More than 20,000 new cases of AIDS have been reported this year and those figures are expected to double by next year, Surgeon General C. Everett Koop told a capacity crowd of 700 people at the Kennedy School of Government last night.

The government official, who last October published at controversial report on AIDS at President Reagan's request, has stressed that the government should support sex education and public awareness about the disease.

"We decided to focus on informing young people about the risks of AIDS. Their sexual activity will determine whether our society will survive this devastating disease," Koop said last night at the Institute of Politics (IOP) forum.

Harvard's approach to AIDS also centers on education, said Vice President and General Counsel Daniel Steiner '54 after the speech. There have been a total of six known cases of AIDS at Harvard, according to Steiner, and a small group of central administrators and health officials was formed three years ago to coordinate University policy on the issue.

Following Koop's remarks, a Boston Globe editor who has written extensively on the AIDS crisis commented on the scope of the problem and criticized the Reagan Administration for responding inadequately to the public health issues involved.

"The whole problem is not whether we tell the kiddies or not," said deputy editorial page editor Loretta McLaughlin, "the problem is that the disease spreads."
