ABSTRACT

The latest statistics on the global HIV (http://www.avert.org/hiv.htm) and AIDS (http://www.avert.org/aids.htm) epidemic, reported that 24,296 people were diagnosed with HIV in Western Europe in 2008 (http://www.avert.org/worldstats. htm). Of these, 35 percent were men who had sex with men (http://www.avert. org/men-sex-men.htm; thereafter called MSM), suggesting that gay men remain the largest subgroup of HIV-infected individuals in Western Europe (http://www. avert.org/hiv-aids-europe.htm).
