You are invited to join the South African Centre for Epidemiological Modelling and Analysis (SACEMA) for a discussion on the role of mathematical models in reducing the rate of HIV-related mortality and the rate of new infections on World Aids Day, 1 December 2016. The lecture forms part of the NRF Science for Society lecture series and will be broadcast live via SAfm. Background: While Southern Africa continues to bear the brunt of the HIV pandemic, the rate of occurrence of new HIV infections in adults has fallen steadily from 2.5% p.a. in 1998 to 0.6% p.a. in 2016. AIDS-related mortality has dropped from 1.3% in 2008 to 0.4% p.a. in 2016. This Science for Society Lecture will look at how mathematical models play a critical role in helping reduce HIV-related mortality and the rate of new infections, and how clinical studies within South Africa are helping revolutionise treatment and prevention. The lecture will be broadcast live on SAfm and will be video streamed. The speakers are Prof. John Hargrove, senior research fellow and founding director of SACEMA at Stellenbosch University. Dr Gert van Zyl is virological pathologist at the National Health Laboratory Service in Tygerberg and an associate professor at SU. Refreshments will be served from 18:00-18:45 For more information: Lynnemore Scheepers Research Manager DST-NRF Centre of Excellence in Epidemiological Modelling and Analysis (SACEMA) Stellenbosch University 19 Jonkershoek Road Stellenbosch 7600 Tel: +27 21 808 2589; Fax: +27 21 8082586 Website: http://www.sacema.org Epidemiological update: http://www.sacemaquarterly.com
