But the positive result could be from a recovered case living or visiting the area still “shedding” the virus weeks after recovering from the infection.
“We have had few of these positive wastewater results recently and, while we haven’t discovered any undiagnosed case of coronavirus, it is possible that there may be an infectious person in this catchment,” Professor Cheng said.
“We encourage people in this area who are symptomatic to be tested and will update the community once more testing results become available. It is also a timely reminder for local businesses to re-check their COVID Safe plans to keep themselves, their colleagues and customers safe.”
Last week, viral fragments were found in wastewater samples from Altona, Benalla and Portland. No cases have been detected in those areas following the findings.
