“…Although it remains unclear to what extent the lessons from these case studies can be extrapolated across all mobile populations, they are, with some exceptions (Thomas, Haour-Knipe, & Aggleton, 2010) generally accepted. Beyond these well-known case studies, further investigation of the relationship between migration/mobility and HIV risk tests for statistically significant differences in HIV prevalence or sexual risk behaviours (or both) between 'non-mobile' and 'mobile' groups (Coffee et al, 2005;Khan et al, 2008;Kishamawe et al, 2006;Lagarde et al, 2003;Lydie et al, 2004;Mmbaga et al, 2008;Vissers et al, 2008). However, evidence from these studies is inconclusive, inconsistent, and in some cases contradictory, with no universal correlation between mobility and HIV risk for men or women (Deane, Parkhurst & Johnston 2010).…”
