The first 1 000 days of a baby’s life, from conception to the age of two, constitute a critical period during which children’s brains form as many as 1 000 neural connections every second – a pace that will not be repeated in their lifetime.

These connections are the building blocks of every child’s future, which makes the role of a campaign like the First 1 000 Days vitally important. It highlights the importance of stimulation and learning from the earliest possible moments, good nutrition for expectant mothers, prevention of malnutrition of children, and early diagnosis of chronic, life-threatening illnesses and developmental disorders.

This is according to Dr Nomakhuwa Tabane, Head of the Department of Paediatrics and Child Health at the University of the Free State (UFS). The campaign was promoted by Dr Tabane’s department in partnership with the Mother and Child Academic Hospital (MACAH) Foundation.  The annual campaign kicks off on 1 November each year.

“There are certain factors that can interfere with this process and result in irreversible damage to children’s brain development, poor growth, and compromised immunity. Those conditions include prematurity, ischaemic brain damage, and infections. These are also the top contributors to the neonatal mortality.

“In the one-month to 49-month-old period, the causes of mortality and morbidity that affect brain development and growth include respiratory illnesses like pneumonia, diarrhoeal diseases, and malnutrition,” says Dr Tabane. 

Aims of the campaign

The First 1 000 Days initiative promotes excellent mother, infant, and child healthcare by supporting community-based programmes that drive the message of the importance of the first 1 000 days of life to teenagers, young adults, healthcare workers, and the public. This initiative aims to bring about interventions that can address the Under-5 Mortality Rates (U5MR), including Neonatal Mortality Rates (NMR), Infant Mortality Rates (IMR), and Perinatal Mortality Rates (PMR).

“The campaign also aims to improve the growth and development of children in their first 1 000 days of life from conception until they are two years old. It also aims to improve expectant mothers’ health and prevent and decrease maternal mortality in the Free State, as well as to prevent unwanted pregnancies, focusing on decreasing teenage pregnancies.”

According to Dr Tabane, the 2020 South African UN Inter-agency Group for Child Mortality Estimation (UNIGME) estimate for U5MR was 32 deaths per 1 000 live births, NMR of 11 per 1 000 live births, and infant mortality rate (IMR) of 26 per 1 000 live births as compared to the Medical Research Council (MRC) estimate of U5MR of 28 per 1 000 live births, NMR of 12 per 1 000 live births and IMR of 21 per 1 000 live births (15).

South Africa behind other BRICS countries

Based on the 2020 UNIGME report, says Dr Tabane, South Africa has achieved the Sustainable Development Goals (SDG) goals of NMR and the U5MR. South Africa’s indicators were much better than the UNIGME and the MRC 2020 estimates, but it still falls behind other BRICS countries.

“In contrast to other BRICS countries (Brazil, Russia, India, China, and South Africa), UNIGME reports that in the same reporting period of 2020, China’s U5MR was seven per 1 000 live births, Brazil's 15 per 1 000 live births, and Russia's five per 1 000 live births (16). In 2020, the South African national in-hospital neonatal mortality rate (NMR) based on DHIS data was 12,0 per 1 000 live births; the infant mortality rate (IMR) was 15.1 per 1 000 live births, and the under-5 mortality (U5 MR) rate was 16.9 per 1 000 live births, with differences amongst provinces,” says Dr Tabane.

The first 1 000 days campaign’s interventions include education to prevent illnesses and deaths and promote good health, growth, and development. While many training programmes on child survival strategies have been rolled out (e.g., MSSN, HBB, ETAT, AANC, ESMOE, and IMCI), in-service training still has significant gaps.

Other interventions include preventing unwanted and unplanned pregnancies, providing healthcare support for therapeutic and interventional care, strengthening the implementation of the existing strategies developed by the Department of Health to reduce Maternal and Child Mortalities, and monitoring and evaluating the interventions.

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.
