GENEVA — The World Health Organization raised its estimate of worldwide AIDS cases by 50% today and said finding a vaccine may take longer than experts had thought.
In material distributed for a two-day conference on the deadly AIDS virus, the organization estimated that as many as 150,000 people have contracted the disease.
A March WHO report estimated 100,000 people had contracted acquired immune deficiency syndrome. More than 62,500 cases of AIDS from 127 countries have been reported to the organization.
Halfdan Mahler, the organization's director general, painted a bleak picture at the start of the conference on AIDS, which destroys the body's ability to fend off disease.
