The Victorian health department says wastewater sampling has detected viral fragments of Covid-19 in Melbourne's eastern and northern suburbs.

It said in a statement:

Given the current prolonged period of no community transmission in Victoria, it is most likely that this is due to a person or persons continuing to shed the virus after the infection period. However, it could also be due to a person living in or travelling through the area in the early active infectious phase.
