Ten years ago, health experts pledged to give people living with HIV in resource-poor countries greater access to life-saving anti-retroviral treatment by 2005.

Although nearly 10 million people now receive anti retroviral treatment which suppresses the HIV virus, challenges remain in preventing infections in adolescents.
