Health authorities acknowledged that while recently recovered cases may continue to shed virus fragments for several weeks, there was “still a risk of COVID-19 spreading into the community”.
“While there are a number of recently recovered cases in the Auburn area, NSW Health is urging everyone to be vigilant for symptoms – and to get tested immediately and isolate if they appear,” it said.
The suburbs that contribute to the catchment are Condell Park, Bankstown, Potts Hill, Birrong, Sefton, Bass Hill, Chester Hill, Regents Park, Chullora, Homebush West, Strathfield, Rookwood, Sydney Olympic Park, Newington, Granville, Clyde, Lidcombe, Auburn, South Granville, Guildford, Silverwater, Rosehill, Berala and Yagoona.
Anyone who lives or works in these suburbs is advised to be alert for symptoms.
This is the second recent detection in the area.
It comes as New South Wales records a 37th straight day without a new locally acquired COVID-19 case.
There were 10,177 test results processed in the 24 hours to 8pm on Monday, compared to 12,175 the previous day.
