As we as a South African nation prepare to celebrate Heritage Day on 24 September, and as we reflect on our heritage during Heritage Month, what stands out clearly is that this year’s heritage celebrations will be somewhat … different. It will not be like previous celebrations because as a country, we – along with our fellow continental and global citizens – have experienced what can be described as one of the greatest health, social, and economic challenges that we as a species have ever faced. The repercussions and impact of the COVID-19 pandemic will be felt for some time to come. And it is this realisation that may cast a little damper on our celebrations during this #Heritage Month.

But what can our shared heritage as South Africans teach us about who we are as a people, and how can this knowledge help us to adapt to and overcome the long-term challenges wrought not only by the pandemic, but also by the many other challenges facing us? 

Heritage Day is a celebration of our cultural heritage and diversity as a nation. It presents us with an opportunity to reflect on our individual and collective heritage. It is also an opportunity for us to take stock of the cultural and other resources that enable and empower us to take ownership of what we want to be as a nation, as a country, as a people. 
So, in view of the questions raised earlier, here are some ideas on what I think our shared heritage can teach us:

1. The heritage of where we come from

Inasmuch as our past is a painful one – a past that still has lingering effects decades after the transition to a democratic dispensation – it still plays a fundamental role in shaping who we are now, and who we want to become.
Colonialism and apartheid sought to suppress our indigenous cultures and traditions, and had a negative impact on our psyche, self-confidence, and dignity as indigenous and African people. But one positive that came from this, is that if it was not for our shared heritage of colonialism and apartheid, we probably would not have become the nation we needed to become to bring it to an end.  

Instead of destroying symbols of that painful past, we need to shift our perspective to re-interpret those symbols in a new way. The power of cultural symbols lies in their meanings. Symbolic anthropologist Victor Turner spoke about the ‘multivocality of symbols’, meaning that we can ascribe whatever meanings to our cultural symbols we choose. Let us reflect on how we can change the current meanings we ascribe to our cultural symbols that reflect an awareness of how the heritage of where we come from does not keep us trapped in negative and painful meanings of these symbols, but instead inspire us to create new positive meanings.

2. The heritage of where we are now

After 1994, we began the process of creating a new contemporary heritage as a nation struggling to free itself of the burden of a painful past. And while it was difficult, we have made significant strides. Yes, we do still face challenges rooted in the past: institutional and structural violence; race and diversity-related issues; intercultural and intergroup conflicts; crime and violence against men, women, and children; corruption at various levels of governance; and others. We are also faced with ‘newer’ challenges as a country that is part of the globalised world. Poverty, inequality, unemployment, slow economic growth, and ailing infrastructure are all contemporary problems, some of them rooted in the past, others the product of the contemporary context. 

What can we learn from our shared heritage of where we are now that can help us to overcome these contemporary challenges? We need to remind ourselves of what we are capable of as a nation. We have ended an oppressive regime, not once but twice. And, with all of the challenges, problems, and obstacles, we are still here.

3. The heritage of where we are going

This might sound strange, because heritage usually refers to the past and present. Rarely do we speak of heritage in a future-oriented context. However, as a nation, given our past and given our present, where we come from and where we are now determines where we are going. 

As South Africans, we need to ask the question: where do we want to go? Are we heading in that direction? If not, how do we change course so that we do go in the right direction? I have no simple answer. But what I can suggest is that it should start with critical self-reflection, both individually and collectively. We also need to ask ourselves what legacy we want to leave for future generations. Do we want them to still be struggling with the same problems and challenges that we are dealing with right now? Or do we want to leave them a legacy of a nation that stood up to its challenges, took ownership of them, and found a way to overcome them?

A globally devastating pandemic. A painful past. A present wrought with seemingly insurmountable obstacles. As a South African, as a child of the soil, I know that as a nation we can overcome, and we can emerge better and stronger. That is our heritage. The heritage of hope.

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.
