Has the world turned its back on the HIV/Aids crisis? Current funding priorities have changed for many countries during tougher economic times and contributions to the global Aids fund have suffered as a result.

At the same time, HIV infection rates are rising rapidly in many parts of the world, especially in Eastern Europe, where infection rates have risen about 700 per cent over the past four years.

On Thursday's Riz Khan we ask: What more should be done to stem the tide against the global HIV/Aids epidemic?

We speak to Michel Sidibe, the executive director of UNAIDS, and an under secretary-general of the United Nations.

This episode of the Riz Khan show aired on Thursday, September 23, 2010.
