  10. HIV/AIDS Epidemiology in Vietnam

  11. HIV and AIDS in Vietnam • First case of HIV in Vietnam was diagnosed in 1990 • HIV cases have been reported in 100% of provinces and 97% of districts (VAAC, 2011) • National prevalence rate among adults is 0.44% (VAAC, 2009) • HIV is concentrated in certain high risk populations

  12. Reported Cumulative Cases of HIV, AIDS and Deaths in Vietnam, by Year

  13. Number of HIV Cases by Province VAAC – MoH, 2010

  14. HIV Prevalence by Province HIV cases per 100,000 population (Source: VAAC – MoH, 2010)

  15. Distribution of HIV Infection in Vietnam, by Age (Source: VAAC – MoH, 2010) 15

  16. Distribution of HIV Infection by Gender VAAC, 2010

  17. Distribution of HIV Cases by Risk Group (VAAC – MoH, 2010) Most cases are among IDUs (52% of total cases)

  18. Projections of HIV/AIDS Infection in Vietnam between 2004 - 2012 Viet Nam HIV/AIDS Estimates and Projections 2007-2012, VAAC, 2009

  19. Who will the Patients be in the Future?New HIV Infections by Sub-population

  20. Characteristics of HIV Epidemic in Vietnam (1) • The number of people living with HIV in Vietnam is increasing • The epidemic is concentrated in high risk groups • Two concurrent epidemics: • IDU transmission in concentrated areas • Heterosexual transmission predominant in Mekong delta area

  21. Characteristics of HIV Epidemic in Vietnam (2) • Shift in the HIV epidemic toward: • Young people from <29 year olds • Female • Non-IDUs • General community (heterosexual transmission) • Men who have sex with men (MSM)

  22. National Strategy on HIV/AIDS Prevention and Control Overall objectives: • Reduce national HIV prevalence to 0.3% • Reduce adverse impact of HIV/AIDS on social-economic development

  23. Future Priority Activities for Vietnam • Strengthen Information, Education and Communication (IEC) activities to change unsafe behaviors • Enhance harm reduction interventions • Increase HIV counseling, care, treatment • Build capacity in program management, monitoring and evaluation

  24. Key Points • HIV epidemic continues to expand globally • Increasing in Vietnam, particularly: • Concentrated in high risk groups (IDUs, sex workers, MSM) • Among young people and women through IDU, unsafe sex • National HIV prevention and control strategies include: • Focus on IEC to change risk behavior • Increase harm reduction • Scale up access to ARV care and treatment
