10 facts on HIV/AIDS
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 transmission of HIV in couples, from a partner infected with HIV to his or her sexual partner.
At the end of 2011, over 8 million people were receiving ART in low- and middle-income countries. However, over 7 million other people who are eligible for ART still have no access to treatment.
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.
