Situation and trends
Since the beginning of the epidemic, about 34 million people have died of HIV-related causes.
Globally, 36.9 million [34.4–41.4 million] people were living with HIV at the end of 2014, but almost half (46%) of them did not know their HIV status. An estimated 0.8% of adults aged 15–49 years worldwide are living with HIV, although the burden of the epidemic continues to vary considerably between countries and regions. Sub-Saharan Africa remains most severely affected, with nearly 1 in every 20 adults living (4.8%) with HIV and accounting for nearly 70% of the people living with HIV worldwide.
