Max du Preez, Editor: Vrye Weekblad (top left), was the facilitator was the facilitator for Thursday’s UFS Though-Leader webinar that included Prof Salim Abdool Karim, Director: Centre for the AIDS Programme of Research in South Africa (CAPRISA) and Chair: South African Ministerial Advisory Committee on COVID-19 (top right); Prof Glenda Gray, President and CEO: South African Medical Research Council (SAMRC) (bottom left); and Prof Felicity Burt from the UFS and NRF-DST South African Research Chair in Vector-borne and Zoonotic Pathogens Research (bottom right), participated in Thursday’s Though-Leader webinar.

Although the decline in COVID-19 cases is a promising sign for South Africa, there are concerns about a second surge, and the country should not become complacent.

This was the opinion of the three experts who took part in the first Thought-Leader webinar presented by the University of the Free State (UFS) on Thursday, 13 August. The 2020 UFS Thought-Leader Webinar Series, themed 'Post-COVID-19, Post-Crisis', is taking place in collaboration with Vrye Weekblad as part of the Vrystaat Literature Festival’s online initiative, VrySpraak-digitaal.

The panellists included top experts such as Prof Salim Abdool Karim, Director: Centre for the AIDS Programme of Research in South Africa (CAPRISA) and Chair: South African Ministerial Advisory Committee on COVID-19; Prof Glenda Gray, President and CEO: South African Medical Research Council (SAMRC); and the UFS’ Prof Felicity Burt, NRF-DST South African Research Chair in Vector-borne and Zoonotic Pathogens Research.
Prof Karim said the downward decline is consistent and the number of patients presenting at hospitals is also declining.
 
Promising trend of decline
“What we are seeing is a promising trend, and it looks like we are on the decline. A question that I am often asked is: Is the worst over? The answer is not clear-cut. We are concerned about the risk of a second surge. If anything – what really concerns me at this stage is a second surge, as I think about how the pandemic may play out over the next few weeks,” said Prof Karim. 

He also referred to countries such as the US, Spain, New Zealand, Vietnam, and South Korea, which are now facing a second surge. 

“We need to be very careful; this is not the time for complacency. We need to maintain all our efforts. If we look at one of the key drivers, it is the need for our economy to restart. We need to get people back to work,” said Prof Karim. 
According to him, we have to look at COVID-19 not as a sprint, but as a marathon. “As we learn to co-exist with this virus, aim for containment; we need to plan for the long term. Even if we get a vaccine, it is unlikely that we will be able to vaccinate a substantial part of our population before the end of next year.” 

“We need to transition from being scared to a situation where we can control our risk. When we know that we can control the risk and then influence the risk, we influence the risk of everyone around us. Part of the new normal is the strategy of mitigation with prevention, plus preventing outbreaks.”

Schools and vaccine development
Prof Gray spoke about whether schools should be open and the role that children play in transmission, how to avoid the second wave, how to adjust our testing, and the exciting news around vaccine development. 

As a paediatrician and a parent, Prof Gray said she believes schools should open. “Children have a different immune response to COVID-19. They have different immune responses to Coronavirus and they probably have less viral-load copies which makes them have milder diseases. They are lucky to have been spared from symptomatic or severe disease,” said Prof Gray. 

According to her, schools need to be de-risked as much as possible, with children and teachers wearing masks, washing hands, making sure that there is good ventilation in the school and that windows are wide open. 

“We also need to know about the comorbidity and ages of teachers, so that we can keep the sick and older teachers out of direct contact. The younger teachers with no comorbidities should be teaching. 

“We also know from our experiences with health workers that transmissions happen in the tearoom where teachers take off their masks and talk. We need to minimise the transmissions in tearooms and protect teachers and parents who are older and have comorbidities.”  

Prof Gray said from data she has seen, schools play a very small role in the transmission of COVID-19; a lot more (transmissions) happen in the community, by commuting, and overcrowded taxis.

Prof Gray agreed with Prof Karim that we should be concerned about a second wave, and that we need to make sure community transmissions are minimised. 

Regarding a vaccine, Prof Gray said a global race is on to find a vaccine. “The more vaccines the better, we want more vaccines to work. The more vaccines, the more affordable they are, and the more doses are available.”

One health approach

During her presentation, Prof Burt said the current response to outbreaks is largely reactive rather than proactive, and “if we have more of a one-health approach, with forecasting, early detection, and a more rapid response, we could have an impact on public health in the future”.

UFS to host one of three world summits on crystallography

Prof André Roodt from the Department of Chemistry at the University of the Free State (UFS), co-unveiled a special plaque in Poznan, Poland, as president of the European Crystallographic Association, to commemorate the Nobel prize winner Max von Laue at a special Laue Symposium organised by prof Mariusz Jaskolski from the A. Mickiewicz University in Poznan.

Max von Laue, who spent his early childhood in Poznan, was the first scientist to diffract X-rays with a crystal.

2014 has been declared by the United Nations as the International Year of Crystallography, and it was recently officially opened at the UNESCO headquarters in Paris, France, by the Secretary-General of the UN, Ban Ki-moon. The International Year of Crystallography celebrates the centennial of the work of Max von Laue and the father and son, William Henry and William Laurence Bragg.

As part of the celebrations, Prof Roodt, president of the European Crystallographic Association, one of the three regional affiliates (Americas, Europe and Africa; Asia and Australasia) of the International Union of Crystallography (IUCr), was invited by the president of the IUCr, Prof Gautam Desiraju, to host one of the three world summits, wherein crystallography is to showcase its achievements and strategise for the future.

The summit and conference will take place on the Bloemfontein Campus of the UFS from 12 to 17 October 2014 and is titled: 'Crystallography as vehicle to promote science in Africa and beyond.' It is an ambitious meeting wherein it is anticipated to bring the French-, English- and Arab-speaking nations of Africa together to strategise how science can be expanded, and to offer possibilities for this as nestled in crystallography. Young and established scientists, and politicians associated with science and science management, are the target audience to be brought together in Bloemfontein.

Dr Thomas Auf der Heyde, acting Director General of the South African Department of Science and Technology (DST), has committed some R500 000 for this effort, while the International Union of Crystallography provided R170 000.

“Crystals and crystallography form an integrated part of our daily lives, form bones and teeth, to medicines and viruses, new catalysts, jewellery, colour pigments, chocolates, electronics, batteries, metal blades in airplane turbines, panels for solar energy and many more. In spite of this, unfortunately, not many people know much about X-ray crystallography, although it is probably one of the greatest innovations of the twentieth century. Determining the structure of the DNA was one of the most significant scientific events of the 20th century. It has helped understand how genetic messages are being passed on between cells inside our body – everything from the way instructions are sent to proteins to fight infections, to how life is reproduced.

“At the UFS, crystallography finds application in Chemistry, Physics, Biology, Mathematics, Geology, Engineering and the Medical fields. Crystallography is used by the Curiosity Rover, analysing the substances and minerals on Mars!

“The UFS’s Departments of Chemistry and Physics, in particular, have advanced instruments and important research thrusts wherein X-ray crystallography has formed a central part for more than 40 years.

“Crystallography has produced some 28 Nobel prize winners over the past 100 years and continues to provide the means for fundamental and applied research,” said Prof Roodt.
