NSW Health last night issued a COVID alert for Bourke after fragments of the virus were found in the sewage plant in the North West town.
In a release last night, NSW Health said: "NSW Health's ongoing sewage surveillance program has detected fragments of the virus that causes COVID-19 at the Bourke sewage treatment plant in western NSW.
"The sample was taken on Tuesday 22 June at a sewage treatment plant which serves an area of about 2,000 people. There have been no prior detections at this site.
"NSW Health is urging everyone in this area to be vigilant for the onset of any cold-like symptoms, and to get tested immediately and isolate if they appear.
"Additional testing capacity is being urgently arranged for the local community, details of which will be released as soon as possible."
Meantime Northern Tablelands MP and Ag Minister Adam Marshall has put out a video after he contracted COVID while eating at a pizza place in Paddington on Monday night and is now in 14 days isolation.
He has promised not to do anything to take the virus back to the Northern Tablelands. His office has been forced to cancel dozens and dozens of ministerial appointments, many of his staff have had to have multiple tests.
