Models of HIV and TB are well established and it is tempting to model the combination of HIV and TB by repeating a suitable TB model a number of times corresponding to the various states of HIV. This can, however, lead to a very complex model with tens, if not hundreds of parameters, requiring considerable computing power to run. Fortunately, the time scales over which the two infections progress are very different, allowing us to greatly simplify the problem.
These short courses will take place at SACEMA, Stellenbosch: Introduction to R: Management, Exploration, and Communication of Data (2-6 July 2018) and Advanced Epidemiological Methods (30 July-2 August 2018).
The Conference theme: “STEP UP – Let’s embrace all to end TB!” provides a unique opportunity to reflect on what we have done across the entire spectrum of our programmes in response to TB, what has been effective and what not, what we need to do to find the missing cases and giving attention to Read More
Sacema will expand its team in 2018. We are looking for mid-career researchers with doctoral degrees in a quantitative field and substantial experience in epidemiological modelling, study design, and data analysis. Areas of particular interest include TB, outbreak response, and emerging infections.
Sacema will organise a practical introduction course to Individual-based Modelling in Epidemiology in May 2018. Postgrad students, postdocs and health science professionals whose work potentially involves the design and/or use of individual-based models in epidemiology are invited to attend.
The biennial International AIDS Society (IAS) Conference on HIV Science was held in Paris, France in July 2017. This article presents some of the highlights of the conference, including the roll of PrEP and the promise of long-acting injectable ARVs, as well as contributions of SACEMA staff in the areas of HIV and Hepatitis C, and HIV and cervical cancer. Basic, clinical, epidemiological and operational research on HIV and the HIV response must continue to be prioritised even while we strengthen our health systems and improve the implementation of existing interventions.
SACEMA’s 11th annual ‘Research Days’ meeting took place over four days 21 – 24 August 2017, in Stellenbosch. All SACEMA funded students and their supervisors were invited, together with some associates and collaborators. The meeting included training workshops, keynote talks, formal research presentations, student and supervisor forums, and a debate.
SACEMA researchers Alex Welte and Eduard Grebe have written a provocative general-audience reflection on the system of ‘peer review’ in academic publishing. They argue that pre-publication peer review is a not needed anymore and the focus should be on post-publication peer review.
: In the context of an implementation research project, aiming at better aligning targeted services with the general health services, we conducted cross-sectional surveys among a representative sample of female sex workers (FSWs) in four cities. We explored, through structured face-to-face interviews, where FSWs procure commodities and services for sexual and reproductive health. We compared service utilization across the four cities and assessed if it was significantly different.
Abstract: Twenty years ago, in 1997, I wrote the following piece reflecting on the Mothusimpilo project, an early attempt to understand and help to manage the epidemic of HIV in South Africa. I thought it might be interesting for you to look back on where we have come from.
