"Disability describes the social exclusion and barriers imposed on people with disabilities and impairments evoke an unpleasant feeling in us, and it is the feeling which motivates how we react when we face disability and people with disabilities." – Brian Watermeyer 

South Africa commemorates National Disability Rights Month, known as DRAM, annually between 3 November and 3 December. International Day of Persons with Disabilities, also known as National Disability Rights Awareness Day, is celebrated on 3 December. The theme for 2021 is ‘The Year of Charlotte Manye Maxeke – Create and Realise an Inclusive Society Upholding Rights of Persons with Disabilities’. 

Disability is a quintessential post-modern concept, because it is complex, variable, contingent, and situated. One is always disabled concerning the context in which you are put, subject to many definitions from different perspectives, and is used for various disciplines ranging from medicine, sociology, and political science. To fully comprehend disability, one needs to consider multiple perception models in the quest for a better understanding of disability; so-called ‘models of disability’ emerge in disability research. In line with most notions of disability, it could be associated with the medical model, social model, human rights model, and biopsychosocial model. Disability models aim to demonstrate how society perceives, understands, and addresses the needs of people with disabilities. 

The Disability Models 

Medical model: views disability as a personal tragedy in need of cure and rehabilitation.  

Social model: views disability as predominantly a socially driven issue; allows us to reconstruct social inequality for people with disabilities as a collective experience of discrimination and injustice, rather than a personal tragedy affecting only individuals. However, the model does not address the emotional aspects of disability and the realities of impairment.

Biopsychosocial model: views disability as a combination of an individual's state of health and their surrounding environment, that is, society. By recognising disability as a social construct of intricate variables and interaction of biological factors (genetic, biochemical, etc.) and psychological factors (mood, personality, behaviour, etc.), the social aspects (cultural, familial, socio-economic, and medical, etc.) is to recognise the complexity; specifically, the intersectionality that informs disability is recognised.

The human rights model: assumes that societal barriers can only be removed by guaranteeing rights to people with disabilities. Human rights principles recognise that fundamental rights are inherent in all human beings, regardless of race, gender, ability, and nationality. Therefore, disability rights are viewed as a human right under this paradigm, advocating for equal participation and opportunities for individuals with impairments. 

Promoting the human rights of people with disabilities, the White Paper on the Rights of Persons with Disabilities in South Africa mandates a universal design approach, which is defined as "the design of products, environments, programs, and services to be usable by all persons to the greatest extent possible without the need for adaptation or specialized design."

As per the Global Education Monitoring report on inclusion and education, the Universal Design for Learning (UDL) framework is particularly relevant for a comprehensive understanding of inclusive education as tackling barriers to learning, noting that "the Universal Design for Learning concept encompasses approaches to enhance accessibility and eliminate barriers to learning." Such an approach can help to integrate UDL into the educational system by addressing the various social, emotional, and learning requirements of different groups while working for the universal system-related goal.

South Africa is among the few countries in the world to have signed and ratified the most acclaimed global convention on disability in 2007. The international trend endorsed by the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) seeks to promote, protect, and ensure the full and equal enjoyment of all human rights by persons with disabilities. Although disability is varyingly defined, and definitions change across time and space, the UNCRPD defines persons with disabilities to include long-term physical, mental, intellectual, or sensory impairments, which in interaction with various barriers may hinder their full and effective participation in society on an equal basis. For this reason, creating and realising an inclusive upholding of the rights of persons with disabilities is critical in building an enabling environment for all. However, despite progressive legislative structures in South Africa, persons with disabilities continue to face barriers that prevent equal access to opportunities and participating fully in all aspects of life. It is primarily due to inaccessible infrastructure, prejudice, stigmatisation, discrimination, and attitudinal behaviour towards persons with disabilities, which often result from a lack of understanding.  

According to Stats SA, 80% of persons with disabilities aged 20-24 are not attending tertiary education, yet the population of students with disabilities at tertiary institutions is just 1%. It is also revealed that there is a strong demographic gap between races. Access to education is necessary for advancing sustainable development, but it is evident that inclusivity within tertiary education remains out of reach for many.  The University of the Free State aims to foster disability inclusion within the Integrated Transformation Plan, which is in line with the universal access approach guided by the Centre for Universal Access and Disability Support (CUADS). 

CUADS, a well-known disability unit, was established in line with non-discrimination legislative changes and inclusive policy frameworks for access and equal participation for students with disabilities. It serves as a bridge between students with disabilities and the institution, ensuring mutual understanding. The majority of such departments are led and managed by women, as women have a dynamic role in enhancing and nurturing the aspirations of children and youth with disabilities to get access to education. Despite the positive role of these departments in the full inclusion of students with disabilities, attitudinal barriers remain a challenge to their non-disabled counterparts. 

Furthermore, female students with disabilities face particularly higher levels of marginalisation and disadvantage because of the double discrimination based on their disability and gender. Their status as women renders them vulnerable to gender-based violence (GBV), including sexual abuse, maltreatment, exploitation, and intimate partner violence (IPV) compared to men with disabilities. 

South Africa has a high prevalence of GBV, especially IPV. Women with disabilities are more at risk and experience an additional layer of violence compared to women without disabilities and men with and without disabilities. It is also revealed that blind women and women with severe intellectual and mental disabilities are equally perceived as highly exposed to GBV compared to women with other disabilities (e.g., if an intellectually challenged individual could not give informed consent and/or when they report it, it will be difficult for them to identify the perpetrator). 

Furthermore, men with disabilities are at greater risk of GBV, but not comparable to women and girls with disabilities. The gap perpetuates unequal gender relations in all contexts of South Africans’ lives. While various organisations seek to promote women's rights in GBV advocacy, there is relatively little emphasis on GBV against persons with disabilities, including violence against women and children. 

To build an inclusive society, one needs to understand intersectionality concepts that provide a prism to comprehend marginalisation and exclusion better. Understanding intersectionality is related to how various identities such as race, gender, class, disability, sexuality, and others intersect – how lived identities are seen as entwined with oppressive systems that are mutually constitutive and reinforcing. Intersectionality as an approach recognises how complex reality is and how this complexity informs social conditions and behaviour; it acknowledges that people's lives are defined by multiple layered identities that derive from social relations, histories, cultures, and other operations of power structures. 
It is an analytical tool for exploring, comprehending, and responding to how gender intersects with different identities and how these intersections lead to distinctive oppression and privilege experiences. Also, intersectionality addresses how social structural norms such as racism, patriarchy, classism, and other social systems of discrimination function and interact to create social inequalities that shape attitudes and behaviour towards those who are different, such as those with disabilities. The approach invites us to shift away from binary thinking and towards a more global human rights stance.

Therefore, higher education institutions have a critical role in shaping the future of society as places where students are educated and prepared for their future vocations. In line with inclusive curricula, the university should introduce disability discourse into models such as UFSS, which is mandatory for all first-years. Also, the institution should increase awareness and visibility by incorporating critical disability messages into all discussions, addressing all aspects; utilising disability posters on campus, and departments such as Residence Life, KovsieSport, UFS Centre for Teaching and Learning (CTL), and CUADS should collaborate to host disability events and heighten communication around it; leveraging other mega events such as national days, themed days, conferences, etc., to spread messages on disability and to build an inclusive society; hosting lectures, debates, and discussions on disability topics and promoting rights of persons with disabilities; and hosting student competitions on equality, justice, and human dignity. Through such interventions, the university will have a community that can facilitate the creation of inclusive spaces in their homes, communities, work, and social areas. Disability should be a collective responsibility to achieve an inclusive society that upholds the rights of persons with disabilities. 

Inclusive legislative policies (i.e., the White Paper on the Rights of Persons with Disabilities, 2018 and the Strategic Policy Framework on Disability for the Post-School Education and Training sector) should guide institutions to ensure that students with disabilities are protected. These documents further promote the right to (inclusive) education, as a universal access approach in education does not benefit only students with disabilities, but everyone.

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.
