AIDS Virus May Be Weakening

The virus which causes Aids may be getting less powerful, researchers say.

A team at the Institute of Tropical Medicine, in Antwerp, compared HIV-1 samples from 1986-89 and 2002-03.

They found the newer samples appeared not to multiply as well, and were more sensitive to drugs - some other studies argue they are becoming more resistant.

The researchers, writing in the journal Aids, stressed their work in no way meant efforts to prevent the spread of HIV should be scaled down.
