What is World AIDS Day?

Two 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 page.
