2. 15 by 15: A Global Target Achieved
For the first time in global health history, in March the world has reached a global numerical treatment target prior to the agreed deadline: providing antiretroviral therapy to 15 million people by 2015.

3. Tremendous progress has been made in the process of reaching this goal

4. But we still have an epidemic

[1.4 million – 2.0 million]
The epidemic is not spread evenly around the globe
Total: 36.9 million [34.3 million – 41.4 million]

7. Global estimates for adults and children  2014
People living with HIV 36.9 million [34.3 million – 41.4 million]
New HIV infections in million [1.9 million – 2.2 million]
Deaths due to AIDS in million [ – 1.6 million]

12. About 5,600 new HIV infections a day in 2014
About 66% are in Sub Saharan Africa
About 600 are in children under 15 years of age
About 5,000 are in adults aged 15 years and older, of whom:
─ almost 48% are among women
─ about 30% are among young people (15-24)

17. Challenges
Although HIV testing capacity has increased over time, enabling more people to learn their HIV status,
nearly half of all people with HIV are still unaware they are infected.3
HIV has led to a resurgence of tuberculosis (TB), particularly in Africa, and TB is a leading cause of death for people with HIV worldwide.4, 5 In 2013, approximately 13% of new TB cases occurred in people living with HIV.6
However, between 2004 and 2014 TB deaths in people living with HIV declined by 33%, largely due to the scale up of joint HIV/TB services.

18. More Challenges
Women represent approximately half (51%) of all adults living with HIV worldwide. HIV is the leading cause of death among women of reproductive age. Gender inequalities, differential access to service, and sexual violence increase women’s vulnerability to HIV, and women, especially younger women, are biologically more susceptible to HIV.
Young people, ages 15-24, account for approximately 30% of new HIV infections (among those 15 and over).2
In sub-Saharan Africa, young women account for 63% of young people living with HIV.
Globally, there were 2.6 million children living with HIV in 2014, 220,000 new infections among children, and 150,000 AIDS deaths.

19. Sub-Saharan Africa
Sub-Saharan Africa, the hardest hit region: home to 70% of people living with HIV but only about 13% of the world’s population.1, 7
Most children with HIV live in this region (88%).2
Almost all of the region’s nations have generalized HIV epidemics— that is, their national HIV prevalence rate is greater than 1%.
In 9 countries, 10% or more of adults are estimated to be HIV-positive.
South Africa has the highest number of people living with HIV in the world (6.8 million). Swaziland has the highest prevalence rate in the world (27.7%). Recent data offer promising signs, with national HIV prevalence and/or incidence stabilizing or even declining in many countries in the region.1

20. What we do: President’s Emergency Plan for AIDS Relief (PEPFAR
Created in 2003 brought significant new attention and funding to address the global epidemic, as well as TB and malaria.11 PEPFAR authorized up to $15 billion over 5 years, primarily for bilateral programs and multilateral contributions to the Global Fund to Fight AIDS, Tuberculosis and Malaria (The Global Fund) as well as UNAIDS.
Reauthorized in 2008 and, in 2013
In FY 2015, Congress appropriated a total of $5.2 billion for bilateral HIV and $1.35 billion for the Global Fund, totaling $6.6 billion.
The President’s FY 2016 budget request for bilateral HIV programs is $5.2 billion. The Global Fund request is for $1.1 billion, which would represent a decrease of $244 million below FY 2015 levels.13

22. US Role
Today, there are multiple federal departments, agencies, and programs that address the global epidemic, and the U.S. government is the single largest donor to international HIV efforts in the world, including the largest donor to the Global Fund.13, 14

23. Global effort
International efforts to combat HIV began in the first decade of the epidemic with the creation of the WHO’s Global Programme on AIDS in UNAIDS was formed in 1996 to serve as the UN system’s coordinating body and to help galvanize worldwide attention to AIDS.
In 2000, all nations agreed to global HIV targets to halt and begin to reverse the spread of HIV by 2015, as part of the UN Millennium Development Goals (MDGs), and the World Bank launched its Multi- Country AIDS Program (MAP). As of 2015, the AIDS-related targets of MDGs were met.1

24. Next steps
The international community will soon agree upon new Sustainable Development Goals (SDGs), which include a target to end the AIDS epidemic by
On World AIDS Day 2014, UNAIDS set targets for 2020 aimed at ending the epidemic by The targets include achieving “90% of people living with HIV knowing their HIV status; 90% of people who know their HIV-positive status on treatment; and 90% of people on treatment with suppressed viral loads.”17

25. To contribute to
ending the AIDS epidemic as a public health threat by 2030, the world
must ensure that by 2020: (a) 90% of all people living with HIV know
their HIV status; (b) 90% of all people diagnosed with HIV infection
receive sustained antiretroviral therapy; and (c) 90% of all people
receiving antiretroviral therapy achieve sustained viral suppression.

27. People living with HIV accessing antiretroviral therapy
As of March 2015, 15 million people living with HIV were accessing antiretroviral therapy, up from 13.6 million in June 2014.
41% [38%-46%] of all adults living with HIV were accessing treatment in 2014, up from 23% [21%-24%] in 2010.
32% [30%-34%] of all children living with HIV were accessing treatment in 2014, up from 14% [13%-15%] in 2010.
73% [68%-79%] of pregnant women living with HIV had access to antiretroviral medicines to prevent transmission of HIV to their babies in 2014; new HIV infections among children were reduced by 58% from to 2014.

32. UNAIDS 90-90-90: HIV Treatment Targets for 2020 with Global Estimates (2014)
90% of HIV+ people diagnosed
Target 2:
90% of diagnosed people on ART
Target 3:
90% of people on ART with HIV RNA suppression
In 2014 UNAIDS set 3 ambitious targets to increase global coverage of HIV care by the year 2020
These are:
Target % of all people living with HIV to be diagnosed
Target % of those diagnosed to receive antiretroviral treatment
And Target % of all of those on treatment to achieve viral suppression
This means that in the final category, 73% of all HIV positive people should be achieving viral suppression by 2020.
The numbers here in white show how many people should be in each category, given that nearly 37 million people are estimated to be living with HIV globally.

Breakpoint 2:

Breakpoint 3:
15.3 million
Not Virally Supressed
Using the most recent data from UNAIDS, and a systematic review on viral suppression rates by Mcmahon et al, this global cascade estimates where we are currently compared to the targets.
Just over half of all HIV + people know their status and 41% (about 15 million) are on treatment as of March The numbers in white show the most current estimates for the number of people in each category worldwide.
Where the targets are not yet reached – red arrows illustrate the gaps in the cascade – This is where we are missing the targets and we will define these as breakpoints.
Can these UNAIDS target be reached? … (Pause)

37. How was 15 by 15 Achieved?
strong and sustained leadership and commitment,
community engagement,
robust funding,
increased knowledge of HIV status,
a reliable supply of effective and affordable medicines,
improved efficiency and quality of treatment services,
innovation,
progress in reducing HIV-related stigma and discrimination.

determinants of health: including poverty, hunger,
human rights, punitive laws, we will not «end» HIV/AIDS
