UNAIDS has just published its latest Gap Report, which provides global HIV/AIDS stats and outlines key issues that still need to be addressed to end the epidemic, according to a new release from the organization.

The latest stats, taken from 82 countries, estimate that currently, 35 million people are living with HIV around the world, with 2.1 million people newly infected in 2013. New HIV infections have dropped by 38 percent since 2001, with a 13 percent global decline over the past three years alone.

However, it is estimated that nearly 19 million people living with HIV worldwide do not know their status. Health officials also report that about 22 million people living with HIV around the world still do not have access to lifesaving treatment.

At-risk groups highlighted in the report included adolescent girls and young women in Africa, who account for one in four new HIV infections in the region, as well as prisoners, female sex workers and people who inject drugs. Barriers to ending the epidemic identified by UNAIDS included the criminalization of same-sex acts, which occurs in 78 countries worldwide, as well as HIV criminalization—including specific non-disclosure, exposure and transmission laws—which exists in 42 countries.
