It said there are some signs that attitudes and policies are starting to change.

About 2.3 million children under 15 are infected with HIV, 15.2 million children under 18 have lost one or both parents to AIDS, and millions more have been made vulnerable, according to the report.

"In the year since (the programme was launched), the world's response to protect and support AIDS-affected children remains tragically insufficient. But in important and positive ways, that is beginning to change," it said.

The agencies estimate that 30 billion dollars (23 billion euros) are required to address the "four P's" of their strategy: preventing mother-to-child transmission of HIV; providing paediatric treatment; preventing infection among adolescents and young people; and protecting and supporting children affected by HIV/AIDS.

The programme is aiming to offer appropriate services to 80 percent of HIV-infected mothers by 2010, as well as antiretroviral treatment or antibiotic treatment to 80 percent of children in need.

It is targeting a 25 percent cut in the percentage of young people living with HIV within three years.

"Over the past year, there has been a broad, growing recognition of the need to intensify and accelerate action towards universal access to comprehensive prevention, treatment, care and support," the report said.

It called on more governments to follow the example of Britain, Ireland and the US President's Emergency Plan for AIDS Relief, and to earmark at least 10 percent of their AIDS funding for children and adolescents.
