Prospective metagenomic sequencing of wastewater across the United States yields robust viral enrichment and concordance with digital PCR measurements.

Hybrid capture metagenomic sequencing achieves over 19% viral read fraction in nearly 450 wastewater samples across the US, enabling effective pathogen detection.

• Why it matters: Current wastewater testing methods are limited to targeted PCR, which restricts detection to specific viruses, leaving gaps in understanding community-wide pathogen diversity and outbreaks.
• What they did: The study applied hybrid capture sequencing to 15 wastewater treatment plants, enriching viral nucleic acids and comparing relative abundance estimates with digital droplet PCR measurements.
• The result: Findings show the approach reliably detects both common and rare viruses, correlates well with PCR data, and offers a scalable method for public health surveillance across diverse geographic regions.
