Social media discussions have provided a lens on how people are dealing with and talking about COVID-19. This has given risk communication new insights into online audiences.

The lingering effects of the COVID-19 pandemic on society presented the experts at the University of the Free State (UFS) with an opportunity – to conduct a scientific study by analysing our social media data in order to assist government health communicators to reflect on their communication strategies and, in turn, gain new perspectives from the general social media user (public). 

The study – led by Herkulaas Combrink, a data and medical scientist in the UFS initiative for Digital Futures, and Prof. Katinka de Wet, medical sociologist in both the UFS initiative for Digital Futures and the Department of Sociology at the UFS – uses “real-time snapshots of online interactions as a means to augment more traditional methods of conducting research on a given topic; in this case, responses to COVID-19”, said Combrink. 

The findings and ongoing work of the research project were presented to the Parliamentary Portfolio Committee on Communications. “During this meeting, critical engagement took place around risk communication and areas where we can strengthen this research,” said Combrink. Several international influential risk communicators on the African continent were present. 

Digital science at the forefront 

The opportunity to pursue this study was the result of Herkulaas Combrink’s secondment to the Free State Department of Health (FSDOH), where he identified the need to develop additional analytics for the already existing processes in risk communication in order to assist various communication strategies linked to developments regarding COVID-19 infections.  

Combrink also said “because the analysis of social media data does not normally form part of the traditional toolbox of investigation for this type of work, this novel application serves as an addition to the already existing communication analytics”. This research project will strengthen the level of cooperation between the UFS, other institutions, and the FSDOH to “synergistically strengthen communication strategies in relation to COVID-19”. 

By looking at how new knowledge around COVID-19 is developing the method (of analysing social media data), is to stay abreast of trending and burning issues on open-source social media platforms. “It is important to conduct this work using well-defined scientific methodology to extract, explore, analyse, and report on the data,” Combrink says. 

Given the rapidity with which new knowledge around COVID-19 is developing all over the globe, this method lends itself to staying abreast of emergent and burning issues that are trending on open-source social media sites. 

Variety of stakeholders needed

The magnitude of the research study required the involvement of stakeholders from different institutions. “A variety of stakeholders from different institutions are needed not only to contextualise the data, but also to provide social and technical input to solve the problem,” Combrink said.  

Experts included in the project are Dr Vukosi Marivate from the Department of Computer Science at the University of Pretoria, Dr Ming-Han Mothloung from the Department of Community Health at the UFS and the FSDOH, and Dr Samuel Mokoena, Priscilla Monyobo, Mondli Mvambi, and Elke de Witt from the FSDOH. “Without this core team, the work would not have been contextually relevant,” Combrink said.

Many people are interested to know more about their history and origins, and with the help of genetics, it is possible to provide more information about one’s roots.

During a lecture at the Department of Genetics at the University of the Free State (UFS), Dr Cristian Capelli, Associate Professor of Human Evolution at Oxford University in the UK, addressed staff members and students on the history of our species.

Reconstructing the history of human population
With his research, titled: People on the move: population structure and gene-flow in Southern Africa, Dr Capelli looks at reconstructing the history of human populations, focusing mainly on how the different human populations are related, as well as how they exchange genes.

He said this research could be of great significance to the medical field too. “Knowing what the genetic make-up of individuals is, can give us some information about their susceptibility to diseases, or how they would react to a given medicine. Therefore, this knowledge can be used to inform health-related policies.”

Combining individual histories of multiple people
To understand this research more clearly, Dr Capelli explained it in terms of DNA and how every individual receives half of their DNA from their mother and half from their father just as their parents had received theirs from their parents. And so it goes from generation after generation. Each individual stores a part of their ancestors’ DNA which makes up the individual genetic history of each person.

“If we combine these individual histories by looking at the DNA of multiple people, we can identify the occurrences that are shared across individuals and therefore reconstruct the history of a population, and in the same way on a larger scale, the history of our own species, homo sapiens.
