Testing expert explains why the Health Department has raised alert over COVID-19 in wastewater
Dozens of suburbs are on alert after “strong and unexpected” COVID-19 traces were detected in wastewater.
The Department of Health has asked 246 people, including recently returned travellers from red and orange zones and four close-contacts of the man who tested positive after flying into Melbourne from Perth, to get tested for the virus.
Victoria’s COVID-19 testing commander, Jeroen Weimar, said it was no reason to panic.

Microbiologist and project manager of Collaboration of Sewage Surveillance of SARS-COV-2, which works with health departments to monitor the virus in wastewater, Dr Dan Deere, explained what the recent detections mean.
“It just means there’s more chance there’s more of the virus having found its way into the wastewater,” he told Neil Mitchell.
“Either there’s more people that have the virus and are still releasing some of the virus from their system, or it may mean there’s one or two people with a high level of the virus being released into the system.
“Hopefully it’s quite a large number of people shedding a low levels of virus but there’s a theoretical possibility it’s a person early on in the stage of infection shedding a higher level of virus.
“That’s why the Health Department has raised a heightened alert and encouraged people to go and get tested if they’ve got any symptoms or they’ve got any concerns.
“I would call it a case of being alert but not alarmed.”
