Why have these parts of Melbourne seen so many coronavirus cases?
Premier Daniel Andrews says since April, half of Victoria’s new coronavirus cases have come from family-to-family transmission.
The two biggest family clusters in recent weeks are known as the Keilor Downs family cluster and the Coburg family cluster — both named after the suburbs in Melbourne where they’re believed to have begun.
Together, those two family clusters account for 25 cases and include residents in the Hume, Brimbank, Moreland and Cardinia LGAs.
The other main sources of Victoria’s recent COVID-19 cases include two large clusters among workers at the Stamford Plaza Hotel in Melbourne’s CBD and the Rydges on Swanston hotel in Carlton.
These workers, many of whom would live in Melbourne’s suburbs, account for at least 30 cases.
The state’s coronavirus detectives have not been able to put their finger on exactly how the first transmission occurred, but given the hotels were both being used to quarantine returned international travellers, they believe a contractor picked it up from a traveller and the virus then spread among colleagues through a lack of social distancing.
A cluster originally linked back to a patient at Monash Health accounts for seven recent cases.
The Department of Health and Human Services confirmed it was primarily a family-based outbreak concentrated in Melbourne’s south-eastern suburbs.
There have also been two cases linked to the H&M store at Northland Shopping Centre in the Darebin LGA and a smattering of cases at aged care facilities, schools and early learning centres across Melbourne.
Many other cases are still under investigation.
How is Victoria dealing with its COVID-19 hotspots?
After emergency meetings in recent days, the Premier announced some state-wide changes, restricting the number of visitors in homes to five, and limiting outdoor gatherings to 10, from 11:59pm Sunday.
But he also left the door open to initiating tougher lockdowns in the hardest-hit areas.
“It may be the case in the days ahead … where we have seen the data tells us a very clear story that there are extra cases and the highest number of cases, we may need to, for instance, reinstitute the stay-at-home [rule] except for the four reasons,” he said.
Those “four reasons” are shopping for food and supplies, care and caregiving, exercise, and study or work if it cannot be done from home.
Police Minister Lisa Neville said police would be stepping up their enforcement of coronavirus measures, including issuing more fines and conducting more spot checks on people who had been told to self-isolate.
She said the additional enforcement would happen “particularly in those hotspot areas” as well as campgrounds where groups may congregate on the school holidays.
