‘Possible case’ as Vic records 21st zero day
Victoria has recorded its 21st straight day of zero new coronavirus cases and no deaths, but a shadow has been cast over the state's streak.
The Department of Health and Human Services confirmed zero new infections and no deaths on Thursday morning.
The number of active cases fell to two, while there were no infections from an unknown source.
But the health department has warned a "possible case" has been reported that is under investigation.
"The initial test result is a weak positive," the DHHS tweeted.
"Further testing today, including review by an expert panel. The case may be a false positive or historic infection.
"Precautionary public health actions in place as investigations continue."
The last positive cases of coronavirus in Victoria were on October 30 when four infections were recorded.
The last time Victoria recorded 21 consecutive days of zero new COVID-19 cases was between February 1 and 21.
Victoria has recorded 20,345 coronavirus cases and 819 deaths since the start of the pandemic, with 19,523 people having recovered as of Friday.
Two Victorians are in hospital with coronavirus.
It comes as the Victorian border was shut to South Australians overnight to prevent an outbreak in Adelaide's north spreading into the state.
Victorian Premier Daniel Andrews said the hard border closure would be in place for 48 hours until a permit system came into operation at 11.59pm on Saturday.
Mr Andrews said the new measures were taken as an "abundance of caution" and followed public health advice due to ongoing community transmission in South Australia.
"It will be in place no longer than it needs to be, we just all have to be as cautious as possible," Mr Andrews said.
"Victorians have worked too hard and given too much to allow anything to put at risk our goal of reaching COVID Normal by Christmas. We'll do whatever it takes to keep Victorians safe."
A total of 18,474 COVID-19 tests results were received in the past 24 hours, which increased from the 17,161 on Thursday.
