US 'committed to Aids funding'

The US is the world's biggest donor to Aids programmes, but there are concerns about future funding if the Republican Party candidate Donald Trump becomes president.

Campaigners at the UN Aids Conference in the South African city of Durban worry that the social conservative policies of the Republican nominee and his running mate, Mike Pence, might alienate minorities, including the gay community.

But Deborah Birx, global Aids co-ordinator at US Department of State appointed by the Democratic Party, has soothed fears that a Trump presidency would dramatically slash global Aids funding.

She acknowledged there was already a $7bn (£5.3bn) funding gap, but told the BBC's Karen Allen how it could be addressed.
