Our Changing World: What genome sequencing revealed about Covid-19

From Afternoons, 3:35 pm on 23 November 2022

It wasn’t that long ago that genome sequencing was a time-consuming and costly task.

But during the Covid-19 pandemic, it’s become a feature of everyday Kiwis’ vocabulary and a routine part of our response – proving especially useful for contact tracing when unexpected cases popped up out of nowhere. 

New Zealand’s early approach to sequencing the genome of every positive case also revealed important information about the nature of the SARS-CoV-2 virus, such as its ability to spread through the air. 

In this episode of Our Changing World, we talk to two scientists from ESR on the frontline of New Zealand’s Covid-19 genome sequencing efforts: Dr Jemma Geoghegan and Dr Joep de Ligt.
