The Easter weekend runs the risk of being a major catalyst for the third wave and people’s behaviour will be the primary driver of transmission for the third wave.

Similar trends as during the festive season of 2020 – when the behaviour of people was driving COVID-19 transmissions and played a role in the second wave – have emerged due to the Easter holidays, and may contribute to a third wave. 
“This means that we can already anticipate gatherings and a higher rate of travel during the next three weeks. As a result of this as well as non-adherence to the non-pharmaceutical interventions, we can anticipate this event to serve as a catalyst for transmission.” 

“If nothing is done to prevent this, it is anticipated that the Free State will see a steady increase and a potential third wave between 17 April and 26 June,” says Herkulaas Combrink, the interim Director of the UFS Initiatives for Digital Futures and PhD candidate in Computer Science at the University of Pretoria (UP).

The Easter weekend runs the risk of being a major catalyst for the third wave

According to him, the vulnerability and population density dynamics in each province, the behaviour of people, and the social norms between communities must be taken into consideration to contextualise the impact of Easter on disease transmission – especially when looking at SARS-CoV-2.

For the Free State, the Easter weekend runs the risk of being a major catalyst that will lead up to the third wave, says Combrink. “If no interventions are put in place and people do not adhere to non-pharmaceutical interventions to mitigate the spread of the disease, then we will see a steady climb and increase in cases up until that time. This means that the behaviour of people will be the primary driver of transmission for the third wave.”

Reducing the severity of the third wave

According to Combrink, who is involved in risk communication and vaccine analytics with other members of the UFS, we may be able to reduce the severity of the third wave if the variant remains the same and the vaccination roll-out plan is in full effect. It will also help if the correct number of people are vaccinated, the general population adheres to PPE and mitigation strategies, and people practise the appropriate behaviour as indicated in all official COVID-19 communication, including the UFS COVID-19 information page.  

According to Prof Felicity Burt and Dr Sabeehah Vawda, both virology experts in the UFS Division of Virology, the current vaccination programme is aimed at reducing the severity of the disease among health-care workers. Prevention of further waves of infection through vaccination will require sufficient coverage to induce at least 70% herd immunity in the country. Currently, no country has achieved that level of herd immunity through vaccine programmes – this is the long-term goal of vaccination. 

“Irrespective of the government’s vaccination programmes and schedules and a virus that may mutate and perhaps become more virulent, the fundamental ways to protect yourself remain unchanged, namely social distancing, wearing of masks, and regular hand washing. People need to realise that this ‘new normal’ is going to be with us for a while and remains the best defence against all SARS-CoV-2 viruses and even provides protection against other respiratory pathogens.”

Vaccines and mutations

The exact frequency of mutations differs between different types of viruses, but generally, SARS-CoV-2 is known to have a slower ‘mutation rate’ than other RNA viruses because of its built-in ‘proofreading’ enzyme. The true mutation rate of a virus is difficult to measure, as the majority of mutations will be lethal to the virus. Irrespective, very few have actually resulted in clinical impact. 

“This highlights the rather gradual process of mutation, so vaccines should remain effective or at least partially effective in the near future, as they elicit antibodies that target different parts of the virus. Continuous surveillance of SARS-CoV-2 is necessary and ongoing to monitor for changes that may impact vaccines and diagnostic tests,” the experts say.

According to Prof Burt and Dr Vawda, scientists are continuously monitoring the situation to detect if the current vaccines would remain effective and to try to adjust them accordingly. How or when the virus will mutate in a clinically significant way is unknown, so at this point, the current vaccines have been shown to be effective against severe disease and hence have application in reducing significant disease. 

“There remains a lot unknown about the extent of protection and the duration of protection, and it is obviously hoped that the vaccine’s immune response in the human body would be able to provide at least some protection or decrease the possibility of severe disease even against potentially newer variants.”

UFS centre to enhance excellence in agriculture

The national Department of Agriculture (DoA) appointed the Centre for Agricultural Management within the Department of Agricultural Economics at the University of the Free State (UFS) as the centre of excellence to roll out the excellence model for small, medium and micro enterprises (SMME’s) for farmers in the Free State.

The centre was launched this week on the university’s Main Campus in Bloemfontein.

The excellence model, which is used worldwide, was adapted by the Department of Trade and Industry as an SMME Excellence Model. The DoA then adapted it for agricultural purposes.

“The excellence model aims to assist farmers in identifying gaps in business skills. These gaps will be addressed by means of short courses. It will help to close the gap between the 1st and 4th economy,” said Dr Wimpie Nell, Director of the Centre for Agricultural Management at the UFS.

The UFS – as co-ordinator of the SMME Excellence Model – the DoA, the private sector, municipalities, small enterprise development agencies, and non-governmental organisations will be working together to enhance excellence in agricultural businesses in the Free State.

The benefit of the model is that it changes the mindset of emerging farmers to see agriculture as a business and not as a way of living. Dr Nell said: “We also want to create a culture of competitiveness and sustainability amongst emerging farmers.”

“The Free State is the second province where the model has been implemented. Another four provinces will follow later this year. Altogether 23 officers from the DoA, NGO’s and private sector have already been trained as facilitators by the Centre of Excellence at the UFS,” said Dr Nell.

The facilitator training takes place during four contact sessions, which includes farm visits where facilitators get the opportunity to practically apply what they have learnt. On completion of the training facilitators use the excellence model to evaluate farming businesses and identify which skills (such as financial skills, entrepreneurship, etc.) the farmers need.

The co-ordinator from the Centre of Excellence, Mr Petso Mokhatla, will monitor the facilitators by visiting these farmers to establish the effectiveness of the implementation of the model. Facilitators must also report back to the centre on the progress of the farmers. This is an ongoing process where evaluation will be followed up by training and re-evaluation to ensure that successful establishment of emerging farmers has been achieved.

According to Ms Kefuoe Mohapeloa, Deputy Director from the national Department of Agriculture, one of the aims of government is to redistribute five million hectare of land (480 settled people per month) to previously disadvantaged individuals before 2010. The department also wants to increase black entrepreneurship in rural areas by 10% this year, increase food security by utilising scarce resources by 10%, and increase exports by black farmers by 10%.

“To fulfill these objectives it is very important for emerging farmers to get equipped with the necessary business skills. The UFS was a suitable candidate for this partnership because of its presence in the Accelerated and Shared Growth Initiative of South Africa (ASGISA). With the Jobs for Growth programme, ASGISA is an important extension to the Centre of Excellence and plays a major role in the implementation of the model to improve value-chain management,” said Ms Mohapeloa.

Twenty facilitators will receive training in June and another 20 in October this year. “The more facilitators we can train, the more farmers will benefit from the model,” said Dr Nell.
