Why now
Genomic sequencing has rapidly matured into a powerful tool for detecting and characterising pathogens - quickly, accurately, and at scale. In parallel, wastewater sampling has gained momentum since the COVID-19 pandemic as a relatively low-cost, unobtrusive approach to community-level disease surveillance.
Combining wastewater surveillance with multi-pathogen genomics can provide a timely snapshot of which infectious disease threats may be circulating in a population. This is especially valuable in lower-resource settings where clinical surveillance can be constrained by limited access, uneven reporting, or delayed diagnosis.
Now is the right time to expand this integrated approach as an early warning system that enables public health officials to detect emerging risks sooner and act faster.
