Size matters: the number of prostitutes and the global HIV/AIDS pandemic

Article by Talbott, J. R. in PLoS ONE 2(6): e543.doi: 10.1371/journal.pone.0000543. He argues that cross country regression data does not support the theory that male circumcision is the key to slowing the AIDS epidemic. Rather, it is the number of infected prostitutes in a country that is highly significant in explaining HIV prevalence levels across countries.
