Genomic sequencing: what it is and how it’s being used against Covid-19 in Victoria

Authors: Elias Visontay@EliasVisontay

What is genomic sequencing?

Genomic sequencing analyses the virus sample taken from a diagnosed patient and compares it with other cases.

Prior to Covid-19, genomic sequencing has been used in Australia to trace the source of outbreaks of food-borne bacteria and hospital infections.

After a Covid-19 test (which gathers saliva from the back of the throat and nose) returns a positive result, the swab used goes through several steps to separate the RNA molecules from mucus proteins so they can be captured, then converted into DNA that can be read.
