WHO

HIV/AIDS remains one of the world's most significant public health challenges, particularly in low- and middle-income countries.

Thanks to recent advances in access to antiretroviral therapy (ART), HIV-positive people now live longer and healthier lives. At the end of 2009, 5.2 million people in low- and middle-income countries received ART. However, approximately 10 million people in need of ART still have no access to treatment.

WHO works with Member States to help them scale-up and deliver comprehensive services in order to mitigate the spread of the disease and lessen its effects.

This fact file provides current data on the disease, and ways to prevent and treat it.
