16. HIV/AIDS Epidemiology in Vietnam

17. HIV and AIDS in Vietnam (1) • 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) • HIV is concentrated in certain high risk populations • IDU transmission in concentrated areas • Heterosexual transmission predominant in Mekong delta area

18. 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)

19. HIV and AIDS in Vietnam (3) • Most HIV infections in children are vertical transmission • National Sentinel Surveillance Data: • HIV prevalence in Vietnam 0.5% • HIV-1 prevalence in antenatal women 0.4% (0-1.9%) • 1.5-2 million births per year • 6000-7000 babies exposed to HIV at birth
