This report from the Joint United Nations Programme on HIV/AIDS (UNAIDS) documents reductions in new HIV infections of 52 percent among children and 33 percent among adults and children combined from 2001 to 2012. The report’s update on the progress of voluntary medical male circumcision (VMMC) programmes in 16 countries (see pp. 18-20, PDF, 68 KB) shows that the cumulative number of men circumcised through 14 of these programmes doubled in 2012, from 1.5 million in December 2011 to 3.2 million in December 2012. It notes, however, that a dramatic acceleration in uptake is needed to circumcise 20 million men across eastern and southern Africa in five years, which would avert an estimated one in five HIV infections by 2025. The report includes a description of the rapid scale-up of VMMC services in Tanzania and a graph showing the annual number of medical male circumcisions by country, 2009-2012 (GIF, 33KB). The graph appeared in an Economist article about the report on 23 September 2013.
