About 2.5 million people are infected with HIV every year, according to a recent analysis of a global AIDS study.
During the past decade the rate of new infections have "stayed relatively constant" since its peak in 1997 of 3.3 million new infections per year. While the rate of annual death from HIV/AIDS has been in a steady decline from a peak of 1.8 million in 2005 to 1.2 million in 2015.
"Although scale-up of antiretroviral therapy and measures to prevent mother-to-child transmission have had a huge impact on saving lives, our new findings present a worrying picture of slow progress in reducing new HIV infections over the past 10 years," said lead author Haidong Wang.
The report, which analyzes findings of the Global Burden of Disease 2015 study, was published in the Lancet HIV Journal to coincide with the launch of the International AIDS meeting in Durban, South Africa.
According to the GBD 2015 study, 75 percent of the new HIV infections occurred in sub-Saharan Africa, while south Asia accounted for 8.5 percent and southeast Asia for 4.7 percent.
It says that in southern Africa, more than one percent of the populations of Botswana, Lesotho and Swaziland were becoming infected with HIV. In Europe, Russia and Ukraine had the highest rates, while Cambodia had the highest rates in Asia.
Between 2005 and 2015 the use of antiretrovirals has increased from 6.4 percent to 38.6 percent for men and from 3.3 percent to 42.4 percent for women.
Despite those increases, the study says most countries fall short of the UNAIDS target calling for countries to ensure that 81 percent of people living with HIV/AIDS are receiving ART by 2020. Although, according to report, no country has met that goal, Sweden, the United States, Netherlands and Argentina are all close at about 70 percent
