Dr Martin Nyaga, Senior Lecturer and Researcher: NGS, will be heading the World Health Organisation Collaborating Centre (WHO CC).

The University of the Free State (UFS) has been designated a World Health Organisation Collaborating Centre (WHO CC), and the university’s Next Generation Sequencing (NGS) Unit, in partnership with the World Health Organisation (WHO), will for the next four years be conducting genome sequencing of pathogenic organisms, including rotavirus strains from the African continent. 

This centre will be part of the Vaccine Preventable Diseases (VPD) Pathogens Genomics Cluster and will run from September 2020 to September 2024. 

Dr Martin Nyaga, Senior Lecturer and Researcher: NGS/Virology, who will be heading the WHO CC, says an institution is designated as a WHO CC by the WHO Director-General and endorsed by the host country’s minister of health to form part of an international collaborative network, carrying out activities in support of the WHO programmess at all levels. A designation as a WHO CC is a time-limited agreement of collaboration between WHO and the designated institution, through which the latter agrees to implement a series of concrete activities, specifically designed for WHO.

A supreme achievement

Says Dr Nyaga: “In my opinion, a WHO CC designation is one of the supreme achievements an institution can be conferred as a recognition for foregoing exceptional collaborative venture with the WHO and showing future potential to assist the WHO with its global programmes and in our case, the WHO Regional Office for Africa region to offer solutions to the WHO VPD Surveillance and pathogens genomics cluster.”

According to Dr Nyaga this designation was awarded to the UFS after the WHO was content with the outcome of a service contract whereby the UFS-NGS unit undertook a pilot rotavirus surveillance project at whole genome level, using two African countries for the pilot, Rwanda and Zambia.

“From the outcomes of the pilot surveillance project between 2017 and 2019, the WHO/AFRO was satisfied with the genomic data that was generated and partially disseminated in scientific databases and journals as a collaborative venture. 

“It was thus proposed to strengthen its existing collaboration with the UFS-NGS Unit, which initiated the application process to designate the UFS-NGS unit as a WHO CC, an initiative that has taken approximately 20 months to finalise through the different phases of the application and approvals for the designation,” explains Dr Nyaga.

The purpose of the WHO CC

The new WHO CC will upon request by the WHO, implement agreed work plans in a timely manner and to the highest possible standards of quality and must comply with the referred terms of reference and conditions. These include: 
• Conducting genome sequencing of pathogenic organisms causing VPD, including rotavirus strains collected as part of the routine VPD surveillance using NGS technology and analysis of the generated datasets using bioinformatics tools.

• Conducting molecular characterisation of specimens collected during outbreaks and public health emergencies as part of the support for monitoring, preparedness and response to VPD disease outbreaks in Africa.

• Provide technical guidance to WHO on strategies to improve laboratory molecular diagnostics, molecular typing and NGS of rotavirus diarrheal strains and other enteropathogens to detect novel and re-emerging strains. 

• Conduct validation of tools and new molecular diagnostics for detection and characterisation of unusual or rare VPD strains to guide studies and development of new vaccines for VPD.

• Organise capacity-building and training workshops on whole genome sequencing of priority VPD pathogenic organisms.

The impact of the WHO CC on the work of the UFS-NGS 

According to Dr Nyaga, the designation brings extra responsibilities to his work and to the activities of the UFS-NGS unit. “Such initiatives are very welcome to enhance the business aspects, research and academic activities of the UFS-NGS unit, as the benefits are quite holistic since the collaboration enhances co-ownership of data and offers opportunities to train postgraduate students and other scientists.

“It also expands the research infrastructure and most importantly contributes to policy for numerous African governments in important decisions such as vaccine implementation activities, from an informed point of view and managing public health needs that require rapid response like outbreaks that may lead to pandemics.”

Emotional health of vulnerable children needs urgent intervention
2014-02-04



In South Africa, thousands of children under the age of 18 are orphaned as a result of HIV/Aids. Experts are worried that these orphans and vulnerable children will experience serious socio-emotional problems and behaviour disorders, should urgent intervention programmes not be implemented urgently.

A study was undertaken by the Centre for Development Support at the UFS, in conjunction with Stellenbosch University and the Houston University in America. The research found that in the Free State province alone, about 15% of orphans and vulnerable children showed signs of psychiatric disorders. Almost half of the children in the study showed signs of abnormal or maladjusted behavioural functioning.

The research team believes that the South African government and the numerous non-governmental organisations put too much emphasis on the physical needs of orphaned and vulnerable children and that their socio-emotional or mental wellbeing receives very little attention.

The nominal financial grant is a welcome relief for some of the needs of this risk group. Researchers are worried, though, that the lack of reliable and culturally-sensitive diagnostic methods for the early detection of psychiatric disorders may pose a challenge when the children reach puberty.

The current study is focusing on the detection of emotional behavioural problems even before adolescence. Questionnaires were distributed across the Free State at clinics, schools and non-governmental organisations dealing with these children. The questionnaires enabled researchers to establish the children's socio-emotional needs.

"Overcrowding in houses where orphans and vulnerable children often live is directly linked to poor socio-emotional health in children," says Prof Lochner Marais from the Centre for Development Support. "The state institutions offering programmes for orphans and vulnerable children overemphasise the physical and/or financial needs of these children. The programme provides, for example, food for the children, grants for the [foster] parents, assistance with school clothes and ensures clinic visits for the children. Of these, only the supply of food has a direct impact on the improved mental health of children."

The study provides, for the first time, a profile of the state of mind of this group, as well as the emotional impact of HIV/Aids – an "urgent matter" according to Dr Carla Sharp from the University of Houston's Department of Psychology. According to Dr Sharp, much more could be done to assist foster parents in addressing the emotional needs of these children. The early detection of behavioural disorders should be the key in intervention programmes.
