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 38million people living with HIV/AIDS around the world, the vast majority in developing countries and more than halfare women.1

Sub-Saharan Africa continues to disproportionately bear the global HIV/AIDS burden. Over 58%of all new adult HIV infectionsand 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 treatmentin 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 Africaare among women and girls.3
