"We seem to have come full circle and now have to face what will certainly be an uncomfortable truth for many of us working in the sector: we have made very little, if any progress, in getting prevention and treatment to those groups of people most vulnerable to HIV/Aids, wherever they are.

These groups people who inject drugs, transgender people and men who have sex with men. They make up the majority of those affected by the epidemic, except in sub-Saharan Africa, where they also make up an increasing share of infections in urban settings.

New obstacles
Against a backdrop of some truly extraordinary responses to the global HIV/AIDS epidemic over the past 30 years, it is both painful but necessary to acknowledge that the response for these groups remains so often a story of indifference and neglect.

Indeed we can compare our failure to adequately address these issues to the situation that prevailed in 2000.

At that time, effective HIV drugs had been available in rich countries for years, but were inaccessible in developing and emerging economies because of cost.

Today, cost is not the primary obstacle: we have drugs and we have proven interventions.

Rather, it is economic, social and political obstacles that prevent them from being made available to those who need them most."

"One can draw upon an almost infinite supply of statistics that tell the true picture for those most affected by the epidemic: in low- and middle-income countries, men who have sex with men and female sex workers are 19 and 13 times more likely to have HIV, respectively, than the rest of the population.

Men who have sex with men alone account for more than 33% of new infections in China, and projections indicate that this group could make up half or more of all new infections in Asia by 2020."
