Abstract
AbstractRespiratory syncytial virus (RSV) causes severe infections in infants, immunocompromised or elderly individuals resulting in annual epidemics of respiratory disease. Currently, limited clinical RSV surveillance and the lack of predictable RSV seasonal dynamics and limits the public health response. Wastewater-based epidemiology (WBE) has the capacity to determine levels of health-associated biomarkers and has recently been used globally as a key metric in determining prevalence of SARS-CoV-2 in the community. However, the application of genomic WBE for the surveillance of other respiratory viruses is limited.In this study, we present an integrated genomic WBE approach, using RT-qPCR and partial sequencing of the G gene to monitor RSV levels and variants in the community across 2 years encompassing two periods of high RSV clinical positivity in Northern Ireland.We report increasing detection of RSV in wastewater concomitant with increasing numbers of RSV positive clinical cases. Furthermore, analysis of wastewater-derived RSV sequences permitted subtyping, genotyping, and identification of distinct circulating lineages within and between seasons.Altogether, our genomic WBE platform has the potential to complement ongoing global surveillance efforts and aid the management of RSV by informing the timely deployment of pharmaceutical and non-pharmaceutical interventions.
