Well into the Third Decade:Key Points About the Global Epidemic: 

Well into the Third Decade: Key Points About the Global Epidemic Global pandemic – HIV/AIDS found throughout the world, in every region Earlier projections surpassed. HIV/AIDS on track to be the worst epidemic in history We may still be in the epidemic’s early phase HIV/AIDS is really multiple epidemics (different populations, levels, regions) Figure 1

Key Points Continued…: 

Key Points Continued… Certain populations at particular risk – youth, women, men who have sex with men, injection drug users – but generalized epidemic in many countries Hardest hit countries are least equipped to respond Multi-sectoral impact, 'collateral' effects: development and economic growth, education, food supply, communities, households, and individuals We know a lot and very little… Figure 2

Current Global Estimates: 

Current Global Estimates Sources: UNAIDS, AIDS Epidemic Update, December 2004; World Health Organization, The World Health Report 2004. 39.4 million estimated to be living with HIV/AIDS worldwide 4.9 million new infections in 2004 (almost 14,000 each day) 3.1 million deaths in 2004 (more than 8,000 deaths per day) Most people with HIV/AIDS (95%) reside in low and middle income countries, where most AIDS-related deaths occur HIV is now the leading cause of death worldwide among those ages 15-59 Figure 3

Challenges to Addressing the Epidemic: 

Challenges to Addressing the Epidemic Many lack basic information about HIV/AIDS Most people in low- and middle-income countries do not have access to key prevention and care services Lack of infrastructure, training, quality andamp; monitoring systems, facilities etc. may impede access; other barriers include price, patent laws and other regulatory issues; and the impact of the epidemic on the health sector and health care workers Figure 14

Challenges continued…: 

Challenges continued… Collateral effects of the epidemic (epidemic exacerbates existing problems and vice versa) There are promising research directions – microbicides, vaccines – but a vaccine is still years away Resources…$$$ Figure 15

Resource Needs to Address Epidemic in Hard Hit Countries: 

Resource Needs to Address Epidemic in Hard Hit Countries NEED andamp; AVAILABLE FUNDING UNAIDS estimates that approximately $12 billion is needed now, to effectively respond in resource poor settings, climbing to $20 billion annually by 2007 2004 global spending estimated at approximately $6.1 billion KEY INITIATIVES The Global Fund to Fight AIDS, Tuberculosis, and Malaria has received $6.0 billion in pledges through 2008* President’s Emergency Plan for AIDS Relief (PEPFAR) World Health Organization’s 3x5 Initiative *Pledges as of March 1, 2005; Sources: UNAIDS, AIDS Epidemic Update, December 2004; Global Fund, 2005; WHO.

The U.S. Government Response to the Global Epidemic: 

The U.S. Government Response to the Global Epidemic U.S. funding began in 1986; has increased significantly since 1999 PEPFAR $15 billion over 5 years (starting in FY 2004) Almost $10 billion in new money, including $1 billion for Global Fund 15 country focus Concrete goals: prevent 7 million, treat 2 million, care for 10 million Sources: White House, 2004; Kaiser Family Foundation, U.S. Government Funding for Global HIV/AIDS Through FY 2005, June 2004; Kaiser Family Foundation, Fact Sheet: Federal Funding for HIV/AIDS: The FY 2006 Budget Request, February 2005.

Key Challenges & Questions for the U.S. Response: 

Key Challenges andamp; Questions for the U.S. Response How much? How fast? Where (hard hit countries 'vs' next wave)? Bilateral vs. Multilateral (Global Fund) support 'Earmarks' based on politics or public health? Collaboration with in-country and multilateral partners? What is the U.S. 'fair share'? Figure 19

Key Challenges & Questions for the U.S. Response, cont.: 

Key Challenges andamp; Questions for the U.S. Response, cont. Where does new money come from? Short term (emergency) and long term Collateral impacts – how to address? Distributive andamp; Absorptive capacity Measures of success? Combating skepticism and apathy, showing what works How to continue addressing epidemic at home Figure 20

Important to Remember – The “Projected Future” is NOT inevitable: 

Important to Remember – The 'Projected Future' is NOT inevitable Care and treatment have reduced morbidity and mortality among people with HIV/AIDS in those countries with access Prevention success stories, including Senegal, Thailand, Uganda, Zambia, U.S. With a scaled up, global response, approximately 29 million new infections can be prevented by 2010 Figure 21
