Voices from the Free State: Episode ten – featuring Louzanne Coetzee

15 November 2021 | Story Dr Nitha Ramnath | Photo Supplied

“Running provides me with a platform to reach others, to bring hope, to make people realise that anything is possible if you are prepared to work hard for it,” says Louzanne Coetzee, our very own home-grown all-round achiever, who is fun-loving, relatable, and inspiring. A South African para-athlete, Coetzee was born blind as a result of a hereditary condition called Leber congenital amaurosis, and competes in the T11 disability class for athletes with the highest level of visual impairment. Coetzee enjoys an integrated life, with an interest in baking, watching movies, walking and hiking, cycling, being part of a church band, public speaking, coupled with some artistic hobbies.

Our podcast guest

Coetzee competed at the 2020 Tokyo Paralympic Games this year, where she won a silver medal in the 1 500 m final alongside her guide Erasmus Badenshorst, setting a new African record of 4:40.96. She also competed in the women’s mixed class marathon (T11 and T12 for the visually impaired) with her guide Claus Kempen, improving the world record by 1 min 42 sec and her personal best from 3:13:41 to 3:11:13.

In 2018, Coetzee competed in three events at the Para Athletics event in Berlin, Germany – the 800 m, 1 500 m, and 5 000 m. She set a new African record in the T11 800 m race, taking the silver medal, as well as a bronze for the 1 500 m race. In 2018, Coetzee also broke the 5 000 m (women) world record in her disability class, while in the same year she became the first visually impaired athlete to compete at the World University Cross Country Championships in Switzerland.

Coetzee set a new world record in the 5 000 m T11 category for the first time at the Nedbank National Championships for the Physically Disabled in March 2016. Moreover, with her performance of 19:17.06, Coetzee shattered the Lithuanian athlete Sigita Markeviciene’s 16-year record of 20:05.81, set at the 2000 Paralympics in Sydney. Coetzee became the first totally blind female to clock sub-20 minutes in the 5 000 m.

Her involvement in her society stretches beyond sports, and as a student, she formed part of the University of the Free State Student Representative Council. She was also an athlete representative on the Free State Academy of Sport’s executive committee.

In 2014, she became the first visually impaired student to be elected to the UFS Student Representative Council (SRC), with the portfolio Student Accessibility. From 2015 to 2017, she was a research assistant in the Institute for Reconciliation and Social Justice at the UFS, and in 2016 she also acted as junior lecturer in a computer module for students with visual impairments. From 2017 to 2018, she was Residence Head of Arista Ladies City Residence, and she is currently the Residence Head of Akasia Residence at the UFS.

Coetzee boasts several accolades from the UFS. She was named the 2014 Senior Sportswoman of the Year by the Free State Sport Association for the Physically Disabled (FSSAPD). In 2017, she and her guide Khothatso Mokone received a Special Award for Disabled Sport at the KovsieSport Awards. In 2018, she won the Free State Sports Star Award, and was named Sports Star of the Year (period June 2018 to April 2019) by the Free State Sport Association for the Physically Disabled.

Coetzee’s academic qualifications include a BA and BAHons in Integrated and Corporative Marketing Communication, and an MA in Social Cohesion and Reconciliation – all from the University of the Free State.

Listen to the podcast below

François van Schalkwyk and Keenan Carelse, UFS alumni leading the university’s United Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series. Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month, ending in November 2021. Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

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.
