Over 200 Victorians will have to undergo another test for COVID-19 after  unexpected fragments of the virus in Melbourne wastewater were uncovered.

Victorian health authorities issued two separate warnings for residents across dozens of Melbourne suburbs over the past week.

The warnings were issued after wastewater testing revealed strong readings of the virus across the city.

Health authorities are now asking 246 Victorians, including four close contacts of a recent positive case along with 242 people who have recently returned from red or orange travel zones to get re-tested “out of an abundance of caution”.

Every one of the 246 people have already returned a negative test result.
