SACEMA Newsletter: December 2020

We wish all our friends, colleagues, students and collaborators a safe and peaceful Holiday Season!


Congratulations to our newest NRF-rated researcher


SACEMA researcher, Dr Olatunji Adetokunboh recently received a C-rating from the National Research Foundation (NRF). NRF defines C-rated researchers as established researchers with sustained recent records of productivity in the field and are recognised by their peers as having produced bodies of quality work, the core of which has coherence and attests to ongoing engagement with the field. Olatunji joined SACEMA in September 2019 as a National Public Health Liaison/Researcher. We are extremely proud of Olatunji and celebrate this achievement with him!



SACEMA talks Science

As scientists, we are accustomed to communicating our research to other scientists. However, there is often a disconnect when we have to communicate our science to the general public. Despite the challenge, science communication is an essential aspect of doing science; afterall, research aims to inform both policy makers and those who will benefit from our research outcomes. To this end, Jive Media Africa presented a two-day virtual science communication workshop to all SACEMA staff and students between 21 and 35 years of age. Click here to read more.

Implications of COVID-19 in high burden countries for HIV/TB

The triple burden of coronavirus disease 2019 (COVID-19), tuberculosis (TB) and human immunodeficiency virus (HIV) is one of the major global health challenges of the twenty-first century. A thorough understanding of HIV/TB and COVID-19 pandemics is important as the three diseases interact. A systematic review was conducted to evaluate different studies on SARS-CoV, MERS-CoV or COVID-19 associated with HIV/TB co-infection or only TB, to understand the interactions between HIV, TB and COVID-19 and its implications on the burden of the COVID-19 among HIV/TB co-infected or TB patients, screening algorithm and clinical management. Fourteen studies were included for descriptive analysis and seven studies were included in the meta-analysis. Click here to read more.

Key questions for modelling COVID-19 exit strategies

SACEMA’s Director Prof Juliet Pulliam and Research Fellow Dr Carl Pearson recently co-authored a paper entitled “Key questions for modelling COVID-19 exit strategies”, published in the Proceedings of the Royal Society of London — Series B in August.This paper was a large collaboration, resulting from a workshop on “Models for an exit strategy” as part of the Isaac Newton Institute’s Infection Dynamics of Pandemics programme. The paper explores how models can contribute to decision-making related to loosening of restrictions put in place to curb the spread of the COVID-19 pandemic. It emphasizes the need for better parameterization of epidemiological models, the importance of capturing heterogeneity, and requirements for data collection. Click here to read more.

The scale and dynamics of COVID-19 epidemics across Europe

SACEMA research fellow, Brian Williams recently co-authored a paper entitled “The scale and dynamics of COVID-19 epidemics across Europe”, published in the Royal Society Open Science. In this paper the researchers found that countries in Europe with fewer deaths locked down earlier, had shorter epidemics that peaked sooner and smaller populations. As lockdowns were eased, they expected, and duly observed, a resurgence of COVID-19 across Europe. Click here to read more.

Giving birth to a teenage-sized baby! Isn’t that impossible!

Professors John Hargrove and Glyn Vale, together with colleagues at the Liverpool School of Tropical Medicine and the Universities of Bristol, Greenwich, and California Riverside, recently published an essay that explores the extreme reproductive strategy of tsetse and how the control of this disease vector is influenced by an enormous nutritional investment in its young.

Arrivals and departures


Lactatia Motsuku joined SACEMA in the second semester of 2020 as a PhD candidate in Epidemiology at the Department of Global Health. Her research supervised by Dr Mazvita Muchengeti, Ms Cari van Schalkwyk and Prof Juliet Pulliam, focuses on liver cancer and Hepatitis B virus in South Africa. Lactatia will be focusing part-time on her PhD while being employed as an Epidemiologist at the National Cancer Registry Department of the National Institute for Communicable Diseases (NICD).





At the end of August we said goodbye to Dr Joseph Sempa, who took up a position as a Senior Lecturer at the University of the Free State in Bloemfontein. Joseph has been part of the SACEMA family since 2014 when he enrolled as a PhD student. After completing his PhD in 2017, he joined the Measuring Infection team as a postdoctoral research fellow, working with Prof Alex Welte on antiretroviral treatment monitoring. Joseph will continue to collaborate with SACEMA as a Research Associate. We wish him all the best with his career and look forward to continuing our collaboration with him.




We also bid farewell to Emanuel Dominic who took up a position as a Data Science Consultant at Wimmy. Emanuel joined SACEMA in 2017 as an MSc student, and after graduating with an MSc in Statistics, he was appointed as a Junior Researcher in 2019, where he worked closely with Prof Juliet Pulliam on various projects. Emanuel will also continue to collaborate with SACEMA as a Research Associate. We wish him all the best with his career and look forward to continuing our collaboration with him.

TCA Writing Course

The Conversation Africa (TCA) developed a self-paced/self-study online science communication course. The 90-minute course is interactive, short and packed with empowering tools to help scientists unpack and communicate their research, insights and expertise with the general public i.e. beyond academia. The Conversation Africa offered the training to a number of SACEMA’s academics, staff, PhD students and postdoctoral fellows, and Research Associates. A total of 18 participants registered, completed the course and received certificates of completion. Participants reported that it is a great resource when writing for the media, and found many useful tips on how to transition from academic writing to writing for the media.
