In IsiZulu, there is a saying that goes, ‘indlela inbuzwa kwa ba phambili’, which can be loosely translated into, ‘direction is asked for, from those who’ve walked the path’. According to the illustrious Credo Mutwa, in his seminal masterpiece, Indaba my Children, 

“these are the stories that old men and old women tell to boys and girls seated with open mouths around the spark-wreathed fires in the centres of the villages in the dark forests and on the aloe-scented plains of Africa. Under the gaze of the laughing stars the Old One sits, his kaross wrapped around his age-blasted shoulders, staring with rheumy eyes at the semi-circle of eager expectant faces before him – faces of those who have taken but a few steps along the dark and uncertain footpath called Life – faces of the ones yet oblivious to the pain of life’s bitter scourges – faces yet unmarked by furrows of bitterness, ill-health and anger – the fresh, pure, open faces of…children. The fire dances in the middle of the round clay fireplace like a virgin revelling in the simple joy of being alive. It devours the dry twigs and logs that a little girl is constantly feeding it, leaving nothing but glowing ashes. It mocks the silent sky with a redly luminous column of smoke against its starry face and by sending up short-lived stars of its own”|

As the birthplace of humankind, the motherland, homeland, and ancestral origin of everyone on the planet, Africa is a blessed, special, and beautiful continent. It is an expansive abode of rich diversity, striking complexities and ornate nuances and peculiarities, both in its people and in its biomes.

With approximately 2 100 languages spoken by more than 3 000 ethnic groups in our population of just over 1,3 billion individuals spread across 55 countries, Africa is culturally, philosophically, and linguistically a very wealthy land.
Our shared, priceless heritage is littered with shining examples of the excellence, resilience, ingenuity, fortitude of character, strength, spirit, and love of our people. We have adapted to desertification, unshackled ourselves from slavery, replenished ourselves from years of famine, battled deadly viral diseases, nursed ourselves out of internecine conflicts, liberated ourselves from colonial oppression, and together, through it all, held fast the inherited role we collectively hold as custodians of humanity.

As Enock Maregesi spiritedly states:
“We are the children of Nelson Mandela; we are the children of Kwame Nkrumah; we are the children of Haile Selassie; we are the children of Samora Machel; we are the children of Robert Mugabe; we are the children of Patrice Lumumba; we are the children of Julius Kambarage Nyerere. We know who we are!”

And in this reverent knowledge of who we are, where we come from and what we have experienced to bring us to this present day where we celebrate our languages, our customs, our traditions, our ethnicities, our similarities and differences, our uniqueness, our Africa, and by virtue of that, our Africanness, we not only remember, but resonate with the heart-stirring words of Dr Kwame Nkrumah, “I am not African because I was born in Africa, but because Africa was born in me!”

We are grateful for the providence with which our continent has been virtuously spared from the unprecedented eventualities that have become synonymous with the leap year of 2020. The onset of the global lockdowns following the declaration of COVID-19 as a pandemic, averted a situation that could have escalated into a third world war; decreased the worldwide carbon emissions and pollution drastically; and served as a clarion call to unite humanity in the common goal of the preservation of human life. In spite of the hardships that came with re-adjusting our focus back to self-sufficiency, self-preservation through social distancing, and redefining what we term as essential, all of humankind has joined in remembering. Remembering how to do for self, remembering to care for those in need, remembering to cherish and respect the planet, and most importantly, remembering their African ancestry.

As we dutifully charter forth through the eternal passage of time, continuously evolving in conscious intelligence, consistently preserving human existence and steadily riding the throes of modernisation by globalisation, we invite all of humankind to take heed of our guidance, and ask for direction from those who have walked the path before. Let us illuminate the way forward for our planet by using the knowledge and ways that have been laboriously and painstakingly preserved for us by our forebearers though centuries of oppression, apartheid, discrimination, and derogation. 

We overcome. We inspire. We rise. We adapt. We thrive. It is our legacy to steer humankind back home, back to basics, back to mother earth. The historic events that have marked the first half of 2020 have highlighted to the world the inescapable importance of the cardinal African values of Ubuntu and a sustainable co-existence with nature. 

No, we are not African because we are born in Africa, we are Africans because Africa is born within us. Let us construct for the world a new model of being, a model of old, a model of nature, a model of our African nature.

On this Africa Day, go forth African child, and remember your sacred duty. Live your glorious destiny. Show the way for the rest of humanity. Mayibue!!!

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.
