The Hollywood movie, Contagion, acutely reminded me of the impact of COVID-19 on our education our education system. The many parallels between this movie and what is unfolding worldwide today in unbelievable. Nine years ago, who would have predicted that the world would find itself right in the middle of the plot and enacting the scenes in Contagion?

There is growing concern about our education system with many asking whether the school year is ruined.

For some it may be ruined and for others less so. Parents for disadvantaged communities do not have the means, knowledge and resources to support their children’s learning during the lockdown whereas those from more advantaged communities may access information on Department of Basic Education (DBE) and other websites to support home schooling during these times. For those who did not have these opportunities the loss of school time may thus have a much greater impact.

Embracing homeschooling
However, the school calendar year may equally be extended to early next year. In any event, we already have a system that allows for aggrotats, supplementary exams that runs into the new year, each year. The academic year can be aligned to close accommodate the lost time.

This is the right time for parents to embrace homeschooling of their children. UNESCO’s “COVID-19 Education response” provides a list of educational applications, platforms and resources aims to help parents, teachers, schools and school administrators facilitate student learning and provide psychosocial support during periods of school closure. Most of the solutions are free and many cater to multiple languages. The lists are categorised based on distance learning needs and most of them offer functionalities across multiple categories (https://en.unesco.org/covid19/educationresponse/solutions).

On the one hand, for the majority of learners and students in South Africa, especially from impoverished communities, distance learning will pose a great challenge. Majority of these communities have less access to digital devices and online solutions. The DBE should work with the SABC and consider opening a free 24 hours learning channel, as a platform to provide further support to distance learning and teaching. Radio remains the cheapest and most effective means for this

On the other hand, the situation is different with some private or IEB schools. Most learners from these schools are already trained to use distance learning platforms.  For example, during this lockdown, my 13year old niece starts her school day at 07:30 every day without fail. The school uses several strategies including the Microsoft Teams to support teaching and learning. Each learner has a laptop, completes home-work, assignments and write open book tests. In this scenario, at least 80% of efficient learning and teaching occurs. The difference between the two scenarios is a matter of inequalities, equity and poverty which still prevalent in South Africa.

An unequal school system
For many years the slogan was: “Liberation first then education” maybe it is time for “life and health first”. Even in the most difficult times people have found a way to learn – think of those on Robin Island in the apartheid years. We should imitate their example and not wait for the government to provide. Maybe libraries are an essential function that should remain open in these times.

Protracted student protests in South Africa over the past few years gave universities an opportunity to explore online education as an alternative to contact teaching and learning, and have put them in a better position to deal with current shutdowns necessitated by the need to contain COVID-19.

The pandemic exposed the glaring inequalities, equity and poverty that continues to exist, in particular, in education systems and country in general. Those who have the latitude to remain indoors and maintain the social distancing are the middle and upper classes of our society. These groups have access to data to support online educational programs, while the poor barely survive to put food on their tables.

For many years the world was expecting a virus that could spread globally (e.g. the swine flu) but nothing was done. With the myriad of challenges facing, including downgrading to a junk state, funds depleted through corruption at various levels, our country could not be at a worse position than now.

Lessons from the lockdown
One lessons from the lockdown has exposed the failures and shortcomings of not only our education system, but also the entire ecosystem. Huge inequalities still exist in education systems across the globe. Universities are grappling with a myriad of problems including teaching online.  The COVID-19 pandemic forced campuses to shut down and move many functions like graduation, examinations, conferences and other collaborations to the back. Another positive outcome of the pandemic is the sense of unity it created among political, cultural, religious and social organisations in South Africa and across the globe. Consequently, the most important lesson is that lives matter more than education.

As our president, Cyril Ramaphosa said, “We are currently in unchartered territory, which we have never had to navigate before”. It is therefore, very difficult to forecast the full degree of the short-, medium- or long-term impacts of the COVID-19 pandemic on the education system. The longer the virus remains, the greater and more permanent changes may be. Certain things will probably change forever. Not only will our conception of going to office to work alter, but also our whole conceptualization of what a university is will change. We will probably see universities becoming more and virtual and operated from a highly decentralized basis.

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
