Coinciding with the International AIDS Conference hosted this week in Vienna, PLoS Medicine has published three articles on HIV testing and prevention.

Bertrand Auvert and colleagues describe the large-scale roll-out of adult male circumcision through a program in South Africa, investigating the feasibility of the UNAIDS/WHO operational guidelines for targeted African settings.

Scott Kellerman and Shaffiq Essajee argue that the time has come to increase access to HIV testing for children, especially in sub-Saharan Africa.

Younsook Lim and colleagues describe the Rwanda Learning Collaborative on Child Health, which aimed to improve and extend the impact of prevention of mother-to-child transmission of HIV/AIDS.
