World AIDS Day 2011

World AIDS Day is dedicated to raising awareness of the AIDS pandemic caused by the spread of HIV infection. AIDS has killed more than 25 million people between 1981 and 2007 and an estimated 33.2 million people worldwide live with HIV (as of 2007), making it one of the most destructive epidemics in recorded history. Yet today, there is serious talk about the "end" of this global epidemic. There are now 6.6 million people on life-saving AIDS medicine, but still too many are being infected. New research proves that early antiretroviral treatment will slash the rate of new HIV cases by up to 60 percent. This is described as the tipping point that so many have tirelessly tried to reach. -- Paula Nelson (30 photos total)Indian school children form a red ribbon, the universal symbol of awareness and support for those living with HIV, in Ahmadabad, India, Dec. 1, 2011.
