Wastewater surveillance has proven to be a valuable tool in monitoring community health, especially during the COVID-19 pandemic. A new study conducted by Jay Bullen of Untap Health in London, U.K., Charlotte Hammer of the University of Cambridge, and their colleagues delves into the benefits of wastewater surveillance for multiple pathogens at smaller, site-specific scales.
The research focused on monitoring wastewater concentrations of various viruses at five different sites in the U.K., including an office, a charity center for elderly citizens, a museum, a university co-working space, and a care home. By analyzing daily wastewater levels of viruses such as SARS-CoV-2, influenza A and B, RSV A and B, and norovirus GI and GII, the researchers were able to identify local trends that were not captured in larger surveillance programs.
The study revealed that wastewater surveillance was particularly useful in capturing site-specific events, such as staff illness, cleaning practices, and holidays. For instance, at the care home where the community had less contact with the larger regional community, wastewater data provided insights into local events that were not reflected in public health data. On the other hand, in larger, more open communities like the university space, wastewater data closely aligned with public health data.
Moreover, some sites began using the wastewater data to inform disease prevention efforts, such as implementing enhanced cleaning routines and promoting hand hygiene practices. The researchers suggest that near-source wastewater monitoring could benefit local communities by providing early warnings of disease outbreaks and enabling tailored infection prevention and control measures.
The authors emphasize the importance of further research to refine the understanding of the benefits of near-source wastewater surveillance. They envision a future where wastewater monitoring is scaled across different communities to enhance local infection prevention and control measures, ultimately reducing the impact of outbreaks.
This study, published in the open-access journal PLOS Global Public Health, highlights the potential of wastewater surveillance as a cost-effective and efficient method for monitoring community health. By leveraging wastewater data, local communities can proactively address disease spread and improve public health outcomes.
