World AIDS Day was first conceived in August 1987 by James W. Bunn and Thomas Netter, two public information officers for the Global Programme on AIDS at the World Health Organization (WHO)in Geneva, Switzerland.
Government and health officials, non-governmental organizations and individuals around the world observe the day, often with education on AIDS prevention and control.
World AIDS Day is one of the eight official Global Public Health Campaigns marked by the World Health Organization (WHO)
Each World AIDS Day campaign focuses on a specific theme, chosen following consultations with UNAIDS,WHO and a large number of grassroots, national and international agencies involved in the prevention and treatment of HIV/AIDS.
As of 2013, AIDS has killed more than 36 million people worldwide (1981-2012), and an estimated 35.3 million people are living with HIV,making it one of the most important Global Public Health issues in recorded in history
