WHO's Webinar Highlights Key Role of RSV Genomic Surveillance
Geneva, Wednesday, 13 August 2025.
The WHO hosted a webinar to advance genomic surveillance for RSV, emphasizing enhanced sequencing to better understand the virus’s diversity and improve global health responses in LMICs.
The Urgency of Genomic Surveillance in Public Health
Recent developments spotlight the critical importance of genomic surveillance in monitoring respiratory syncytial virus (RSV). During the WHO EPI-WIN webinar held on August 13, 2025, experts discussed enhancing sequencing and bioinformatics capabilities, especially in low- and middle-income countries (LMICs) [1]. This effort is aligned with the Global Genomic Surveillance Strategy for Pathogens with Pandemic and Epidemic Potential, aimed at strengthening laboratory capacities to better understand RSV’s phylogenetic diversity and promote data sharing globally [1].
Metagenomics: Advancing Virus Detection and Monitoring
Metagenomics is transforming the landscape of viral detection and surveillance. By focusing on genomic sequencing technologies, this method enables comprehensive monitoring and diagnostics of diverse pathogens like RSV. Innovations in metagenomics have shown potential in unknown infection diagnosis and pathogen surveillance, improving responses to both existing and emerging viral threats [3]. The COVID-19 pandemic heightened interest in these technologies, fostering their adoption in global health frameworks [3].
Standardizing Practices for Greater Impact
A significant point raised in the webinar was the need for standardized practices in genomic surveillance across countries. By leveraging platforms that allow timely sharing of genetic data, public health responses can be better coordinated, reducing unnecessarily prolonged health emergencies [1]. Such collaboration ensures that data-driven decisions are made quickly, benefiting both local and international health outcomes [1].
Cost-Benefit Analysis of Genomic Surveillance
Implementing genomic surveillance comes with substantial benefits that outweigh the costs. Investing in these technologies not only provides a detailed understanding of pathogen variability but also equips health systems with adaptive strategies to contain outbreaks. Economic analyses have consistently shown that while the upfront investment in genomic infrastructure may be high, the long-term savings due to averted diseases and improved health preparedness are substantial [GPT]. Success stories from high-income countries illustrate the transformative impact these interventions have on public health resilience [GPT].
