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 nearly 37 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. Seventy percent of all people newly infected with HIV live in that region, and nearly two-thirds of all AIDS deaths occur there.1

Preventing the Spread of HIV/AIDS

The global response to the epidemic continues to be challenged by new infections, even with a more than 20-fold increase in antiretroviral treatment made available in low- and middle-income countries from 2003-2012. In sub-Saharan Africa, for every HIV-positive person placed on ARV therapy, one more is newly infected.

Women also continue to be disproportionately affected. Every day, nearly 2,400 women are infected with HIV,1 and young women ages 15-24 are twice as likely to be infected as young men of the same age.2
