Genome surveillance of pathogens 

Whole genome sequencing was crucial in combatting the COVID-19 pandemic—from real-time monitoring of SARS-CoV-2 spread and evolution, to guiding public health responses, treatments, and vaccine development.

Building on this, Struelens et al. advocate for integration of pathogen genomic data and epidemiological data into globally interconnected One Health surveillance systems. Their lead article outlines necessary enablers for deploying real-time genomic surveillance of pathogens and antimicrobial resistance worldwide—including data-sharing platforms, new sequencing technologies, and cross-sector collaborations.
