  1. Overview of the State of the HIV Epidemic in Canada Regional Session on USA and Canada XIX International AIDS Conference Howard Njoo MD, MHSc, FRCPC Director-General Centre for Communicable Diseases and Infection Control Public Health Agency of Canada

  2. Outline of Presentation • Overview of Canada • HIV in Canada – Epidemiology • Drivers of New HIV Infections • Government of Canada’s Domestic Response to HIV • Conclusion

  3. Overview of Canada 3

  4. Canada 4

  5. The Public Health Agency of Canada 5

  6. The Centre for Communicable Diseases and Infection Control Mandate: To create and share credible knowledge and facilitate coherent national action which contributes to the prevention and control of specific communicable diseases, with a focus on key populations at risk CCDIC is responsible for the following communicable/infectious disease areas: HIV/AIDS, tuberculosis, sexually transmitted infections, bloodborne pathogens (hepatitis B & C), and healthcare associated infections, including antimicrobial resistance

  7. HIV Epidemiology in Canada 7

  8. Estimated HIV prevalence in Canada over time, with range of uncertainty, 1975-2008 8

  9. Estimated new HIV infections per year in Canada by exposure category,1981-2008 NB: Range of uncertainty omitted

  10. Estimated HIV incidence in Canada by sex, 2008 Note: Range of uncertainty omitted 10

  11. Estimated HIV incidence in Canada by ethnicity/country of birth, 2008 Note: Range of uncertainty omitted 11

  12. Rate (per 100,000 population) of HIV diagnoses in Canada among adults (≥15 years), 2000 and 2010 2000 2010 Rate per 100,000 0 – 6.0 6.1– 12.0 12.1 – 18.0 18.1 and higher Note: rate for the 3 northern territories together was calculated as combined 3-year average to adjust for small cell sizes and avoid outlier biases. 12

  13. Epidemiologic Summary • Increasing prevalence due to effective treatment and ongoing transmission • Prevalence is concentrated among certain key populations • Patterns of infection have shifted • New infections are not declining 13

  14. Drivers of New HIV Infections 14

  15. Key Populations and Risk Behaviours • Key populations: • gay and other MSM • people who use drugs • Aboriginal Peoples • women • youth at-risk • people from HIV-endemic countries • people in prison, • people living with HIV/AIDS • Risk behaviours: • Unprotected sex • Sharing of drug use equipment 15

  16. Determinants of Health and HIV Vulnerability • Social and structural risk factors include: • Stigma and discrimination: e.g. racism, sexism, homophobia, HIV-phobia • Mental health: affected by stigma and discrimination, in turn affects likelihood of engaging in risk behaviours • Health care: knowledgeable, culturally competent care affects access to prevention, diagnosis, and care • Social support: connection with family, friends and communities affects vulnerability

  17. Government of Canada’s Domestic Responseto HIV 17

  18. Government of Canada’s Domestic Response to HIV • Provinces and territories have primary responsibility for delivery of health care and public health services • Federal government plays several key roles: • Health service delivery for federal populations • National routine and enhanced surveillance • Public health guidance • Community programs, knowledge transfer and partnerships • Research • Laboratory services

  19. A Comprehensive Prevention Approach • Prevention a cornerstone of the Canadian response • Includes interventions at all levels: • Primary: e.g. condom distribution, behavioural counselling • Secondary: e.g. testing, diagnosis, care • Tertiary: e.g. treatment, support • Determinants of health: e.g. supportive housing, anti-stigma campaigns • Utilizes a range of interventions (biomedical, behavioural and structural)

  20. Conclusion • HIV remains a significant public health issue in Canada • Despite notable successes, prevention remains an ongoing challenge • The way forward: • Improving understanding of biomedical, behavioural and social/structural drivers of infection continues to inform program and policy • Evolution of approach – integrated approach to STBBI/TB prevention • Collaborative approach between governments, across sectors and with affected populations is key 20
