What is World AIDS Day?

World AIDS Day - December 1 - Collective Action: Sustain and accelerate HIV progress
The World AIDS Day 2024 theme is Collective Action: Sustain and Accelerate HIV Progress

Two World Health Organization (WHO) public information officers started World AIDS Day in 1988 as an international day for global health. Since then, it has been observed each year on December 1.

World AIDS Day is a day of solidarity for people around the world who are affected by HIV and for voices to unite by sharing experiences, remembering those lost, and standing together in the fight against HIV. The observance is also reserved as a day to bridge new and effective programs and policies across different sectors around HIV/AIDS.

While great strides have been made since the first known cases of AIDS were reported in 1981, the disease remains a public health challenge. World AIDS Day is an opportunity for individuals and communities to honor the more than 32 million people worldwide who have died from AIDS-related illness.

Every year, United Nations agencies, federal agencies, and societies from across the globe join together to campaign around specific themes related to HIV. To learn more about the History of World AIDS Day and see all the previous themes, visit the UNAIDS World AIDS Day page.

The Story of HIV at CDC: Online Exhibition

This online exhibition (developed by the David J. Sencer CDC Museum in association with the Smithsonian Institution) explores CDC's early response to the HIV epidemic. The exhibit offers an over 40-year timeline documenting CDC's historic role in addressing the HIV epidemic in the United States and around the world. It also captures the personal experiences of public health experts who led the CDC investigations that shaped health care policy and saved millions of lives in the process.
