facts on HIV and 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 onward transmission of HIV.

At the end of 2012, close to 10 million people were receiving ART in low- and middle-income countries. However, almost 19 million other people who are eligible for ART under new 2013 guidelines do not have access to antiretroviral drugs.

But progress has been made. In 2012, 62% of pregnant women living with HIV received the most effective drug regimens (as recommended by WHO) to prevent mother-to-child transmission of the virus.

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.
