1 December 2008 marks the 20th anniversary of World AIDS Day. In 1988, the World Health Organization (WHO) declared the first World AIDS Day in an effort to raise public awareness about HIV/AIDS issues, including the need for support and understanding for people living with HIV/AIDS. The day is also an opportunity to highlight the need for continued development of education and prevention initiatives. Over the past 20 years, World AIDS Day has been established as one of the world’s most successful commemorative days. It is now recognised and observed by millions of people in more than 190 countries around the globe.
