“When an outbreak occurs, speed and accuracy can save lives.”
Whole genome sequencing, or WGS, has become a vital tool in modern public health. By reading the complete DNA of a pathogen, WGS allows us to understand not just what is causing disease, but how it is spreading, evolving, and responding to treatment.
In this video, we’ll explore how whole genome sequencing is used to detect and investigate outbreaks, strengthen routine surveillance, and combat antimicrobial resistance. From linking cases across time and location, to identifying transmission pathways and resistance genes, WGS provides the detail needed to support timely, evidence-based public health action.
By the end of this video, you’ll see how whole genome sequencing helps protect populations, inform decision-making, and shape effective responses to infectious threats.
