A data scientist and research coordinator at the University of the Free State (UFS), in collaboration with his supervisor at the University of Pretoria (UP), is at the forefront of the fight against the Covid-19 virus with accurate data and analysis.
Herkulaas Combrink of the Centre for Teaching and Learning at the UFS and PhD candidate in Computer Science at the UP, said accurate data is important to prevent widespread panic and sensationalism during a global disaster such as the current pandemic. This information helps people to make informed decisions and to reduce their exposure to the threat of the virus.

Assisting decision-makers

“I, along with colleagues from the World Health Organization, the Centers for Disease Control and Prevention in the USA, the provincial office of the Centers for Disease Control and Prevention, provincial clinicians, and the Free State Department of Health led by Dr David Motau, have been able to progress significantly in terms of evidence-based tools to assist provincial and national decision-makers during these turbulent times.”
“It does come at a cost, though, in that we have worked continuously since the lockdown, dedicating all our time and efforts to the department from all over to ensure that we are not part of some of the global statistics we have seen,” said Combrink. 

A paper written together with his supervisor, Dr Vukosi Marivate, has also been accepted by the Department of Higher Education and Training (DHET)-accredited Data Science Journal.  This paper is related to a framework for sharing public data to the public in a way that is useful, usable, and understandable. 

Ongoing projects

Combrink said it is hard to name all those who are/were involved in the great work done by the Free State Department of Health, but some of them include Dr Elizabeth Reji (Head of Department, Family Medicine), Dr Collin Noel (surgeon, senior lecturer at the UFS), Dr Sammy Mokoena (community health registrar, UFS), Dr Ming-Han Motloung (public health medicine specialist, senior lecturer, UFS), Dr Perpetual Chikobvu (Director: Information Management at the Department of Health, affiliated lecturer at the UFS), as well as Alfred Deacon (lecturer at the UFS), who have worked at some point during this short space of time on one of the many projects. 

Some of the projects include the following:

• A provincial database for screening and monitoring.
• A data pipeline and assembly of hospital information flow, liaised with the NICD, Vodacom, and the different district managers to ensure that the pipeline occurs in a timely manner.
• Digitised paper-based capturing tools for rapid data capturing and processing.
• Incorporated state-of-the-art visualisation tools to action data into useful information for decision-makers in certain areas.
• Provided both provincial and national projections, stress testing different scenarios using a variety of statistical, computational, and/or machine-learning approaches to add to the already existing projections of the Council for Scientific and Industrial Research (CSIR).
• Training healthcare professionals in the field to apply these tools within their own districts.
No easy task

“These aforementioned feats were by no means easy and are not completed yet, but we are getting there. In the foreseeable future, I will be working closely with national and international researchers to deploy a tool for hospital managers in the Free State that will assist them when we move from level 5 to any level below.”

“In addition to this, I am constantly providing support to the Free State Department of Health regarding any analysis required for decision-making purposes. The teams we work in comprise highly competent individuals with a passion for solving problems from multidisciplinary perspectives,” according to Combrink.

Mafuma aims at elusive tournament victory with Junior Springboks

He has never won a rugby tournament, so Mosolwa Mafuma has only one goal: to win the Junior World Cup as Junior Springbok in England.

Even though the 20-year-old Shimlas wing has achieved success, and it is pleasing to excel individually, he believes it is more satisfying when his team triumphs. According to Mafuma, who could just as well be an athletics star, he wants to help the South African U20 team take a different approach.

He and the prop Kwenzo Blose are players from the University of the Free State who will represent the Junior Springboks from 7 to 25 June 2016 in Manchester. The team will play the first of three group matches on 7 June 2016 against Japan in the Academy Stadium.

New approach for SA U20 team
Mafuma, who was Player of the Tournament in his first Varsity Cup in 2016, says the Junior Springboks are well prepared. “We have the skills, and the structures at the Junior Springboks are different than before. There is not just one game plan like playing with big guys. We want to try new things and have a different approach.”

It is with this team that he wishes to achieve something. “It is one thing to be able to say that you are the Player of a Tournament, but your team did not win. I have not won something at school (with St. Benedict’s Boys College in Johannesburg) or this year with the Shimlas.”

Speedster on athletics track
The speedster is one of only a few rugby players who also have a profile on the IAAF website. His fastest time in the 100 m is 10.37 seconds (a national U17 record) and 20.37 s in the 200 m.

In high school, this first-year Psychology student played rugby during winter and took part in athletics during summer. Only at the end of Grade 11 did he started focusing on rugby. “I was more of an athlete than a rugby player,” he says.

It is no coincidence that the nickname he acquired due to his speed, is Dash. His other nickname, Senkie (derived from the Afrikaans word ‘seuntjie’) he received as a child from his parents because he was such a small child.
