The World Federation of the Deaf declared September to be Deaf Awareness Month in the 1950s. The Deaf Federation of South Africa (DeafSA) and the South African National Deaf Association (SANDA) both promote awareness of the rights of Deaf persons in South Africa. During Deaf Awareness Week, deaf people are highlighted for their accomplishments and challenges (Deaf Awareness 2022) There growing is awareness about hearing loss, deafness, Deaf culture, and sign language. By understanding deafness and the culture of the deaf community, hearing people can better understand deafness. This year's theme is Building Inclusive Communities for all through the promotion of deafness, Sign Language, and Deaf culture. This piece is a personal reflection of my experiences as a parent of a child who has hearing loss.

Access South African Sign Language as a medium of education 

The education of deaf and hard-of-hearing learners is influenced by several factors both negatively and positively. The lack of Deaf role models for deaf learners, the lack of recognition of South African Sign Language (SASL) as a Language of Learning and Teaching (LOLT), and the lack of fluency in SASL among teachers are some of these factors (Magongwa, 2010). 

The education system is considering bi-modal communication. However, the challenge is finding schools where sign language is taught. A school such as Carel du Toit special school in Bloemfontein has a vision to teach spoken language and support children with hearing impairments. Therefore, it does not offer sign language as a language of education.

Baritimea School for blind and hearing-loss children is an alternative school situated outside Bloemfontein which teaches sign language. One thing about this school is that the kids learn sign language and are confident in their communication. It has an excellent teaching and learning vision which it has managed to actively reach. 

The use of sign language in South Africa has advanced greatly. South African Sign Language (SASL) is set to become the 12th official language of the country after government regulations were passed recently. SASL will now be recognised by the Department of Basic Education as a home language and part of the national school curriculum in grades R-12 under the gazetted amendment. This means that deaf learners will now be able to select SASL as a home language in schools. The department has also made amendments on the passing criteria for learners who select SASL as a home language in schools.

As SASL is the first language for most members of the deaf community, these positive changes will significantly impact learners’ ability to excel in school. “This Regulation is called the Amendment Regulations pertaining to the National Curriculum Statement Grades R-12, 2022 and will come into effect on the date of publication in the Government Gazette.” A growing number of South Africans are fluent in the language, and this will ultimately lead to a more inclusive language and a greater appreciation of deaf culture.

Firsthand experience and the rollercoaster of parenting a child with hearing impairment

I found out about my son’s hearing impairment in the middle of 2018, based on pure maternal instinct. I took the decision to have him assessed by a speech therapist believing he had a simple speech problem. In that initial assessment, it was confirmed that the problem was not speech but that he has severe hearing loss. So began the journey to what felt like a million tests and hospital visits. That year alone my son was under anesthesia more than four times.

Initially, he was fitted with hearing aids, which medical aid did not cover. Other costs included an unbudgeted R30 000 the audiologist charged for the devices. He had grommets fitted by an ENT, his hearing was tested while under anesthesia, and his hearing was tested various times until hearing aids were confirmed not to be the best option for him. 

Due to the severity of his hearing loss, towards the end of 2018, a decision was made to fit him with cochlear implants. With all this technology, a weekly speech therapy appointment, constant mapping, and regular audiograms, we were well on the way to a speaking child. Unfortunately, despite implants, the speech progress was delayed.

Personal interaction with the deaf community 

My first experience of deaf communities and the challenges they face daily in simply trying to communicate and navigate a world that is designed not for them began in my undergraduate year module, introduction to sign language. Although some communities, organisations, and institutions of higher education have tried to move toward inclusivity, one does not need to look too deep to notice that the world is not designed for people with any type of impairment, especially in developing nations.

My experience of the deaf community felt like a mere drop in the ocean when 10 years post my undergraduate learning, I could not engage in a conversation with a deaf person. My limited experience and knowledge of deafness and the community were emphasised when my son was diagnosed with severe hearing loss. I realised there is so much to learn and navigating deafness is sometimes a lonely space, until you find even just one person to help you into the deaf society.

We are now considering bi-modal communication. In addition to working on his speech and hearing, we plan to use sign language to support it, especially for educational purposes. Although progress has been made towards inclusivity, we still have a long way to go.

Positive school experiences for deaf or hearing-impaired children

Deaf children should have the same experiences of schooling as every other child in the country. A clean school, a bright and safe playground, and access to sports facilities at the school. This alone would make a difference in how they experience the world as deaf and hearing-impaired children. Rather than the frustration they face daily, they need to have hope that this world will improve. Their safe spaces should at least be exactly that, safe!

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.
