Data published in the UNAIDS World AIDS Day Report 2011 show that:

  • An estimated 34 million (between 31.6 million and 35.2 million) people were living with HIV worldwide at the end of 2010 – up 17% over 2001.
  • In 2010, 2.7 million (between 2.4 million and 2.9 million) people were newly infected with HIV - this is about 21% less than the annual number of new infections at the peak of the epidemic in 1997.
  • The number of people dying of AIDS-related causes fell to 1.8 million [1.6 million–1.9 million] in 2010, down from a peak of 2.2 million in the mid-2000s.
  • A total of 2.5 million deaths have been averted in low- and middle-income countries since 1995 due to antiretroviral therapy being introduced.
  • The proportion of women living with HIV has remained stable at 50% globally, although women are more affected in sub-Saharan Africa (59% of all people living with HIV) and the Caribbean (53%).
  • An estimated 6.6 million people are now receiving antiretroviral treatment in low- and middle-income countries, covering nearly half of those who are eligible for treatment.
  • Eliminating new HIV infections in children is within our grasp. In 2010, nearly 50 percent of pregnant women living with HIV received antiretroviral therapy to prevent transmitting the virus to their child.
