Melbourne households in the eastern and outer northern suburbs have been urged to monitor for COVID-19 symptoms after traces of the virus were detected in their sewer catchments.

Victoria’s health department warned that a person “most likely” was shedding the virus after an infectious period, however the detection of the virus could also be due to a person living in or travelling through the area in the early active infectious phase.

People who have developed COVID-19 symptoms in the following areas are “strongly encouraged” to get tested:

Eastern suburbs catchment from 20-24 April Balwyn, Balwyn North, Blackburn, Blackburn North, Box Hill, Box Hill North, Bulleen, Doncaster, Doncaster East, Donvale, Mitcham, Mont Albert, Mont Albert North, Nunawading, Templestowe Lower
