Australia will force returned travellers infected with a mutant strain of COVID-19 into an extended period of quarantine.

NSW has recorded zero new locally acquired cases of COVID-19 in the 24 hours to 8pm last night.
There was one case recorded in a returned traveller.
Two previous cases have been excluded after further investigations, bringing the total number of COVID-19 cases in NSW since the beginning of the pandemic to 4894.
There were 17,431 tests reported to 8pm last night, compared with the previous days total of 12,213.
Yesterdays testing numbers appeared lower after a minor IT issue delayed the inclusion of about 6000 negative tests, which are included in todays numbers.
There were no delays reporting test results to individuals who had been tested.
NSW Healths sewage surveillance program has recently detected fragments of the virus that causes COVID-19 at sewage treatment plants in Camellia and Auburn, which take in a catchment of almost 180,000 people from Lidcombe, Rookwood, Strathfield, Homebush West, Chullora, Rydalmere, Camellia, Rosehill, Silverwater, Clyde, Newington, Sydney Olympic Park, Bankstown, Yagoona, Bass Hill, Sefton, Birrong, Potts Hill, Condell Park, Chester Hill, Old Guildford, Berala, Guildford, South Granville, Auburn, Regents Park, Merrylands, Parramatta, Holroyd, Granville, Harris Park, Merrylands West, and Guildford West.
While this likely reflects known recent confirmed cases in these areas, NSW Health urges everyone living or working there to monitor for symptoms and get tested and isolate immediately if they appear.
