A team of global scientists have launched a strategy to find cure for AIDS after a single U. S. patient named Timothy Ray Brown was cured of the disease through a miraculous treatment procedure.

Mr. Brown underwent treatment in Berlin in Germany in which his immune system was destroyed and a stem cell transplant was carried out from a donor whose genetics resists HIV infection. Doctors say that the treatment is too expensive and cannot be replicated on a large scale.

However, after years since his successful treatment in 2007, the scientists now believe that it is time to look for a cure to the disease. Since the disease surfaced 31 years ago, researchers have achieved remarkable achievements in fighting the disease.

The latest report from United Nations AIDS program (UNAIDS) has shown that the total number of AIDS-related deaths worldwide fell to 1.7 million last year from some 1.8 million in 2010. Doctors now use a combination of drugs to fight the infection but the virus can embed itself in the DNA and remain dormant. This means that the patient has to take drugs for lifetime.

"Treatment is for life, and we know that it is important today and that it can slow the spread of the virus," said Michel Sidibé, executive director of UNAIDS.
