Today's throwback goes to the 30th of May, 2006 where the incidence of new HIV infections appeared to have stabilized for the first time in 25 years of AIDS.

The world had been making progress against the disease, which brought about better access to drugs and the growth in the awareness of the epidemic. But the United Nation’s agency warned that there were still bigger problems to deal with in coordinating the fight against the disease.

Fast-forward to today, a new study released by the University of Washington's Institute for Health Metrics and Evaluation estimated that 5.3 million South Africans under the age of 50 are HIV-positive, a five percentage point increase from 2000. Some are of the view that this is a good sign, it means those infected with HIV are living longer.
