The improved treatment of patients who are suffering with HIV has contributed to a large reduction in the number of people dying from the disease.
Figures from the Aids charity Avert found that during the last five years the number of deaths attributed to the virus has decreased by 21 per cent.
A spokeswoman for the organisation stated that the infection rate is also falling, as since 2001 the amount of people diagnosed worldwide has decreased by 15 per cent.
"Overall, the prospects for those living with the virus have improved greatly as a result of increased access to treatment and new scientific breakthroughs," she said.
Much of the success is down to the fact that many more sufferers now have access to the drugs.
In the UK, an estimated 86,500 people had been infected by the virus at the end of 2009. Of these around 25 per cent were unaware they were affected, according to Avert.
