A study funded by the U.S. National Institutes of Health tracked black gay and bisexual men in six cities, and found the rate of new infections is 2.8 per cent a year. That's 50 per cent higher than is seen in white men who have sex with men.
Worse, among those 30 and younger, nearly 6 per cent a year were becoming infected. The authors said those rates rival some parts of sub-Saharan Africa.
The study didn't measure national prevalence of HIV in this population, but the government has long called HIV among young black gay men alarming.
