What does this research mean for the field?

Long-term wastewater surveillance effectively tracks the prevalence and seasonal dynamics of respiratory viruses, with SARS-CoV-2 concentrations predicting clinical cases up to seven days in advance. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Assess the multi-year prevalence, seasonal dynamics, and predictive capacity of SARS-CoV-2, influenza A/B, and RSV A/B through urban wastewater surveillance across pandemic and post-pandemic periods.

Overview

Longitudinal surveillance reveals continuous SARS-CoV-2 and seasonal influenza and RSV circulation in urban wastewater, highlighting wastewater monitoring for early respiratory outbreak detection.

Key Points

Assess the multi-year prevalence, seasonal dynamics, and predictive capacity of SARS-CoV-2, influenza A/B, and RSV A/B through urban wastewater surveillance across pandemic and post-pandemic periods.
Monitored 12 urban sewage locations over a three-year period (November 2021–November 2024) in Burgos, Spain (n = 600).
Concentrated viral particles using an aluminum-based adsorption-precipitation method (mean recovery rate: 28.73% ± 1.40%) followed by nucleic acid extraction and RT-qPCR quantification.
Detected SARS-CoV-2 continuously across all sites with an average concentration of 6.07 ± 0.04 log genomic copies per liter per 100,000 inhabitants.
Identified a significant correlation between wastewater SARS-CoV-2 loads and reported clinical cases, with predictive accuracy improving when incorporating a seven-day lead time.
Observed intermittent detection and lower viral loads for influenza and RSV, alongside altered seasonal patterns and unexpected outbreaks across all three viral groups.
