HIV/AIDS

A new report by the Joint United Nations Programme on HIV/AIDS (UNAIDS), released on World AIDS Day 2011, shows that 2011 was a game changing year for the AIDS response with unprecedented progress in science, political leadership and results. The report also shows that new HIV infections and AIDS-related deaths have fallen to the lowest levels since the peak of the epidemic. New HIV infections were reduced by 21% since 1997, and deaths from AIDS-related illnesses decreased by 21% since 2005.

According to UNAIDS and WHO estimates, 47% (6.6 million) of the estimated 14.2 million people eligible for treatment in low- and middle-income countries were accessing lifesaving antiretroviral therapy in 2010, an increase of 1.35 million since 2009. The 2011 UNAIDS World AIDS Day report also highlights that there are early signs that HIV treatment is having a significant impact on reducing the number of new HIV infections.
 
At the end of 2010 an estimated:

• 34 million [31.6 million – 35.2 million] people globally living with HIV
• 2.7 million [2.4 million – 2.9 million] new HIV infections in 2010
• 1.8 million [1.6 million – 1.9 million] people died of AIDS-related illnesses in 2010

Treatment has averted 2.5 million deaths since 1995

People living with HIV are living longer and AIDS-related deaths are declining due to the lifesaving effects of antiretroviral therapy. Globally there were an estimated 34 million people [31.6 million – 35.2 million] living with HIV in 2010, and since 2005, AIDS-related deaths decreased from 2.2 million [2.1 million – 2.5 million] to 1.8 million [1.6 million – 1.9 million] in 2010. Around 2.5 million deaths are estimated to have been averted in low- and middle-income countries due to increased access to HIV treatment since 1995.

Progress in HIV prevention

New HIV infections have been significantly reduced or have stabilized in most parts of the world. In sub-Saharan Africa the number of new HIV infections has dropped by more than 26%, from the height of the epidemic in 1997, led by a one third drop in South Africa, the country with the largest number of new HIV infections in the world.

However, the number of new HIV infections continues to rise in Eastern Europe and Central Asia, Oceania and Middle-East and North Africa, while it has remained stable in other regions of the world.

Declines in new HIV infections are also being spurred by changes in sexual behaviour, particularly in young people, as people reduce their numbers of sexual partners, increase condom use and are waiting longer before becoming sexually active. HIV prevalence declined among young people in at least 21 of 24 countries with national HIV prevalence of 1% or higher.

The report highlights that an increase in uptake of male circumcision is also starting to contribute to declines in new HIV infections. Studies show that 2000 new HIV infections were averted among men in Kenya’s Nyanza province after scale up of voluntary male circumcision.

Around 400 000 new HIV infections in children are estimated to have been averted since 1995 due to increased access to effective antiretroviral regimens in low- and middle income countries by 2010, almost half (48%) of all pregnant women living with HIV were able to access effective regimens to prevent their child from becoming infected with the virus.

At the end of 2010 around US$ 15 billion was available for the AIDS response in low- and middle-income countries. Donor funding has been reduced by 10% from US$ 7.6 billion in 2009 to US$ 6.9 billion in 2010. In a difficult economic climate the future of AIDS resourcing depends on smart investments.

To rapidly reduce new HIV infections and to save lives, the 2011 UNAIDS World AIDS Day report underscores that shared responsibility is needed.
