There is no doubt that 2020 will be a year to remember.  A pandemic, national lockdown, social isolation, health risks, economic and academic disruption, and uncertainty, loss of control, fear, and panic due to information flooding are all ingredients in the perfect storm of the unprecedented ‘new normal’.  Due to COVID-19, we have become sensitised to the need to protect mental health and well-being among all members of society – not least, our caregivers.  The plight of healthcare workers in the front lines has focused our attention on the threat of burnout (defined as emotional exhaustion, depersonalisation, and a sense of low personal accomplishment) as a result of increased stress, as well as the risk of depression and anxiety disorders. 
 
Focus on becoming more agile and adaptable

But do we need to stick to the prescribed script that dooms us to global resignation of merely trying to survive?  Is there an alternative response that uncovers unique strengths? Can we flip the narrative to resilience?  

In the destructive wake of this global crisis, we could instead focus on how we have become more agile and adaptable. We could notice the coping strategies of those who do not succumb to despair, victimhood, or expedience.  We could reimagine a world where the problems of the day do not define us; a world where we respond with intention, drawing on resilience forged in the fire of adversity, resolutely using our prior-established values to guide us.

Resilience helps us to not merely survive, but to recover, regroup, and reach new heights.   Diane Coutu described the characteristics of resilient people:  stoic acceptance of tough situations, creating meaning despite the current overwhelming circumstances, and an astonishing ability to improvise.  The notion was reinforced in a recent perspective published in the New England Journal of Medicine.  The authors eloquently pointed out that during the uncertainty of the COVID-19 pandemic, a sense of altruism and urgency seemed to catalyse restored autonomy, competency, and relatedness – three pillars considered supportive of intrinsic motivation and psychological well-being.  

Adaptive coping strategies

Research among students and staff in the UFS Faculty of Health Sciences has shown that higher resilience (and lower burnout) is associated with adaptive coping strategies.  Strength and growth through hardship were foundational to dealing with endemic stress and inevitable personal, academic, and financial challenges. 

So, what are some of the qualities, skills, or resources that help us bounce back and grow our resilience, resulting in the crisis of the day (aka COVID-19 and its nasty sequelae) causing a (temporary) bruise, rather than a (permanent) tattoo?
Have hope.  Far from blind, naïve optimism, it is instead a sober realism about reality, balanced by finding strength in the belief that in the end, you will overcome (the Stockdale Paradox). This ties closely with acceptance, allowing emotions a seat at the table of our lives but not giving in to their attempts at a hostile takeover.  It happens when we choose to respond, rather than react, leaving space to be flexible enough to adjust our expectations from immediate gratification to the perseverance to sit out the discomfort.  

Stay kind.  In the face of extreme hardship, humans reveal the truth about themselves.  Treating others with compassion, patience, and respect may not make the crisis disappear – but when we look back, are we not most inspired by those who have created meaning through extraordinary humility and sacrifice?  When all is said and done, what story would you like to tell about the kind of person you were during the pandemic? 

Be brave

Be brave anyway.  Approaching the sixth month of the pandemic means that most of us are tired.  Despite trying to be safe, innovative, and wise, there are no apparent solutions or a clear end in sight.  This is the time to be insanely courageous, to step into the arena to find answers and offer alternatives, despite naysayers (often anonymous) criticising your best efforts. This is the moment in history when we need to overcome our fear with the kind of courage that shows up even when legs shake, the voice trembles, and the heart palpitates.

When we look back on 2020, may we do so knowing that we continued hoping (even while accepting the tragic reality), that we stayed kind (creating meaning in the midst of turmoil), and that we were brave (overcoming seemingly insurmountable difficulty with exceptional creativity).  We have much to offer if we allow our resilience to stand this test of time. May COVID-19 change us for the better.

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.
