10 facts on HIV/AIDS
Updated July 2015
HIV/AIDS remains one of the world's most significant public health challenges, particularly in low- and middle-income countries.
As a result of recent advances in access to antiretroviral therapy (ART), HIV-positive people now live longer and healthier lives. In addition, it has been confirmed that ART prevents onward transmission of HIV.
At the end of 2014, 14.9 million people were receiving ART worldwide; this represents 40% [37–45%] of the 36.9 million [34.3–41.4 million] people living with HIV.
Progress has also been made in preventing and eliminating mother-to-child transmission and keeping mothers alive. In 2014, a little over 7 out of 10 pregnant women living with HIV, or 1 070 000 women, received antiretrovirals (ARVs).
WHO has released a set of normative guidelines and provides support to countries in formulating and implementing policies and programmes to improve and scale up HIV prevention, treatment, care and support services for all people in need.
