Fragments of the virus that causes COVID-19 have been found in the sewage system at Burwood Beach Treatment Plant from a sample taken on Wednesday.
The plant has a catchment of around 225,000 people and takes in Newcastle and the surrounding suburbs of Dudley, Charlestown, Jesmond, Lambton, New Lambton, Mayfield, Elermore Vale, Wallsend, Kotara, Garden Suburb, Adamstown Heights, Kahibah, Highfields, Merewether, Waratah West, Georgetown and Carrington.
These plants take in 83,400 people in the Northern Head catchment and 15,000 people on the South Coast.
Those samples were taken on April 22 and April 21 respectively.
NSW Health noted that the positive results could be from recently recovered cases of COVID-19, who can continue to shed fragments of the virus for several weeks after recovering.
“However, NSW Health is concerned that they could signal undetected cases in the community, and asks people in these areas to be alert for any symptoms that could signal COVID‑19,” they wrote in a statement.
There are no new locally-acquired COVID-19 cases detected in NSW today and only one in hotel quarantine, with 7,706 tests conducted yesterday.
One person remains critically ill in ICU and is on a ventilator.
In the state there are 87 people with the virus. Most are not in hospital.
More than half a million doses of coronavirus vaccines have now been administered in the state, with 192,336 jabs given by NSW Health and 361,530 administered by the Commonwealth government.
