Researchers warn of no quick HIV cure

DURBAN, South Africa: Researchers on Tuesday praised progress made towards developing an HIV cure, but said it was impossible to tell when or even if a cure for the devastating epidemic would be found.

Some 18,000 delegates from around the world have converged on the coastal city of Durban for the 21st International Aids Conference where the latest advances in research are being presented.

Last week, scientists unveiled an aggressive strategy to develop an outright cure, but many of those in Durban warned it was still a young field of research.

"A true cure is an aspirational goal," said principal author of the strategy Professor Sharon Lewin.

She said remission -- the ability of a patient to stop taking anti-retroviral treatment and remain healthy -- was the intermediate goal.

"We don’t know when we will have a cure and if we will have a cure," said Nobel Medicine laureate Francoise Barre-Sinoussi, who in 1983 helped identify the human immunodeficiency virus (HIV) that causes Aids.

"We really believe that we will be able to have sustainable remission," she said.

"That’s not to say a cure is impossible, it’s just to say to have a real cure is very, very hard." In 2004, Aids deaths peaked at more than two million.

Last year, the toll was around 1.2 million lives -- a decline attributed in large part to the success of anti-retroviral drugs, which reduce the symptoms of people carrying the virus.
