All South African citizens are by now aware of the global pandemic caused by the COVID-19 virus. Our president, Cyril Ramaphosa, placed the entire country in a state of lockdown to limit the spread of the virus in South Africa. Schools, tertiary institutions, churches, and numerous businesses (which do not provide essential services) had to close. The lockdown aims to ensure that citizens stay at home, isolate themselves from others, and that those who can work from home should do so. The consequence and reality, however, is physical and social isolation, which of course also means that many people are currently alone and lonely.

Working from home
There are several benefits to working from home; for example, you can manage your own time, work in comfortable clothes, and you can work undisturbed and with less interruptions. Although the lockdown – and thus social isolation – will only last for (maybe) 21 days, there are psychological disadvantages associated with social isolation. Many people could soon become discouraged and demotivated because of the time away from others due to social isolation. Social isolation is the absence of social interaction, contact, and relationships with loved ones, colleagues, strangers, and even society as a whole. Humans, by nature, are social beings who strive towards social interaction with others, and social interaction is essential for people's well-being and survival. Although it is also natural to occasionally seek alone time, the effect of social isolation can have negative consequences for the emotional well-being of individuals.

Consequences of social isolation
Studies have shown that long-term social isolation has dire consequences for people's physical and mental health, such as increased risk of premature death and higher tendencies towards depression. Still, social isolation – even for a few weeks – can also have a negative psychological impact on people's lives. Social isolation can lead to feelings of despair and loneliness, depression, anxiety, substance abuse, and sleep difficulties. Furthermore, in times of social isolation, individuals tend to exhibit more forms of unhealthy behavior than usual, such as smoking and drinking more alcohol. Feelings of loneliness tend to worsen when individuals are isolated with people with whom they do not have a close relationship and, therefore, loneliness becomes a more significant struggle during times of social isolation. This can turn into a vicious cycle, leading to more loneliness and depression if not dealt with. During these isolation periods, individuals may even become complacent, and consequently do not have goals and routines.

Social isolation will, however, affect people differently. More extroverted people will long for social engagement with others and might feel as if they want to climb the walls. They will just want to go shopping and spend time with others. More introverted individuals may enjoy this alone time and spend time taking long baths and reading books. However, everyone will start to experience social isolation negatively at some point. Families will, for example, not be used to these extended periods together, and this may lead to increased conflict between family members. Individuals with big homes can spend time in their gardens and exercise on their lawns, but what about those individuals living in overcrowded flats or informal accommodations. Such individuals may be more inclined to experience depression, anxiety, and loneliness. Individuals with drinking and smoking habits may become more dependent on these substances during the lockdown. Also keep in mind those individuals who have small children who are now home for several weeks and need to be kept busy and entertained by their parents. Parents are not used to being responsible for keeping their children busy productively.

Socializing through social media
People might still be fine and feel good now, but we have not yet reached the halfway point of the lockdown, and how will individuals cope if the lockdown is extended. There is, of course, hope. It is important to remember that although people are currently isolated, they can still attempt to be social by using various forms of social media. Recent studies have shown that individuals may experience less loneliness when interacting with others through various forms of social media. Accordingly, individuals need to make more contact with others and reach out to those that they have not heard from in a while. Social interaction is crucial, as many of us need social interaction to cope with daily challenges. However, also beware of negative content or fake news. Social interaction via the internet might not fulfil everyone’s needs as with interpersonal communication and interaction, but it still allows us to experience a sense of congregation and community.

Stay positive
The reality is, however, that many people also do not have access to the internet and social media, and therefore cannot communicate with others. It then becomes essential that people should continue with certain routines in their lives and to not just sit in front of the television. People still have to set goals (even smaller goals) for themselves and try to achieve them. Everyone should try to change their perspective by trying to stay positive. People need to attempt any form of exercise and keep their minds occupied with books or brain games. Fortunately, when it comes to children, most schools have provided parents with study material to keep their children busy educationally. Alternatively, parents should create some form of structure and routine for their children during the lockdown. Families can play board games and create their own fun activities. Children should also be allowed to engage with their friends via social media if they become lonely. And parents should allow their children to share their worries and concerns openly. Individuals need to be prepared, because when this mandatory period of isolation ends, everyone will have to resume their normal activities.

Get help
If not addressed, these experiences of overwhelming loneliness, sadness or lack of meaning may continue long after the lockdown has ended. Individuals who experience depression and loneliness after the lockdown should reach out to others, try to eat healthy foods, do fun things, and exercise more. Such individuals should also consider contacting mental healthcare professionals for assistance. They can also visit the South African Depression and Anxiety Group's website or Facebook page for help.

Social distancing is vital at this stage, but as South African citizens, we must remember that we are not going through this alone. We are isolated from others, but together we are all fighting the same battle against COVID-19.

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.
