Victoria confirmed its first Omicron case, with an urgent investigation now underway into further cases that might have been in the community.
The confirmed COVID-19 case with the Omicron variant is in a traveller who arrived in Victoria on December 3 on a flight from the Netherlands via Abu Dhabi.
They were taken directly to hotel quarantine and have not been in the community while infectious.
But on Wednesday, the health department said there were further urgent investigations underway with likely Omicron cases detected in the community.
“Two cases have returned results with S gene dropout – a signature of the Omicron variant,” the department said in a statement.
“Cases have been identified in the cities of Casey and Brimbank. Household contacts of these cases have also tested positive and whole genome sequencing is underway to confirm whether these represent the Omicron variant.
“None of these cases are linked to international travel and their source of acquisition is under investigation.
“The department has interviewed the cases and is taking a conservative approach to the designation of their contacts, including in non-household settings.”
More to come.
