A raft of Sydney suburbs have been urged to get tested for coronavirus after traces of the deadly virus were found in sewage.
Fragments of the virus were detected at treatment plants at Liverpool, Warriewood and North Head, the NSW Health Department said on Sunday.
The Liverpool plant includes a catchment of about 180,000 people from suburbs including Bardia, Hinchinbrook, Hoxton Park, Abbotsbury, Ingleburn, Prestons, Holsworthy and Edmondson Park.
“NSW Health urges everyone living or working in these suburbs to monitor for symptoms and get tested and isolate immediately if they appear,” a statement warned.
The Warriewood plant services about 70,000 people from the northern beaches while the North Head facility takes in a catchment of 1.3 million people from Sydney, north of the Parramatta River from western Sydney to Manly.
These detections “likely reflect” known confirmed cases in these areas, the health department said.
But it urged anyone who lives or works in the area to watch for symptoms and get tested as well as isolate if they appear.
The detections come as New South Wales recorded a week without a new, locally acquired infection of the virus.
Three cases were recorded from overseas travellers in hotel quarantine in the 24 hours to 8pm on Saturday, according to the health department.
The results come from 11,344 tests taken in that period with people showing even mild symptoms urged to get a test.
“High testing rates are necessary to give confidence that no cases are going undetected in the community,” NSW Health’s Dr Christine Selvey said.
