Antiretroviral therapy
Standard antiretroviral therapy (ART) consists of the use of at least three antiretroviral (ARV) drugs to maximally suppress the HIV virus and stop the progression of HIV disease. Huge reductions have been seen in rates of death and suffering when use is made of a potent antiretroviral regimen.
In 2009, an estimated 33.3 million people were living with HIV, of whom more than 30 million were living in low- and middle-income countries.
WHO and UNAIDS estimate that at least 14.6 million people were in need of antiretroviral therapy in 2009. As of the end of 2009, 5.25 million people had access to antiretroviral therapy in low- and middle-income countries.
WHO is providing countries with ongoing guidance, tools and support in delivering and scaling up antiretroviral therapy within a public health approach.
