Victoria has reported nine new local cases of COVID-19 because the authorities are confident that there is no major unknown outbreak of the Delta variant.
Eleven infections were detected within 24 hours to midnight on June 6, although two have already been reported by elderly care operator Arcare.
The outbreak of Arcare Maidstone has grown to six cases after another resident and a registered nurse tested positive.
The 79-year-old resident, who had both doses of Pfizer vaccine, was taken to hospital as a precaution.
A first dose was given to the registered nurse, who last worked at the nursing home on 5 June.
“The staff member did not work at other facilities,” the health department said.
24,265 test results were received and 17,619 vaccine doses were administered on 6 June, while Melbourne put its second weekend in the lock.
It is unclear whether the latest plethora of cases will ward off the city’s hopes of moving to relaxed restrictions from June 4.
Victoria’s Chinese Deputy Chief Health Officer Allen Cheng said officials’ biggest concern was to detect ‘upstream’ transmission.
“Since five per cent of Victorian people have been tested in the last seven days, I would have expected to pick it up if there had been a major outbreak,” he told reporters on June 6.
“The risk does decrease over time, but we are still concerned about it and this is where all our efforts go.”
Professor Cheng said there are no “magical number” of people who have a chance to avoid future blockades, with only two to three percent of Victorians fully vaccinated.
“Once you get much higher coverage rates, it makes a whole lot of things easier,” he said.
‘We may not need the intensity of restrictions. Maybe we can just do contact detection without doing other things on the same level, and that’s the benefit of vaccination. ”
Federal Health Minister Greg Hunt announced on June 6 that an additional 100,000 vaccines will be made available to Victoria.
The federal government has also extended its suspension of JobSeeker’s mutual obligations until June 15.
Ten people are now infected with the Delta variant as part of the outbreak in West Melbourne, with investigators still not sure how it spread in the community.
Authorities continue to search for answers through genomic sequences from across the country.
“We have theories. We are working on it, ”said Cheng.
More than 1,900 primary close contacts of the original Kappa variant-related Whittlesea outbreak were released on 6 June.
Six train services from Merlynston Station to Flinders Street Station were added to the list of more than 350 exposure sites late on June 6 evening.
