More than 22,000 Sydneysiders are on high alert after traces of Covid-19 were found in sewage treatment plants.
Residents living in 15 suburbs have been told to watch out for symptoms and get tested if they develop after the fragments of the virus were found on Sunday at the Brooklyn and Lough Park catchments, NSW Health announced on Tuesday evening.
The Brooklyn treatment plant serves 1000 people living in Dangar Island, Cowan, Brooklyn, Mooney Mooney and Cheerio Point.
The Lough Park catchment serves 21,500 people from Clovelly, Waverley, Randwick, Centennial Park, Queens Park, Bondi, Bondi Junction, Bellevue Hill, Double Bay and Woollahra.
“NSW Health is asking everyone in these areas to be especially vigilant in monitoring for symptoms, and if they appear get tested and isolate immediately until a negative result is received,” the press release reads.
“Anyone with even the mildest of cold-like symptoms is urged to immediately come forward for testing and isolate until a negative result is received.”
NSW recorded 10 new locally acquired cases of Covid-19 on Tuesday - including an eastern suburbs child - bringing the number of cases linked to the Bondi cluster to 21.
The jump in infections prompted state premier Gladys Berejiklian to make masks compulsory until midnight on June 30 on public transport and in most indoor settings for people in Greater Sydney, the Blue Mountains, the Illawarra and Shellharbour.
All of the new cases except for two were already in isolation when tested and all of the cases but one, a student at St Charles Catholic Primary School in Waverley, were linked to existing cases.
Sydney Catholic Schools confirmed the Year 3 student had tested positive for the virus and the school had closed for the final three days of term two while it's cleaned.
Chief Health Officer Kerry Chant said it wasn't yet known how the child contracted the virus and health officials were working to develop a plan for the 365 children to be tested.
