Scientists report that these new generations of HIV drugs are so effective that they are very close to eradicating the virus in the infected. The latest cutting edge treatments, seem to be able to limit the effects of the disease.

Experimental therapies show that HIV genes in infected cells may be "switched off" and therefore allow sufferers to control their condition without drugs.

At the International AIDS Society conference in Sydney, a US HIV specialist Dr Joseph Eron reported that there were over 20 antiretroviral treatments on the market with the most eyes turned to a new class of drugs called integrase inhibitors. They work differently from other drugs as they block the HIV virus from infecting new cells.

Two drugs will be developed as one Raltegravir. The licensing is expected in September in US while it has already seen the light of the day in Australia. Reports show that the drug is more potent and has fewer side effects than its predecessors. This drug is supposed to work wonders for those patients who have become resistant to other treatments.

Geneticists have also thought of some new ways to fight off the disease. As HIV gets into human genes and damages the cells by producing more HIV, researchers from the City of Hope Beckman Research Institute in California found a way to turn off this HIV gene, allowing the disease to be controlled for long periods without drugs.

Such approaches have a huge potential to lead to eradication of the virus.
