HIV models to inform health policyStover, JohnCurrent Opinion in HIV & AIDS: March 2011 - Volume 6 - Issue 2 - p 108–113 doi: 10.1097/COH.0b013e328343ac05 Epidemic modelling: Edited by Geoffrey Garnett and David P. Wilson Abstract Author Information Purpose of review: To review the recent use of mathematical modeling to inform decision making in HIV policy and programs. Recent findings: New mathematical modeling studies have provided information for policy and program development regarding male circumcision, the role of antiretroviral therapy in the prevention of new HIV infection, and the potential contribution of new prevention technologies such as pre-exposure prophylaxis and HIV vaccines. Summary: Several modeling studies published recently intend to provide information to decision makers to support the development of policies and strategies. These models include a study on male circumcision that provides a consensus among modeling groups on key issues relating to impact and targeting, a study proposing a new approach to treatment and prevention and explorations of the potential impacts of two new technologies (pre-exposure prophylaxis and HIV vaccines) and the conditions under which they will be most beneficial.
