South Africa has established itself as a regional higher education hub, which has until the recent COVID-19 pandemic been hosting increasing numbers of international students. The vast majority hails from the neighbouring countries in the Southern African Development Community and includes increasing numbers of postgraduate students, specifically doctoral students. The country has become one of the global epicentres of the pandemic. We argue that while the country is grappling with combating the virus, its higher education system and stakeholders must keep focusing on the post-COVID-19 future. The way the country and its higher-education system treat international students in the present crisis may determine whether it will be able to retain its position as a regional higher education hub, and whether it will be able to be a driver for PhD capacity development in the SADC region and Africa following the pandemic.

South African higher education has promoted ethical practices that govern their engagements with international students. The Code of Ethical Practice – accepted by all South African universities, guide the university’s actions for all phases of study, including the phase where students would be required to go home and return for studies. The common obstacles influencing international student mobility to and from the country caused by the lack of cooperation by government departments, should not have been a problem in this case, as all activities are coordinated by the South African National Coronavirus Command Council (NCCC). According to South Africa’s President, Cyril Ramaphosa, “the NCCC coordinates government’s response to the coronavirus pandemic. The NCCC makes recommendations to Cabinet on measures required in terms of the national state of disaster. Cabinet makes the final decisions”. (Written response by the President to written question NW 725 by Adv. G Breytenbach dated 5 June 2020.)  

International Students in the Initial Phase of the COVID-19 Crisis
The lockdown that the country imposed in March 2020 to combat the pandemic, resulted in a large part of its international student population returning home, particularly those hailing from neighbouring countries for whom travel was easy to organise. At the time, it was anticipated that students would be able to return after a three-week lockdown of the country. Most universities expected that their international students would come back to campuses after an extended recess in April 2020. At many universities, international offices assisted international students with travel arrangements and organised for those unable to travel, mostly students from other regions of the world, to remain in university residences until campuses would reopen. International students expected to be able to return to their universities soon, resulting in many travelling light and leaving essential learning, research, and personal items behind in residences.

However, controlling the COVID-19 pandemic proved far more complicated than anticipated, and the lockdown was replaced by a risk-adjusted strategy that provides for five alert levels, of which level five has the most severe restrictions on public life. As the country progressed to level four on 1 May 2020, South African universities were permitted to resume face-to-face classes for final-year medical students. On Wednesday (13/5), directions were gazetted that “allow for the once-off travel of final-year medical students studying at a public higher education institution to travel from their homes to the university campus where they are registered for study during the period 8-31 May 2020” (GG No. 43319 of 13 May 2020). No clarity was provided on whether this would include international students; the wording was at least wide enough to allow for this. Stakeholders interpreted the regulations in different ways, but at least a limited number of international final-year medical students returned from Lesotho. 

Preparation for the Resumption of Select Face-to-Face Classes 
When the South African Minister of Higher Education and Training, Dr Blade Nzimande, charted the way forward for South African higher education during the COVID-19 pandemic, he enunciated the principle that “all students should be given a fair opportunity to complete the academic year 2020” (speech on 23 May 2020). In this political announcement, he stated that final-year students in programmes requiring clinical training (e.g. nursing, and dental sciences) would begin from 1 June 2020. He postulated that other critical groups of students, including final-year and postgraduate students who require access to laboratory equipment, should be allowed to return to the country’s campuses. He did not refer in any way to a planned exclusion of international students, and at least some universities included international students in their planning for the resumption of select face-to-face classes in June 2020. 

International Students in Basic Education
When the teaching of select grades in basic education resumed in South Africa in June 2020, students from neighbouring countries were allowed to resume their daily commutes across the South African border according to regulations gazetted on 28 May 2020 (GG No. 43364 of 28 May 2020). It appears from individual reports received from border posts that boarding school students are returning from Lesotho and Botswana.

International Students in Higher Education   
As the country moved to alert level three on 1 June 2020, some stakeholders in South Africa’s higher education system anticipated that at least international students from neighbouring low-risk countries such as Lesotho or Botswana would be allowed to return when their face-to-face classes would resume. Directions issued by the South African Department of Higher Education and Training on 8 June 2020, however, unequivocally stated that ‘international students who returned to their home countries during the lockdown will only be permitted to return to campuses when Level 1 of the strategy is announced’ and explained, without elaborating on detail, that ‘these international students will be supported through remote learning until they return. Tailored catch-up plans will be implemented when they return.’ Consequently, many international students are likely to return after face-to-face classes in their modules have recommenced, and it is left to individual higher-education institutions to ensure that they are not ‘left behind’. Core challenges to ensure this include the cost of data in the main source countries of international students, as well as limited internet speed. Some universities are trying to alleviate this by providing data allowances for international students; however, this is not yet practised uniformly throughout the sector. 

Core Challenges 
To avoid harm to South Africa’s reputation as a preferred destination for international students, the country and its higher-education system will have to find satisfactory answers to critical questions:

• How can the South African higher-education system ensure that no international student is left behind in modules for which face-to-face classes resume, especially considering those who require clinical/laboratory training? A recent webinar between Vice-Chancellors from six SADC countries highlighted the fact that connectivity and data availability throughout Southern Africa is still one of the biggest challenges facing all higher-education systems. Not only the South African system, but all other SADC universities will have to be innovative to resolve this problem, especially where all have committed themselves to not leave any students behind.

• Who will bear the considerable cost for necessary interventions, such as the provision of data to international students abroad?

• How can the training of critical professions for combating COVID-19 in Southern Africa be sustained at South African higher-education institutions when degrees such as medicine (MB ChB degree) require clinical training and examinations through a practical component?

• How can reputational damage to South Africa as a destination for international students be avoided when, apparently, high school students from (at least) Lesotho are allowed to enter the country and return to boarding schools, but students in critical health science degrees are not allowed to return to classes?

Way forward
We posit that careful balancing of the often conflicting priorities of combating COVID-19, ensuring that no international students are left behind, and sustaining the training of professionals who are critical in the fight against COVID-19 in Southern Africa, is necessary to ensure that South Africa contributes optimally to the fight against the pandemic in Southern Africa and sustains its position as a preferred destination for international students post-COVID-19. It will be important to demonstrate to the world that the country is living up to its world-renowned Constitution, which entrenches equality as a fundamental right. Any differentiation between international and local students, as well as between secondary and tertiary education students, which does not have a rational connection to a legitimate government purpose such as protecting public health, may infringe the country’s internationally celebrated Constitution, taint South Africa’s standing as a higher education hub, and jeopardise its existing reputation as a preferred destination for international students. Moving forward, thoughtful action is required to ensure that future generations of international students choose to study in South Africa following the pandemic, and to encourage those who left in haste when the COVID-19 crisis intensified, to return to complete their studies.

Fight against Ebola virus requires more research
2014-10-22

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.
