Mitigating COVID-19: These Are The Women Who Make Up SA’s COVID-19 Occupational Health Outbreak Response Team

  • 8 min read

Today, we salute South Africa’s extraordinary occupational health experts who are leading the country on national Covid-19 guidelines and procedures, online training and education, as well as surveillance and research. This is with the objective of promoting health and safety in workplaces across the country. Since the outbreak of the pandemic in South Africa, the national Covid-19 Occupational Health Outbreak Response Team (OHORT) was established, bringing together various experts and collectively carrying out rigorous daily online training across many sectors of society to mitigate the burden of the disease.

These experts have trained essential frontline healthcare workers, CEOS, paramedics, government departments, retailers, shop stewards, the food industry, security and cleaning personnel, and many other sectors on how to deal with Covid-19 cases. These detailed training sessions include – but not limited to – what employers should do when a worker tests positive, control measures for workplaces, screening protocol, cleaning and decontamination procedures, compensation matters, the correct methods of donning and doffing of PPE, how to carry out biorisk assessments, and guidelines for all other aspects relating to Covid-19. They have worked tirelessly and continue to train workers from both the formal and informal economy.

They are mothers, daughters and sisters, but they are also exceptional leaders from the National Institute for Occupational Health (NIOH) who are progressing and disrupting the sector like never before. The NIOH – a division of the National Health Laboratory Service (NHLS) – is a World Health Organization (WHO) Collaborating Centre and a Centre of Excellence.
