“…The SARS-CoV-2 virus has caused unprecedented damage in recent human history and brought humankind to a complete halt for an entire year 2020 (Zhu et al, 2020). The urgent need of increased diagnostic testing was felt as the COVID-19 epidemic advanced into a pandemic (Sarkar et al, 2020). This was also necessary to distinguish SARS-CoV-2 from closely related other respiratory infections (WHO, 2020).…”

Background: The threat of coronavirus disease 2019 (COVID-19) is still looming large on humankind. Pooled-testing can serve as a method of choice for current and future mass surveillance. The aim is to economically benefit in the face of resource-paucity in overburdened public health systems. Methods: This study assesses the viability of pooled-testing with viral transport media (VTM) for COVID-19 diagnosis. For this, we designed high-dilution pools using samples with wide-ranging viral loads. The testing employs common TaqMan-based RT-PCR assay considering biological as well as technical replicates. Results: We successfully detected a single positive sample in a pool (up to 1/32 dilutions) without loss of sensitivity. The results from biological and technical replicates were found to be satisfactory and reproducible for the objective. We have also discussed multiple variables that can influence the final outcome of pooled testing strategy. Conclusions: We show that pooling approach can be efficiently applied for the detection of SARS-CoV-2. We report improved pooling success compared to published studies, even with very low input volume of media, in very high pool-sizes using low-viral load samples. We consider these features to be unique to this study. The study outcomes are encouraging and can be implemented in public health settings to conserve precious resources.

Background: With the observed cases of the coronavirus disease 2019 (COVID-19) pandemic in South Africa, coupled with varying levels of national lockdowns, food retail supply chains in South Africa were adversely affected. The pandemic affected international travel, global logistics, supplier production and stockpiles at the supply end, which resulted in shortages at retailers and increased prices for basic food items.Objectives: The purpose of this article was to provide insights into and a synthesis of the impact of the COVID-19 pandemic on food retail supply chain models in South Africa.Method: A general review of both academic and grey literature (including commentaries) was studied to draw insights into the issues of food retail supply chain. This was combined with an examination of websites and annual reports of the major food retailers in South Africa to find their responses to the pandemic related to their supply chains.Results: It was found that the investment in supply chains and local supply development and the technology by the large food retailers in the country have paid off in the ways that they have been able to respond to and contain the shocks of the pandemic and point to the local versus the international when thinking about new supply chain models for the post-COVID-19 world.Conclusion: The insights drawn from this article may be useful in building more resilient food retail supply chains in the South African context. This article charts a way for more focused analyses using empirical data to thresh out more nuanced insights that will benefit the food retail supply chain and create a more resilient food system in South Africa.
