HIV/AIDS: A Global Epidemic
The HIV/AIDS epidemic remains a global health challenge of unprecedented dimensions and a monumental threat to development progress.
Exacting a High Price in Developing Countries
There are 38 million people living with HIV/AIDS around the world, the vast majority in developing countries and more than half are women.1
Sub-Saharan Africa continues to disproportionately bear the global HIV/AIDS burden. Over 58% of all new adult HIV infections and two-thirds of AIDS-related deaths among adults occur in the region.1
Preventing the Spread of HIV/AIDS
The global response to the epidemic continues to be challenged by new infections, even with scale-up of antiretroviral treatment in low- and middle-income countries. According to UNAIDS, 3.5 million more infections occurred between 2015 and 2020 than if UNAIDS targets had been met.2
Women also continue to be disproportionately affected. Every day, more than 1,800 women acquire HIV worldwide,1 and 63% of all new HIV infections in sub-Saharan Africa are among women and girls.3
