In the final report from the Start Free, Stay Free, AIDS Free initiative, UNAIDS and partners* warn that progress towards ending AIDS among children, adolescents and young women has stalled and none of the targets for 2020 were met. The report shows that the total number of children on treatment declined for the first time, despite the fact that nearly 800 000 children living with HIV are not currently on treatment. It also shows that opportunities to identify infants and young children living with HIV early are being missed—more than one third of children born to mothers living with HIV were not tested. If untreated, around 50% of children living with HIV die before they reach their second birthday.
