Victoria has another 1206 COVID-19 cases and a further two deaths, as the state continues to probe four suspected Omicron variant infections.

The health department on Friday confirmed the state was managing 11,145 active cases, slightly down from 11,224.

There are 313 patients in hospital, 104 of whom are in intensive care and 25 needing ventilation.

The seven-day hospitalisation average sits at 306.

Testers processed 66,784 results on Thursday, while 3925 people were vaccinated in state-run hubs.

Victoria’s double-dose vaccination rate for those 12 and over has hit 92 per cent.

The latest figures come after another two suspected community cases of the Omicron variant were discovered in Victoria, on top of two revealed on Wednesday.

Genomic sequencing is underway to confirm if the four infected people – two from the City of Brimbank, one from the City of Casey and one from the City of Wyndham – have the variant.

At least three of the cases are not linked to international travel and their source remains unknown.

Workers and travellers through Melbourne Airport have also been put on notice after two wastewater detections showed traces of the Omicron variant on December 1 and 2.

Premier Daniel Andrews has reiterated the state is not chasing an “Omicron zero strategy”, describing it as unachievable.
