Sir Elton John and Stephen Lewis, the United Nations special envoy for HIV/Aids in Africa, are to be honoured by The International Association of Physicians in Aids Care at the organisation's sixth annual 'Honouring Our Heroes' ceremony in Chicago on September 15.

The organisation will also honour Sister Mary Elizabeth of the Aids Education Global Information System, widely regarded as the world's most important on-line source of HIV/Aids information.

Lewis and Clark will share IAPAC's annual Jonathan Mann Health Human Rights Award. Sir Elton is due to receive the 2003 Dag Hammarskjold Award, whose former recipients include Bill Clinton and Desmond Tutu.

IAPAC's 'Honouring Our Heroes' event will coincide with the 43rd Interscience Conference on Antimicrobial Agents and Chemotherapy.
