Dr Renée Street pioneers Global Wastewater Surveillance research

Dr Renée Street has been named by the Rockefeller Foundation as one of four women pioneering advancements in global wastewater surveillance.

As climate change alters global disease patterns and triggers cross-species viral transmissions, wastewater epidemiology has emerged as a critical tool in the public health field.

During the COVID-19 pandemic, Dr Street and her team navigated the challenges of sample collection and analysis, so that public health officials could get usable and reliable results on a weekly basis. The SAMRC Wastewater Surveillance and Research Programme is a collaboration between the E&HRU, Biomedical Research Innovation Platform (BRIP) and Genomics Platform. Lab technicians from historically disadvantaged institutions were also trained in sampling and analysis methods.

After a cholera outbreak hit the country in May 2023, the research focus shifted to being able to detect it. This year the team pivoted again, which led to introducing a multi-pathogen panel that looks at 24 different pathogens – worsening due to climate change.

“Tracking pathogens through wastewater surveillance is about staying ahead of outbreaks to protect communities from public health threats.”

One Health: Environmental Exposures Seminar | 26-27 September 2023

Around the world, there is growing concern about our changing environment. For example, climate change and rising temperatures contribute to the movement of zoonotic hosts and vectors to different elevations and latitudes, bringing unfamiliar exposures to vulnerable human and animal populations. At the same time, adverse weather events may compromise the fundamental pillars of public health, such as floods – leading to the overflow of wastewater treatment facilities and consequent waterborne disease outbreaks. There is also growing concern about the accumulation of persistent toxic substances in the environment and in the fatty tissues of animals, that lead to distribution of pollutants to humans through the food pathway, such as metals in fish, for example.

In recent decades, there has been a growing realization that addressing these complex environmental and health challenges requires a systematic approach. The One Health approach encompasses the interconnection of environmental, animal, and human health as key outcomes. It provides a holistic framework to engage with these challenges in an integrated way, ensuring the well-being of all living beings and our shared environment.
