Victoria has reported 1312 COVID-19 infections and a further five deaths, as health authorities await genomic sequencing results from a suspected Omicron variant case.

The health department on Wednesday confirmed the state was managing 11,331 active cases, down from 13,050 on Tuesday.

There are 303 virus patients in the state’s hospitals. They include 97 in intensive care and 27 requiring ventilation.

The seven-day hospitalisation average sits at 297.

Testers processed 79,490 results on Tuesday, while 3858 people were vaccinated in state-run hubs.

More than 91 per cent of Victorians over 12 are fully vaccinated.

The latest figures come after a fully-vaccinated international traveller returned a positive test on Monday without the S gene dropout, a feature of the Omicron variant.

The traveller arrived from the Netherlands via Abu Dhabi on Friday and opted to enter hotel quarantine, meaning they have not been in the community while infectious.

All other passengers on board the international flight are being followed up to ensure they have been tested, in line with current requirements for overseas arrivals.

Victoria is yet to record a case of the fast-spreading variant, with infections found in NSW, the ACT and Northern Territory.

Meanwhile, the Victorian government has announced it will pour $21 million to establish a mRNA research program as part of its push to use the technology to manufacture vaccines on an industrial scale for future pandemics.
