HIV develops very rapidly among infants and children, and, without treatment, a third of infected children will die of AIDS before their first birthday, with half dying before they are two. In 2007, there were 270,000 deaths attributed to HIV in under-15s, most of which could have been prevented through early diagnosis and effective treatment. Though the number of children receiving antiretroviral therapy (ART) has increased significantly in recent years, at the end of 2007 just 200,000 of the 690,000 children needing ART were receiving it.According to non-governmental sources reporting to UNAIDS, it is estimated just 9% of countries with generalised epidemics provide paediatric HIV treatment in the areas where it is needed.The original source is at http://www.avert.org/hiv-children.htm.
