The United Kingdom’s latest HIV figures reveal that while new HIV diagnoses have decreased from 7,660 to 7,370 from 2007 to 2008, the number of HIV cases among men who have sex with men (MSM) remains high, BBC News reports.

Recent estimates from the country’s Health Protection Agency show that four in 10 HIV diagnoses reported last year were among MSM—which is double the number of a decade ago. The report also showed that a fifth of HIV-positive MSM were diagnosed late in their infection, increasing their risk of death within in a year. Roughly one in 20 MSM in the U.K. are HIV positive.

“If that proportion of the general U.K. population had HIV, it would be headline news,” says Deborah Jack, chief executive of the National AIDS Trust.
