A HOTEL quarantine worker has tested positive to COVID-19 in Melbourne just days after another quarantine worker  inside the Grand Hyatt Hotel contracted the UK strain of the virus.

Police and emergency services minister, Lisa Neville said there would be investigation into the latest case.

“At this stage, when we had a look through just this person’s engagement with people as they enter the hotel, as they exit the hotel, as they get moved to health hotels, it appears that there's no breach in that engagement in terms of how close they were, in terms of touching things, in terms of not using infection prevention and control,” she said.

The woman in her early 50s worked as an authorised officer at the Holiday Inn hotel at Melbourne Airport.

She returned a negative test result after a nasal swab on February 4 and returned to work on February 7, where she developed symptoms and later tested positive. More than 11,000 tests were conducted on Monday and there were 20 active cases in the state.
