Prof Gert van Zyl, Dean of the Faculty of Health Sciences, presented a copy of the book to Prof Francis Petersen, UFS Rector and Vice-Chancellor.

Looking at the history and highlights of the Faculty of Health Sciences at the University of the Free State (UFS) you will find a golden thread of innovation running throughout. The faculty has not been afraid of the unknown and its focus has always been on patients and quality academic education.

This is according to Prof Gert van Zyl, Dean of the faculty, who gave an overview at the virtual launch of the book: The History of the Faculty of Health Sciences: 2004 – 2020 on Tuesday (17 October 2020). Prof Johan Diedericks, Emeritus Professor in the Dean’s office, is the author of the book.

This book launch was part of the faculty’s 50-year anniversary celebrations.

A two-year journey

Prof Diedericks said the journey to materialising the book started two years ago when Prof Van Zyl “coaxed” him into compiling it. “At that stage I was writing the history of the Department of Anesthesiology and still had a 6/8 clinical appointment which meant I only had one day a week free to work on the book.

“But it was time well-spent. It started off with reading a lot of minutes and annual reports but at the same, time I requested and begged (but did not threaten) the departments for information. That was quite difficult. Several people assisted me in getting the information but the material came in slowly” said Prof Diedericks.

There was also cooperation from all the heads of schools who eventually made sure he got the information he needed. He wrote some of the sections himself and also edited and re-wrote parts of the information he received to ensure everything is the same format.

The book consists of eight chapters and five appendices with graphs and statistics. Chapter one is an overview of the changes since 2004 the present day and chapter two is about the office of the dean followed by the five schools in the faculty and all the departments within the schools.  The last chapter has information on other sections such as the Frik Scott Medical Library, National Health Laboratory Service, the SA Doping Control Laboratory (SADoCoL) and student organisations.

Faculty highlights

Prof Van Zyl said he was sure the experiences learnt from the past 50 years had prepared the faculty to survive 2020 – the year of COVID-19. In his overview, he spoke about the human contribution.

“The human contribution is the mortar between the bricks of this faculty, our staff and students not just today, but over 50 years. Looking at the history of the faculty and reflecting back, it was built by the collective and individual efforts of women and men in the faculty to ensure that each and every step is taken with integrity and quality to take us forward.”

He said he hopes this history will not only offer adequate information to appreciate the huge contribution that members of the Faculty of Health Sciences, the university community, and the entire Free State had made in health over the past 50 years.

Re-inventing yourself 

Prof Francis Petersen, UFS Rector and Vice-Chancellor, who received a copy of the book from Prof van Zyl, had a message to every one attending the virtual event: “If you don’t understand your history, where you come from, it is very difficult to know where you are going.

“In a learning environment such as the university, we always have to renew ourselves and you can renew yourself through what is happening in your current environment, through what happened in your history and also through what is happening in innovation going forward. I think that is the message captured in this book.

“There are various re-inventions that happened over this period and we should continue with that going forward as members of the faculty, as students, and as alumni of the faculty. The faculty can even go far beyond where it is at the moment. But we must remember we are standing on the shoulders of individuals who made major contributions, not only to the faculty, but to the province, to the country and internationally. We have a duty and responsibility to build on that and I know the faculty is doing that,” concluded Prof Petersen.

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
