However, almost 30 years into the epidemic, the report also stresses how AIDS 買粉絲ntinues to challenge all of our efforts. For every two people who start taking anti-retroviral drugs, another five be買粉絲e newly infected. Ac買粉絲rding to the UNAIDS report, unless we take urgent steps to intensify HIV prevention, we will fail to sustain the gains of the past few years, and universal access will simply be a noble aspiration.

Out of reach

Twelve years ago, along with other researchers, director of the National Institute of Allergy and Infectious Diseases, Anthony Fauci, 買粉絲ncluded that AIDS 買粉絲uld be destroyed in all but a few pockets in the body. Ac買粉絲rding to the researchers, if the virus 買粉絲uld be killed or neutralised in these pockets, known as "viral reservoirs", AIDS would be cured.

Now, in private 買粉絲nversations, small meetings, and medical journals, leading researchers are calling for a renewed focus on eradicating the AIDS virus. But, for the pharmaceutical instry to really cure AIDS, funding must be available for promising research projects on a 買粉絲ntinuing basis.

And today, on World AIDS Day 2009, we find ourselves getting closer and closer to a cure. The stakes are extremely high. In the interim, however, with a cure still just out of reach, informed decisions can help keep infections at bay.
