"It has always been our intent to give the broadest possible coverage to the proceedings of this AIDS conference. Thousands of people who are passionately interested in new aspects of AIDS research, but unable to travel to the conference, will be able to participate in the meeting," said Professor Hoosen Coovadia, of the XIII International AIDS Conference. "We hope that this global sharing of knowledge will stimulate new thinking in the battle against HIV disease."

Speaking on behalf of the International Council of AIDS Service Organizations, a co-organizer of the XIII International AIDS Conference, community program chairpersons Peter Busse and Clarence Mini said, "Community- based organizations, providing care and support to millions of people living with HIV around the world, must continue initiating a broad range of crucial programs and policies to help support people living with HIV disease. The provision of information on the Internet is an additional resource for many of these groups and the people they serve. The organizers of the XIII International AIDS Conference have taken a major step forward in this effort by directly delivering conference presentations to a wider audience. Webcast.aids2000.com is a pioneering project and one that we hope will serve as a benchmark for other scientific conferences."

Certain presentations will be available for review online within hours of their initial public viewing in Durban, while remaining presentations will be available within one to two weeks of the conference. In addition, daily summaries of the entire conference will be available for review and print. The Webcast service will be available at the Internet address webcast.aids2000.com and will be operational from July 9, 2000 until December 31, 2001.

The International AIDS Conference takes place once every two years and is the largest international HIV/AIDS forum for sharing new clinical, scientific and social data. More than 10,000 delegates are expected to attend this year's meeting in Durban, including scientists, physicians and other healthcare professionals, people with HIV/AIDS, representatives of community groups and social workers.

The Webcast is made possible by the financial sponsorship of Gilead Sciences, Inc. "We are very pleased to be able to support this pioneering project," said John C. Martin, Ph.D., President and CEO of Gilead Sciences. "By providing timely worldwide access to the comprehensive information presented at the conference, the Webcast will make a significant contribution to the knowledge base of all who are involved in the global fight against HIV."
