Almost three in five people infected with HIV, or 21.7 million globally, took antiretroviral therapy (ART) in 2017 -- a new record for anti-AIDS drug access, the UN's HIV/AIDS agency said Wednesday.

There were 36.9 million people living with the immune system-attacking virus in 2017, of whom 15.2 million were not getting the drugs they need, UNAIDS reported.
