Dinner at a Black Rock cafe first exposed diners at four tables and staff to coronavirus on December 21 – but has now spread to 14 households across the state.
Fresh details have been released showing the way Victoria’s new COVID-19 threat has spread from person to person, now infecting 27 confirmed cases.
A map of the Black Rock cluster reveals it has now spread in five different chains, and is infecting a third generation of cases.
As a result, 900 primary close contacts of the initial Smile Buffalo Thai restaurant diners are now placed in isolation to prevent the outbreak spreading further.
In one instance, five people from three different households who shared a table all became infected, with one transmitting the coronavirus to another person as they returned to homes in Bayside, Glen Eira and Kingston.
Three members of the same Bayside household who dined on another table at the Black Rock restaurant unknowingly passed the virus onto a second generation of cases among friends and family in another three homes, spreading coronavirus to Maroondah, Kingston and Boroondara.
Detailed information released by the Department of Health on Tuesday reveals two Bayside residents who ate together on December 21 subsequently infected three households at Whitehorse, Leongatha, and Monash.
A single diner from Kingston passed on COVID-19 to another member of their own household, before transmission spread to two close contacts in Casey.
A staff member working at the smile buffalo restaurant passed on the virus to another member of their bayside household, however their infection has so far not been linked to any other home.
