On World AIDS Day WHO emphasizes that expanding antiretroviral therapy to all
people living with HIV is key to ending the AIDS epidemic within a generation.
"The Millennium Development Goal of reversing the HIV epidemic was reached
ahead of the 2015 deadline - an incredible achievement that testifies to the
power of national action and international solidarity," declared WHO
Director-General, Margaret Chan.
Expansion of antiretroviral therapy (ART) has resulted in a stark reduction of
At the same time, increasingly effective prevention efforts have reduced
numbers of new HIV infections. Since the epidemic's peak in 2004, the number of
- deaths has fallen by 42% with some 7.8 million lives being saved over the
last 15 years, according to a new WHO report. The number of new infections has
fallen by 35% since the turn of the century.
Over the last 15 years, scale-up of ART has been most dramatic in the WHO
African Region where now more than 11 million people are receiving HIV
treatment, up from 11 000 at the turn of the century. People living with HIV in
Africa are now more likely to receive treatment than people living in most
other parts of the world. Globally, in June 2015 close to 16 million people out
of a total of 37 million people living with HIV were taking ART.
Doubling access to testing and antiretroviral therapy
At the UN General Assembly in September, world leaders endorsed a new set of
Sustainable Development Goals and milestones, including a call for ending the
AIDS epidemic by 2030. Reducing the number of new infections by 75% and
doubling the number of people on ART by 2020 are the first milestones towards
achieving this goal.
Trial results published earlier this year have confirmed that people living
with HIV who begin antiretroviral therapy soon after acquiring the virus -
before the virus has weakened their immune systems - are more likely to stay
healthy and less likely to transmit the virus to their partners. Those findings
led WHO in September to recommend that everyone living with HIV be offered
In the effort to help countries implement the "treat all" recommendation, WHO
is now presenting an additional set of recommendations on how to expand ART to
all - in a rapid, focused, and efficient manner.
These recommendations include using innovative testing approaches such as
community or self-testing to help increase the number of people who know their
HIV status; starting treatment faster in those people who are diagnosed with
HIV; bringing ART to the community; and allowing for greater intervals between
clinic visits for people who have been stable on ART for some time. They also
highlight the importance of improving access to viral load testing and new
classes of antiretroviral drugs.
"WHO applauds governments, civil society, and organizations that have made
availability of life-saving antiretroviral therapy possible in the most trying
circumstances. The new recommendation to expand ART to all people living with
HIV is a call to further step up the pace," said Dr Winnie Mpanju-Shumbusho,
Assistant Director General at WHO.
Preventing new infections
Reducing the number of new HIV infections remains a major focus for the vision
of ending AIDS. There is increasing concern about a slow down-or even reversal
- in the decrease of new infections in some countries and among some of the
most affected population groups. "We must deploy all means to strengthen the
HIV prevention response. The health sector can and must play a central role,"
added Dr Mpanju -Shumbusho
Already, over the last 5 years in Africa some 10 million men have undergone
voluntary medical circumcision, a procedure that reduces their risk of
acquiring HIV by 60%. New approaches to prevention are also emerging, including
the use of antiretroviral drugs to help people at substantial risk from
acquiring HIV. WHO now recommends this practice, called "pre-exposure
prophylaxis," or PrEP, as an additional option to augment comprehensive
prevention for people at heightened risk of HIV infection. Other elements of
this package include behaviour-change communication, the consistent use of male
and female condoms and prevention programmes for key populations, including
harm reduction for people who use drugs.
The same drugs that keep people living with HIV from becoming sick also prevent
transmission of the virus from pregnant women to their infants. Among the 22
countries that account for 90% of new HIV infections, 8 have reduced new
infections among children by more than 50% since 2009, based on 2013 data, and
another 4 are close to that mark.
Ingredients of success
Some low- and middle-income countries have made remarkable progress towards
universal access to HIV services: 12 countries have ensured that 60% or more of
all people living with HIV are aware of their infection and receiving
antiretroviral therapy. Key ingredients of the successful HIV response in these
countries are national ownership, greater focus of HIV services to reach the
most affected locations and populations based on good data, and simplification
of prevention and treatment services.
"The sense of urgency that was the norm during the disease's most-destructive
years must not be allowed to abate," Dr Mpanju-Shumbusho said. "HIV remains a
major health challenge - drawing sharp attention to health system weaknesses
and gaps in universal health coverage. Addressing these issues will be critical
to meeting the new global targets for AIDS."
