Access to treatment has helped avert 2.5 million deaths in low and middle income countries, says the World Aids Day Report 2011 by UNAIDS. The report offers detailed regional analysis and suggests faster, smarter and better ways to minimise HIV/AIDS deaths.

2011 World AIDS Day Report

Published by: UNAIDS, November 2011


At the end of 2010, an estimated 34 million people [31.6 million–35.2 million] were living with HIV worldwide, up 17% from 2001. This reflects the continued large number of new HIV infections and a significant expansion of access to antiretroviral therapy, which has helped reduce AIDS-related deaths, especially in more recent years.

A total of 2.5 million deaths have been averted in low- and middle-income countries since 1995 due to antiretroviral therapy being introduced, according to new calculations by UNAIDS. Much of that success has come in the past two years when rapid scale-up of access to treatment occurred; in 2010 alone, 700 000 AIDS related deaths were averted.

The number of people becoming infected with HIV is continuing to fall, in some countries more rapidly than others. HIV incidence has fallen in 33 countries, 22 of them in sub-Saharan Africa, the region most affected by the AIDS epidemic.

Sub-Saharan Africa

Sub-Saharan Africa remains the region most heavily affected by HIV. In 2010, about 68% of all people living with HIV resided in sub-Saharan Africa, a region with only 12% of the global population. Sub-Saharan Africa also accounted for 70% of new HIV infections in 2010, although there was a notable decline in the regional rate of new infections. Almost half of the deaths from AIDS-related illnesses in 2010 occurred in southern Africa.


The Caribbean has the second highest regional HIV prevalence after sub- Saharan Africa, although the epidemic has slowed considerably since the mid-1990s.


Although the rate of HIV prevalence is substantially lower in Asia than in some other regions, the absolute size of the Asian population means it is the second largest grouping of people living with HIV.

In South and South-East Asia, the estimated 270 000 [230 000–340 000] new HIV infections in 2010 was 40% less than at the epidemic’s peak in 1996. In India, the country with the largest number of people living with HIV in the region, new HIV infections fell by 56%.

Eastern Europe and Central Asia

In Eastern Europe and Central Asia, there was a 250% increase in the number of people living with HIV from 2001 to 2010. There is little indication that the epidemic has stabilised in the region, with new HIV infections and AIDS-related deaths continuing to increase.

For a faster change

Accelerating the epidemic’s decline

The unparalleled global response of the past decade has already forced the epidemic into decline.

  • Behaviour change is averting g new HIV infections, especially among young people
  • Acceleration through a focus on people at higher risk of HIV infection
  • Antiretroviral treatment is key to faster progress
  • Access to treatment boosts the success of combination HIV prevention programmes
  • Accelerating the decline in tuberculosis deaths

Basic programme activities

The Investment Framework calls for the rational allocation of resources to six basic programme activities that are required to deliver substantial and sustainable progress in the HIV response:

1. Focused interventions for key populations at higher risk (particularly sexworkers and their clients, men who have sex with men, and people whoinject drugs);

2. Elimination of new HIV infections among children;

3. Behaviour change programmes;4. Condom promotion and distribution;

5. Treatment, care and support for people living with HIV;

6. Voluntary medical male circumcision in countries with high HIVprevalence and low rates of circumcision.
