RETURN OF STAFF AND STUDENTS TO ALL CAMPUSES AS FROM 1 JUNE 2020

Message by Prof Francis Petersen, Rector and Vice-Chancellor

Dear Colleagues,

I hope that you are well, healthy, and safe. Since my last message to you, President Cyril Ramaphosa has announced that our country will move to Level 3 of the national lockdown on 1 June 2020. Subsequently, Dr Blade Nzimande, Minister of Higher Education, Science and Innovation, announced specific measures for the post-school education sector in response to the COVID-19 epidemic under Level 3, in order to re-integrate staff and students on campus.  

Over the past few weeks, a tremendous amount of work has been done to ensure the continuation of the Academic Project, and to prepare our campuses for the return of staff and students, ensuring that it is aligned with national directives and protocols. This was no small task. In a crisis, we have to do more than expected, and we have to go beyond the call of duty. During the past two months, I have seen and experienced many instances where multi-functional teams effectively engaged to ensure the continuity of the Academic Project, and the ongoing functioning of the university’s operations. I am immensely proud of what has been achieved so far.

The impact of the COVID-19 pandemic has forced us to explore and implement many innovative ways to ensure sustainability and survival. The university management followed a risk-based approach in devising a plan to continue providing tuition and academic activities to students during this time, and to complete the 2020 academic year. Over and above this, we have ensured that our campuses are ready for the return of staff and students from 1 June 2020. In our planning, a phased-in approach is followed to limit the number of staff and students present at a single location at any given time. This is in line with the national directive that a maximum of 33% of the university’s staff and student population may be allowed on campus during Level 3 of the national lockdown.

The Special Executive Group (SEG), which I chair, and which was established at the beginning of March 2020, continues to meet weekly to discuss and decide on the university’s response to COVID-19 as this pandemic develops over time. Consisting of a number of task teams, the SEG is the decision-making entity that responds rapidly, and in a coordinated manner to combat the threats to business continuity. It also identifies opportunities where the intellectual knowledge base of the university could be utilised to impact society positively.

As from 1 June 2020, all staff members – except those categories of staff specifically mentioned in the re-integration plan – will continue working from home during Level 3, until such time as they are officially informed by their line managers to return to work. However, staff members may be expected to return to work during this period if the situation so requires. Staff members must therefore be available and contactable by their line managers at all times during normal UFS working hours.

Staff members returning to campus as from 1 June 2020 will include academic staff who support and lecture our returning students, as well as support staff in specifically identified business areas. I want to assure you that your safety, health, and well-being remain our first priority when you return to campus. Teams from University Estates and other business areas have worked tirelessly over the past weeks to prepare the campuses. This includes the disinfection and deep cleaning (where necessary) of open areas and the hygienic preparation of the campuses (e.g. hand sanitisers, hand-washing stations at, for instance, entrance gates and areas with high pedestrian traffic, Perspex screens installed in high-traffic reception areas where face-to-face engagement is needed, and social distancing markers in high-traffic buildings). Similarly, lecture halls are also being prepared to ensure social/physical distancing.  

Strict access protocols will be maintained at the campus entrances during Level 3 of the national lockdown. Only staff and students authorised to return to the campuses and issued with authorisation letters will be granted access to the campuses. The wearing of masks is compulsory when entering the campuses and proof of screening must be provided. An online screening questionnaire has been designed for this purpose. These measures will help ensure that it is safe for staff and students to return to our campuses. 

Residences on the three campuses are currently being prepared to receive students. This includes the installation of hand-sanitiser stations at the entrances of buildings and maintaining social/physical distancing in the general areas. Daily screening of students in residences will be compulsory.

I am attaching a document that explains the re-integration plan for Level 3 in detail, including the arrangements for the return of staff and students to our campuses: the categories of staff and students, entry to the campus, wearing of cloth masks, social distancing, environmental hygiene, protocol for on-campus meetings, vulnerable members of staff, staff with minor children, public transport, and the management of visitors during this period. The plan will be amended as and when needed. 

It is important that you maintain regular contact with your team and fellow colleagues. Most of our staff has been working from home for more than two months, and I know you might be missing the collegiality and campus environment. I want to encourage you to be patient, to look after your physical and mental health, and to make use of the resources available from the Department of Human Resources.

COVID-19 has provided us with opportunities to rethink the world of higher education afresh, and its impact has been transformative and forced us to think beyond the pandemic.

May you have a good and restful weekend – remember to #StayAtHome.

Regards,
Prof Francis Petersen
Rector and Vice-Chancellor

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
