HIV – A Global Situation Update

  • HIV continues to be a major global public health issue, having claimed more than 34 million lives so far. In 2014, 1.2 [1.0–1.5] million people died from HIV-related causes globally.
  • There were approximately 36.9 [34.3–41.4] million people living with HIV at the end of 2014 with 2.0 [1.9–2.2] million people becoming newly infected with HIV in 2014 globally.
  • Sub-Saharan Africa is the most affected region, with 25.8 [24.0–28.7] million people living with HIV in 2014. Also sub-Saharan Africa accounts for almost 70% of the global total of new HIV infections.
  • HIV infection is often diagnosed through rapid diagnostic tests (RDTs), which detect the presence or absence of HIV antibodies. Most often these tests provide same day test results; essential for same day diagnosis and early treatment and care.
  • There is no cure for HIV infection. However, effective treatment with antiretroviral (ARV) drugs can control the virus so that people with HIV can enjoy healthy and productive lives.
  • It is estimated that currently only 51% of people with HIV know their status. In 2014, approximately 150 million children and adults in 129 low- and middle-income countries received HIV testing services.
  • In 2014, 14.9 million people living with HIV were receiving antiretroviral therapy (ART) globally, of which 13.5 million were receiving ART in low- and middle-income countries. The 14.9 million people on ART represent 40% [37–45%] of people living with HIV globally.
