||Sub-Saharan Africa bears the greatest global burden of human immunodeficiency virus (HIV) infection; 70% (25.0 million) of all persons living with HIV reside in this region. Voluntary medical male circumcision (VMMC) has been shown to reduce the risk for heterosexually acquired HIV among men by approximately 60% in three randomized controlled trials. Further studies found that the protection from HIV acquisition conferred by VMMC was sustained for 6 years following surgery. In 2007, the World Health Organization (WHO) and Joint United Nations Programme on HIV/AIDS (UNAIDS) recommended that 14 countries with generalized HIV epidemics (i.e., where >1% of the population is HIV-positive) and low male circumcision prevalence prioritize scale-up of VMMC for HIV prevention. On December 1, 2011 (World AIDS Day), funding through the President's Emergency Plan for AIDS Relief (PEPFAR) was announced to support >4.7 million VMMCs over the next 2 years. This report presents the results of VMMC scale-up in nine countries where national ministries of health and CDC are implementing VMMC services for HIV prevention: Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Tanzania, Uganda, and Zambia. During October 2009-September 2012, a total of 1,924,792 VMMCs were performed in 14 countries using PEPFAR funding provided through U.S. government agencies; of this total, 1,020,424 were conducted at approximately 1,600 CDC-supported VMMC sites: 137,096 VMMCs in 2010, 347,724 in 2011, and 535,604 in 2012. Continued program monitoring and quality assurance activities are required to ensure that CDC-supported country programs meet World AIDS Day targets for VMMC.
