. SWs in the East also show higher rates of syphilis and other STIs, indicating potential for sexual transmission.
• Health Vulnerabilities: FSWs who inject drugs face higher risks of HIV, violence, mental health issues, and unwanted pregnancies.

Men Who Have Sex With Men (MSM)

• HIV Diagnoses: Sex between men accounted for 10% of all HIV case reports in Europe, with the highest proportion in the West (36%) and the lowest in the East (0.5%).
• Prevalence: HIV prevalence among MSM is highest in the West, ranging from 1.6% in Switzerland to nearly 20% in Spain. In the East, prevalence is lower but still significant.
• Risk Behaviors: Inconsistent condom use, unprotected anal intercourse (UAI), and a history of STIs are major risk factors for HIV among MSM.
• Core Group Dynamics: In the West, HIV epidemics are perpetuated by a core group of MSM engaging in high-risk behaviors with numerous partners. In the East and Centre, recent increases in case reports suggest a growing concern.

Main Findings

• Epidemic Trends: The HIV epidemic in Europe is growing, particularly in the East, where injecting drug use remains the primary mode of transmission.
• Case Reporting: Case reports among MSM are likely under-reported due to social stigma and legal restrictions on homosexuality.
• Prevalence and Risk: HIV prevalence is highest in the East, where PWID and SWs overlap significantly. In the West, HIV among MSM is more prevalent, while among FSWs, it is lower but still a concern.
• Migration Impact: Migration plays a significant role in the spread of HIV, especially among MSM. Migrants from countries with generalised HIV epidemics contribute to the spread in Western Europe.

Key Recommendations

• Strengthen Surveillance: Improve the accuracy of risk factor data among heterosexual exposures and expand surveillance to include sexual partners of PWID.
• Targeted Prevention: Focus HIV prevention efforts on PWID and their sexual partners in the East, and on MSM in the East and Centre, while reinvigorating prevention among MSM in the West.
• Integrated Interventions: HIV prevention responses should integrate sexual health and drug-related health services.
• Address Social and Structural Factors: Interventions should address the social-structural determinants of HIV risk, including stigma, legal status, and access to health services.
• Support for Sex Workers: Interventions among SWs should include sexual risk reduction in non-paying and regular relationships, and address the specific vulnerabilities of SWs who inject drugs.

Environmental and Structural Factors

• Legal and Social Contexts: The legal status of sex work varies across Europe, with many countries in the East having more restrictive laws, contributing to under-reporting and increased vulnerability.
• Policy Environments: The policy environments for PWID in the East are more restrictive, affecting access to harm reduction services.
• Migration and HIV Dynamics: Migration, especially among MSM, influences HIV transmission dynamics, increasing the risk of spread in both source and destination countries.

Conclusion

The HIV epidemic in Europe is most severe in the East, driven primarily by injecting drug use and the intersection of sex work and drug use. While the West is also affected, the epidemic is more closely linked to sexual transmission among MSM. Surveillance and prevention efforts must be adapted to reflect these regional differences, with a focus on high-risk groups and the structural factors that contribute to their vulnerability.
