The biggest problem we are going to face

The biggest problem we are going to face is availability of resources," George Tembo, HIV/AIDS chief of the UN Population Fund (UNFPA), told IRIN/PlusNews. "There's a huge shortfall and we are thinking about innovative ways of financing. In as much as it is important to have donors put in more money, increasingly national governments will need to put more and more of their resources into HIV for prevention and treatment."

The total number of young people aged 15-24 living with HIV has dropped since 2001, however, from 5.7 million to 5.0 million by the end of 2009. The report attributes the decline to safer sex practices.
