  • MSM are the most affected risk group for HIV infection in the majority of developed countries
  • HIV notifications are increasing in this group in some countries, including the US, mainly due to increased risk behavior[Sullivan 2009; Crepaz 2009; CDC 2012a]
  • Risk behavior in MSM appears to be associated with use of methamphetamines (“crystal meth”), amyl nitrite (“poppers”), and cocaine[Colfax 2005]
